Согласно вашему коду:
String[] name = {"tom", "dick", "harry"};
for(int i = 0; i<=name.length; i++) {
System.out.print(name[i] +'\n');
}
Если вы проверите System.out.print (name.length),
, вы получите 3;
, что означает, что длина вашего имени равна 3
, ваш цикл работает от 0 до 3, который должен работать либо от «0 до 2», либо от «1 до 3»
Ответ
String[] name = {"tom", "dick", "harry"};
for(int i = 0; i<name.length; i++) {
System.out.print(name[i] +'\n');
}
