如何通过循环输出数组

public class F {
    public static void main(String[] args) {
        int[] num = new int[]{11,55,99,88,77};
        for(int i =0;i<num.length;i++)
        {
            System.out.println(num[i]);
        }
    }
}

public class Welcome {
    public static void main(String[] args){
        String[] runoobs = new String[3];
        runoobs[0] = "教程";
        runoobs[1] = "工具";
        runoobs[2] = "笔记";
        for (int i = 0; i < runoobs.length; i++){
            System.out.println(runoobs[i]);
        }
    }
}

以上代码运行输出结果为：

教程
工具
笔记
