Java学习基础-while结构

while结构

package com.struct;
//while循环
public class WhileDemo01 {
    public static void main(String[] args) {
        //输出1~100
        int i = 0;

        while (i<100){
            i++;
            System.out.println(i);
        }
    }
}

package com.struct;

public class WhileDemo02 {
    public static void main(String[] args) {
        //计算 1+2+3+...+100=？
        int i = 0;
        int sum = 0;

        while (i<=100){
            sum = sum + i;
            i++;
        }
        System.out.println(sum);
    }
}
