For循环打印九九乘法表

打印九九乘法表

public class Demo02 {
    public static void main(String[] args) {
        //打印九九乘法表
        for (int i = 1; i <= 9; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print(i+"*"+j+"="+i*j+"\t");
            }
            System.out.println();
        }
    }
}

增强For循环

public static void main(String[] args) {
    int[] nums = {10,20,30,40,50};

    //增强for循环
    for (int x:nums){
        System.out.println(x);
    }
}
