Java 如何要求用户继续？
我已经做了这个代码，一切正常，但我希望用户按下回车键继续滚动，直到他们赢或输。任何建议都很好Java 如何要求用户继续？,java,loops,Java,Loops,我已经做了这个代码，一切正常，但我希望用户按下回车键继续滚动，直到他们赢或输。任何建议都很好 import hsa.Console; import java.util.Scanner; // Needed for the Scanner class import java.util.Random; public class Craps_Final1 { static Console c; public static void main(String [] args)

在java中，您应该使用
扫描器。您可以在这里看到如何使用它我想说的是，与其让代码嵌入main，不如让它在另一个方法中使用，在该方法的末尾，您询问用户是否希望再次播放，如果是，则该方法再次递归调用自身，如果不是，则程序终止，因此您可以在main中调用它
public static void play()
{
//place code here
S.o.p("play again?");
//if yes call itself to startover
play();
//if no, program terminates
}
那么，大体上，您只有一个方法调用
public static void main(String...args)
{
play();
}
这是我的建议
编辑：为了避免堆叠流，我提供了一个替代方案
public static void play()
{
//place code here
}
public boolean playAgain(int choice)
{
if(!choice==1)
return false;
Return true;
}
public staic void main(String...args)
{
int repeat =0;
do
{
play();
S.o.p("play again?\n enter 1 for yes,0 for no");
//assign repeat the number choice
}while(playAgain(repeat));
}
注意：代码假定用户输入正确。不要将内容标记为C和Java。。。它们确实不同。请正确命名变量，而不是添加注释。所以不是int点；//掷骰子
使用int骰子
。（骰子的复数形式是“骰子”。单数形式是“骰子”）。根据这一建议，如果用户继续玩得足够频繁，你会得到堆栈溢出…是的，但通常需要大约上千次，或者避免他在主循环中使用while循环：
