Как проверить, есть ли имя версии String (found) & gt; Строка, указанная для имени версии в Android [duplicate]

Удивительно, почему все предполагают, что версии состоят только из целых чисел - в моем случае это не так.

Зачем изобретать колесо (если версия соответствует стандарту Semver)

Сначала установите https://github.com/vdurmont/semver4j через Maven

Затем используйте эту библиотеку

Semver sem = new Semver("1.2.3");
sem.isGreaterThan("1.2.2"); // true

Написал небольшую функцию самостоятельно. Симулятор с использованием списков

 public static boolean checkVersionUpdate(String olderVerison, String newVersion) {
        if (olderVerison.length() == 0 || newVersion.length() == 0) {
            return false;
        }
        List<String> newVerList = Arrays.asList(newVersion.split("\\."));
        List<String> oldVerList = Arrays.asList(olderVerison.split("\\."));

        int diff = newVerList.size() - oldVerList.size();
        List<String> newList = new ArrayList<>();
        if (diff > 0) {
            newList.addAll(oldVerList);
            for (int i = 0; i < diff; i++) {
                newList.add("0");
            }
            return examineArray(newList, newVerList, diff);
        } else if (diff < 0) {
            newList.addAll(newVerList);
            for (int i = 0; i < -diff; i++) {
                newList.add("0");
            }
            return examineArray(oldVerList, newList, diff);
        } else {
            return examineArray(oldVerList, newVerList, diff);
        }

    }

    public static boolean examineArray(List<String> oldList, List<String> newList, int diff) {
        boolean newVersionGreater = false;
        for (int i = 0; i < oldList.size(); i++) {
            if (Integer.parseInt(newList.get(i)) > Integer.parseInt(oldList.get(i))) {
                newVersionGreater = true;
                break;
            } else if (Integer.parseInt(newList.get(i)) < Integer.parseInt(oldList.get(i))) {
                newVersionGreater = false;
                break;
            } else {
                newVersionGreater = diff > 0;
            }
        }

        return newVersionGreater;
    }

Если честно, лексикографическое сравнение String будет очень хорошо работать в большинстве случаев.

"1.0.0".compareTo("1.0.1") // -1

Возможен некоторая ошибка, если, например, у нас есть некоторое форматирование в некоторой версии

"1.01.1".compareTo("1.1.0") // -1 should be 1

Это можно легко скорректировать, очистив эти значения и, конечно, предоставив некоторые простые методы.

public class Version implements Comparable<Version>{

    private static final String sanitizeRegex = ".0([1-9]+)";

    private String value;

    public Version(String value){
        if(value == null) throw new IllegalArgumentException("A version need a valid value");
        this.value = value.replaceAll(sanitizeRegex, ".$1");
    }

    public boolean isLessThan(Version o){
        return this.compareTo(o) < 0;
    }

    public boolean isGreaterThan(Version o){
        return this.compareTo(o) > 0;
    }

    public boolean isEquals(Version o) {
        return this.compareTo(o) == 0;
    }

    @Override
    public int compareTo(Version o) {
        return this.value.compareTo(o.value);
    }

    @Override
    public String toString() {
        return value;
    }
}

Если это необходимо, regex удалит удаление 0.

01 -> 1
0 -> 0
00 -> 0
10 -> 10

Это позволяет нам иметь довольно простое сравнение, используя то, что уже существует.

Быстрый тестовый пример, взятый из Ответ Йохана Пола

    System.out.println(new Version("1.2").isGreaterThan(new Version("1.1")    )); // true
    System.out.println(new Version("1.2.1").isGreaterThan(new Version("1.1.2")  )); // true
    System.out.println(new Version("1.1.1").isGreaterThan(new Version("1.1.1")  )); // false
    System.out.println(new Version("1.1.1").isGreaterThan(new Version("1.1")    )); // true
    System.out.println(new Version("1.1.0").isGreaterThan(new Version("1.1")    )); // true
    System.out.println(new Version("1.1-RC2").isGreaterThan(new Version("1.1-RC1"))); // true
    System.out.println(new Version("1.1-RC1").isGreaterThan(new Version("1.1")    )); // true
    System.out.println(new Version("1.0.1").isGreaterThan(new Version("1.1")    )); // false

Вот оптимизированная реализация:

public static final Comparator<CharSequence> VERSION_ORDER = new Comparator<CharSequence>() {

  @Override
  public int compare (CharSequence lhs, CharSequence rhs) {
    int ll = lhs.length(), rl = rhs.length(), lv = 0, rv = 0, li = 0, ri = 0;
    char c;
    do {
      lv = rv = 0;
      while (--ll >= 0) {
        c = lhs.charAt(li++);
        if (c < '0' || c > '9')
          break;
        lv = lv*10 + c - '0';
      }
      while (--rl >= 0) {
        c = rhs.charAt(ri++);
        if (c < '0' || c > '9')
          break;
        rv = rv*10 + c - '0';
      }
    } while (lv == rv && (ll >= 0 || rl >= 0));
    return lv - rv;
  }

};

Результат:

"0.1" - "1.0" = -1
"1.0" - "1.0" = 0
"1.0" - "1.0.0" = 0
"10" - "1.0" = 9
"3.7.6" - "3.7.11" = -5
"foobar" - "1.0" = -1

    }

Это очень просто, используя Maven:

import org.apache.maven.artifact.versioning.DefaultArtifactVersion;

DefaultArtifactVersion minVersion = new DefaultArtifactVersion("1.0.1");
DefaultArtifactVersion maxVersion = new DefaultArtifactVersion("1.10");

DefaultArtifactVersion version = new DefaultArtifactVersion("1.11");

if (version.compareTo(minVersion) < 0 || version.compareTo(maxVersion) > 0) {
    System.out.println("Sorry, your version is unsupported");
}

Вы можете получить правильную строку зависимостей для Maven Artifact с на этой странице :

<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-artifact</artifactId>
<version>3.0.3</version>
</dependency>

для моих проектов Я использую свою библиотеку commons-version https://github.com/raydac/commons-version , она содержит два вспомогательных класса - для разбора версии (анализируемая версия может быть сравнена с другой объект версии, потому что он сопоставим) и VersionValidator, который позволяет проверять версию для некоторого выражения, например !=ide-1.1.1,>idea-1.3.4-SNAPSHOT;<1.2.3

Для Scala вы можете использовать библиотеку, которую я создал: https://github.com/kypeli/sversion

Version("1.2") > Version("1.1")       // true
Version("1.2.1") > Version("1.1.2")   // true
Version("1.1.1") == Version("1.1.1")  // true
Version("1.1.1") > Version("1.1")     // true
Version("1.1.0") == Version("1.1")    // true
Version("1.1-RC2") > Version("1.1-RC1")  // true
Version("1.1-RC1") > Version("1.1")   // true

Вам нужно нормализовать строки версии, чтобы их можно было сравнить. Что-то вроде

import java.util.regex.Pattern;

public class Main {
    public static void main(String... args) {
        compare("1.0", "1.1");
        compare("1.0.1", "1.1");
        compare("1.9", "1.10");
        compare("1.a", "1.9");
    }

    private static void compare(String v1, String v2) {
        String s1 = normalisedVersion(v1);
        String s2 = normalisedVersion(v2);
        int cmp = s1.compareTo(s2);
        String cmpStr = cmp < 0 ? "<" : cmp > 0 ? ">" : "==";
        System.out.printf("'%s' %s '%s'%n", v1, cmpStr, v2);
    }

    public static String normalisedVersion(String version) {
        return normalisedVersion(version, ".", 4);
    }

    public static String normalisedVersion(String version, String sep, int maxWidth) {
        String[] split = Pattern.compile(sep, Pattern.LITERAL).split(version);
        StringBuilder sb = new StringBuilder();
        for (String s : split) {
            sb.append(String.format("%" + maxWidth + 's', s));
        }
        return sb.toString();
    }
}

Печатает

'1.0' < '1.1'
'1.0.1' < '1.1'
'1.9' < '1.10'
'1.a' > '1.9'

Я создал простую утилиту для сравнения версий на платформе Android с использованием соглашения Semantic Versioning . Поэтому он работает только для строк в формате X.Y.Z (Major.Minor.Patch), где X, Y и Z - целые неотрицательные числа. Вы можете найти его на моей GitHub .

Метод Version.compareVersions (String v1, String v2) сравнивает две строки версии. Он возвращает 0, если версии равны, 1, если версия v1 до версии v2, -1, если версия v1 находится после версии v2, -2, если формат версии недействителен.

Лучше всего использовать существующий код, возьмите преимущества Maven's ComparableVersion

:

• Apache License, версия 2.0,
• ,
• используется (скопировано) в нескольких проектах, таких как spring-security-core, jboss и т. д.
• несколько функций
• это уже java.lang.Comparable
• просто копировать-вставить, что один класс, никаких независимых сторон

Не включать зависимость от maven-артефакта как которые будут вытягивать различные транзитивные зависимости

Мне понравилась идея от @Peter Lawrey, и я расширил ее до дальнейших ограничений:

    /**
    * Normalize string array, 
    * Appends zeros if string from the array
    * has length smaller than the maxLen.
    **/
    private String normalize(String[] split, int maxLen){
        StringBuilder sb = new StringBuilder("");
        for(String s : split) {
            for(int i = 0; i<maxLen-s.length(); i++) sb.append('0');
            sb.append(s);
        }
        return sb.toString();
    }

    /**
    * Removes trailing zeros of the form '.00.0...00'
    * (and does not remove zeros from, say, '4.1.100')
    **/
    public String removeTrailingZeros(String s){
        int i = s.length()-1;
        int k = s.length()-1;
        while(i >= 0 && (s.charAt(i) == '.' || s.charAt(i) == '0')){
          if(s.charAt(i) == '.') k = i-1;
          i--;  
        } 
        return s.substring(0,k+1);
    }

    /**
    * Compares two versions(works for alphabets too),
    * Returns 1 if v1 > v2, returns 0 if v1 == v2,
    * and returns -1 if v1 < v2.
    **/
    public int compareVersion(String v1, String v2) {

        // Uncomment below two lines if for you, say, 4.1.0 is equal to 4.1
        // v1 = removeTrailingZeros(v1);
        // v2 = removeTrailingZeros(v2);

        String[] splitv1 = v1.split("\\.");
        String[] splitv2 = v2.split("\\.");
        int maxLen = 0;
        for(String str : splitv1) maxLen = Math.max(maxLen, str.length());
        for(String str : splitv2) maxLen = Math.max(maxLen, str.length());
        int cmp = normalize(splitv1, maxLen).compareTo(normalize(splitv2, maxLen));
        return cmp > 0 ? 1 : (cmp < 0 ? -1 : 0);
    }

Надеюсь, что это поможет кому-то. Он прошел все тестовые примеры в интервьювом и литовом коде (необходимо раскомментировать две строки в функции compareVersion).

Легко протестировано!

My java Solution

 public int compareVersion(String version1, String version2) {

    String[] first = version1.split("\\.");
    String[] second = version2.split("\\.");

    int len = first.length<=second.length? first.length:second.length;

    // the loop runs for whichever is the short version of two strings
    for(int i=0;i<len;i++){
      int firstInt = Integer.parseInt(first[i]);
      int secondInt = Integer.parseInt(second[i]);
        if(firstInt<secondInt){
            return -1;
        }
        else if(firstInt>secondInt){
            return 1;
        }
    }

    // below two condition check if the length are the not the same

    //if first string length is short then start from after first string length and compare it with second string value. second string value is not zero that means it is greater.
    if(first.length<second.length){
        for(int i=first.length;i<second.length;i++){
            int secondInt = Integer.parseInt(second[i]);
            if(secondInt!=0){
                return -1;
            }
        }
    }
    // similar logic as above just that first length is grater this time.
     else if(first.length>second.length){
        for(int i=second.length;i<first.length;i++){
            int firstInt = Integer.parseInt(first[i]);
            if(firstInt!=0){
                return 1;
            }
        }        
    }

    // return 0 if both string value is the same
    return 0;

}
