数组的遍历 - JAVA学习网

数组的遍历:

class Hello2 {
    public static void main(String[] args) {
        int[] arr = {11,12,13,14,15};
        for (int i = 0;i < arr.length ;i++ )
        {
            System.out.println(arr[i]);
        }
    }
}

结果:

用方法来实现数组的遍历:

class Hello2 {
    public static void main(String[] args) {
        int[] arr1 = {11,12,13,14,15};
        print(arr1);
        
    }
    public static void print(int[] arr) {
        for (int i = 0;i < arr.length ;i++ )
        {
            System.out.print(arr[i] + " ");
        }
    }

}

结果:
