Java 当循环在末尾到达continue语句时，它不会'；不要从顶部重新启动

好的，我创建了以下程序。它尚未完成，但当代码结束时（y或n部分），用户决定再试一次，他们没有选择输入新赌注，它只使用第一次输入的赌注

（如果您需要了解代码方面的帮助或认为其他人可能难以理解，请发表评论）

import java.util.*；
公共类Lab15{
静态扫描仪kin=新扫描仪（System.in）；
公共静态void main（字符串[]args）{
双倍货币=1000；
System.out.println（“欢迎你从1000美元开始玩垃圾游戏！”）；
int play=1；//用于取消整个循环的变量
char yesNo；//如果用户想继续播放或不继续播放
而（金钱>0&&play==1）{
System.out.print（“请输入您想下注的金额：”）；
双倍赌注=kin.nextDouble（）；
而（（下注0））{
进行{//循环以测试下注是否合法
如果（钱金钱| |赌注<0）；
金钱=赌注；
System.out.println（“您有下注$”+下注+”和“+剩下的钱+”）；
intdie1=（1+（int）（6*Math.random（））；
intdie2=（1+（int）（3*Math.random（））；
整数和=die1+die2；
System.out.println（“您滚动了“+die1+”和“+die2+”，总计“+sum”）；
System.out.print（“您想再次播放（y）还是不播放（n）”；
yesNo=kin.next（）.charAt（0）；
int loopBreak=0；//在循环吼叫时中断do
做{
如果（yesNo=='y'）{//取上面的是否以重新启动循环
System.out.println（“重新启动…”）；
loopBreak+=1；
继续；
}
else if（yesNo=='n'）{
System.out.println（“感谢您的参与”）；
play-=1；//取消整个程序
打破
}
否则{
System.out.println（“请输入'y'或'n'”）；
}
}而（loopBreak==0）；
如果（播放==0）{
打破
}
}
}
}
}

这一切都是关于嵌套while循环的，它不会在需要时停止。是这样的

 while(money > 0 && play == 1) {
     System.out.print("Please Enter The Amount You Want To Bet: ");
     double bet = kin.nextDouble();
     while((bet <= money || bet > 0)) {

         ...

         do {
             if(yesNo == 'y') { //take above yes no to restart loop or not
                 System.out.println("Restarting...");
                 loopBreak += 1;
                 continue;
             }
             else if(yesNo == 'n') {
                 System.out.println("Thank You For Playing");
                 play -= 1; //to cancel whole program
                 break;
             }
             else {
                 System.out.println("Please Enter 'y' Or 'n'");
             }
         } while(loopBreak == 0);

         if(play == 0) {
             break;
         }
     }
 }

部分。无论如何，更正的代码在这里（我尝试了所有的可能性，它工作了）

公共静态void main（字符串[]args）{

而（金钱>0&&play==1）{
System.out.print（“请输入您想下注的金额：”）；

而（（下注0））{
进行{//循环以测试下注是否合法
如果（钱金钱| |赌注<0）；
金钱=赌注；
System.out.println（“您有下注$”+下注+”和“+剩下的钱+”）；
intdie1=（1+（int）（6*Math.random（））；
intdie2=（1+（int）（3*Math.random（））；
整数和=die1+die2；
System.out.println（“您滚动了“+die1+”和“+die2+”，总计“+sum”）；
System.out.print（“您想再次播放（y）还是不播放（n）：”；
yesNo=kin.next（）.charAt（0）；
int loopBreak=0；//在循环吼叫时中断do
做{
如果（yesNo=='y'）{//取上面的是否以重新启动循环
System.out.println（“重新启动…”）；
loopBreak++；
继续；
}
else if（yesNo=='n'）{
System.out.println（“感谢您的参与”）；
播放--；//取消整个程序
打破
}
否则{
System.out.println（“请输入'y'或'n'：”；
}
}而（loopBreak==0）；
如果（播放==0 | |循环中断==1）{
打破
}
}
}
}
}

祝你有愉快的一天

另一种解决方案是使用标记的中断/继续

但是，应该谨慎使用（或者根本不使用）。你也许可以用其他的方法来简化它
