do....while 与while 的区别

while 先判断后执行,do while是先执行后判断

do while 总是保证循环体会被至少执行一次

public static void main(String[] args) {
       int a =0;
       while (a <0){
           System.out.println(a);
           a++;
      }
       System.out.println("+++++++++++++++++++++++");
       do {
           System.out.println(a);
           a++;
      } while (a<0);
  }
