流程控制语句2

1.循环语句do…while

do {
执行语句
………
} while(循环条件);

用do.....while打印1-100

int i=1;
do{
     System.out.println(i);
     i++;
    }while(i<=100);

用do.....while算1-100的和

int i=0;
int count=0;
do{
    count+=i;
    i++;
 }while(i<=100);
    System.out.println(count);

用do....while算1-100的偶数和

int i=0;
int count=0;
do{
  if(i%2==0){
    count+=i;
}
    i++;
}while(i<=100);
    System.out.println(count);
