java - 如果用户输入错误答案，如何跳回到 if 语句的开头

Question

代码如下:

if (g1 == 6) {
   System.out.println("Correct! Proceed to the next challenge");
} 
else {  
   System.out.println("That is incorrect, please try again");
}

如果他们输入“4”作为他们的猜测，我如何允许他们重试？基本上，我如何返回到 if 语句的开头？

Answer 1

String g1 = "";
try {
    InputStreamReader converter = new InputStreamReader(System.in);
BufferedReader in = new BufferedReader(converter);
    do {
      g1 = in.readLine();
      if (g1 == 6) {
        System.out.println("Correct! Proceed to the next challenge");
      } else {
        System.out.println("That is incorrect, please try again");
      }
    } while(g1 != 6);
} catch (Exception e) {
System.out.println("Error! Exception: "+e); 
}
