java while 循环 打印1到5的值

package com.fqs.test;

import java.util.Scanner;

public class hello {
    public static void main(String[] args) {
       //循环打印1到5
        int i=0;
        while(i<5){
            i++;
            System.out.print(i);

        }


    }
}

 先打印后  计数猜比较好理解

package com.fqs.test;

import java.util.Scanner;

public class hello {
    public static void main(String[] args) {
       //循环打印1到5
        int i=1;
        while(i<=5){

            System.out.print(i);
            i++;

        }


    }
}
