新手请教java程序怎么修改成循环

新手刚开始接触JAVA，写的一个小程序，程序对的是，想修改成能重复运行的循环体不知道怎么改，求教。
源程序如下
import java.util.*;
public class Goodminging {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
int a,b,c;
a=(int)(Math.random()*9)+1;
b=(int)(Math.random()*9)+1;
System.out.println(a+"x"+b+"=?");
c=sc.nextInt();
if (c==a*b)System.out.println("答对了");
else System.out.println("答错了");
}
}
运行后不管打对了还是错了，只一次就结束了，想改成对了就继续答题，打错了修改答案后继续答题的程序，谢谢大神了

Answer 1

import java.util.*;
public class Goodminging {
 public static void main(String[] args) {
  while(true){
  Scanner sc=new Scanner(System.in);  
  int a,b,c;    
  a=(int)(Math.random()*9)+1;  
  b=(int)(Math.random()*9)+1;  
  while(true){
  System.out.println(a+"x"+b+"=?");  
  c=sc.nextInt();      
  if (c==a*b) {System.out.println("答对了"); break;}
  else {System.out.println("答错了\n请重新回答");
  }  
  }
  }
 }
 }

Answer 2

import java.util.*;
public class Test3 {
public static void main(String[] args) {
int a , b , c;
boolean going = false;

do {
Scanner sc = new Scanner(System.in);
a = (int)(Math.random() * 9) + 1;
b = (int)(Math.random() * 9) + 1;
System.out.println(a + "x" + b + "=?");
c = sc.nextInt();

while(c != a * b) {
System.out.println("答错了,请再次输入");
sc = new Scanner(System.in);
c = sc.nextInt();
}

System.out.println("答对了");
System.out.println("是否继续？(继续请输入1)");
sc = new Scanner(System.in);

if (sc.nextInt() == 1)
going = true;
else {
going = false;
}

}while(going);

System.out.println("Game Over!");
}
}
