小峰视频十:循环while、for

public class demo013 {

	public static void main(String[] args) {
		// while 循环语句
		int i=1;
		while (i<=10) {
			System.out.println(i+" ");	
			i++;
		}
		System.out.println("===============");
		//do...while循环语句
		int j=1;
		do {
			System.out.println(j+" ");
			j++;
		} while (j<=10);
		
		System.out.println("===============");
		//for 循环
		for(int k=1;k<=10;k++) {
			System.out.println(k+" ");
		}
		
		//for循环的嵌套
		for(int m=0;m<10;m++) {
			for(int n=0;n<10;n++) {
				System.out.print("m="+m+",n="+n+" ");
			}
			System.out.println();
		}
		
		//打印所有的水仙花数(一个三位数,各位数的立方和等于改本身)
		
		for(int s=100;s<=999;s++) {
			int x=s/100;
			int y=(s-x*100)/10;
			int z=s-x*100-y*10;
			if(s == x*x*x+y*y*y+z*z*z) {
				System.out.println(s+" ");
			}
		}
		
		//打印九九乘法表
		for(int a=1;a<10;a++) {
			for(int b=1;b<=a;b++) {
				System.out.print(b+"x"+a+"="+a*b+" ");
