java流程控制之 while 循環 1到100的和

package struct;

public class Demo03 {
    public static void main(String[] args) {
        text();
        System.out.println("------------");
        text2();
    }

    public static void text() {
        int i = 0;
        while (i < 100) {
            i++;
            System.out.println(i);
        }
    }

    public  static  void  text2(){
        int i=0;
        int sum=0;

        while (i<=100){
            sum+=i;
            i++;

        }
        System.out.println(sum);
    }
