while语句示例：
public class Demo01 {
    public static void main(String[] args) {
        //while
        int i=0;
        int sum=0;
        while (i<=100){
            i++;
            sum+=i;

            System.out.println(sum);
        }


    }
}

do while语句示例：

import java.util.Scanner;

public class Demo02 {
    public static void main(String[] args) {
        //do while
        int i=0;
        int sum=0;
        do {
            sum+=i;
            i++;
        }
        while (i<=100);
            System.out.println(sum);
