java 是否继续操作？代码

Scanner input = new Scanner(System.in);


do{
System.out.print("是否继续？y/n：");

}while(input.next().charAt(0)=='y');

-------------------------------------------------------

案例：

import java.util.Scanner;
class hg1
{ 
public static void main(String[] args){
Scanner input = new Scanner(System.in);
do{
System.out.print("请输入减数：");
int one = input.nextInt();
System.out.print("请输入被减数：");
int two = input.nextInt();
System.out.print("请输入答案：");
int theer = input.nextInt();
System.out.println("正在进行判断，请稍等。");
if(theer==one-two){
System.out.println("结果：对！;答案是： "+one+"-"+two+"="+(one-two));
}
else if(theer!=one-two){
System.out.println("结果：错！;答案是："+one+"-"+two+"="+(one-two));
}
System.out.print("是否继续？y/n：");
}
while(input.next().charAt(0)=='y');
}
}
