遍历字符串数组

public class Test9 {
    public static void main(String[] args) {
        String[] strings = new String[5];
        strings[0] = "刘";
        strings[1] = "关";
        strings[2] = "张";

        // 遍历
        for(int i=0;i<strings.length;i++){
            String item = strings[i];
            System.out.println(item);
        }
    }
}

遍历整数数组

// 有默认值的数组定义完成
int[] ints = {33, 44, 55};
// 遍历这个数组
for (int i = 0; i < ints.length; i++) {
    System.out.println(ints[i]);
}
