Java 程序需要循环X次,无论输入多少都只运行一次。没有抛出错误
程序需要运行Dice.java,无论用户输入多少次,都只运行一次,不会抛出错误。我也不能证明什么,但感觉输出有一个模式 每样东西都试了一点 DiceGame1.java-充当主循环,获取用户希望一次掷多少骰子,并处理主循环Java 程序需要循环X次,无论输入多少都只运行一次。没有抛出错误,java,Java,程序需要运行Dice.java,无论用户输入多少次,都只运行一次,不会抛出错误。我也不能证明什么,但感觉输出有一个模式 每样东西都试了一点 DiceGame1.java-充当主循环,获取用户希望一次掷多少骰子,并处理主循环 import java.util.Scanner; public class DiceGame1 { public static int mainloop; public static void main(String [] args) {

java-旨在让DieGame1.java运行无止境循环多长时间
import java.util.Scanner;
public class RunAgain
{
public static void RunAgain()
{
String userinput;
Scanner keyboard = new Scanner(System.in);
System.out.print("Run again? Y/N: ");
userinput = keyboard.nextLine();
if (userinput.equals ("Y"))
{
System.out.println("======================================");
}
else
{
keyboard.close();
System.exit(0);
}
}
}
在文件DiceGame1.java中,在这段代码中
//Create a for loop that will run X amount of times
for(int i =0; i< VAR_HOWMANY; i++)
{
Dice.RollDie();
RunAgain.RunAgain();
}
编辑:也可以修改您切换到以下内容:
// Prints out the generated number
switch (randomInteger)
{
case 1:
System.out.println("1");
break;
case 2:
System.out.println("2");
break;
case 3:
System.out.println("3");
break;
case 4:
System.out.println("4");
break;
case 5:
System.out.println("5");
break;
case 6:
System.out.println("6");
break;
}
您在错误的位置调用runreach(),并且在开关状态中每次使用case
后都没有使用break
这就是它的工作原理:

while (mainloop < 1)
{
//Create a for loop that will run X amount of times
for(int i =0; i < VAR_HOWMANY; i++)
{
Dice.RollDie();
}
RunAgain.RunAgain();
}
}
}

// Prints out the generated number

即使开关状态不一定正确,他也没有在使用案例后使用break@戴夫:你需要在你的案件陈述中逐一说明。看看我编辑过的答案。我已经测试过了,它现在可以工作了。但这并不能完全解决它,当你接受再次运行时,它会滚动你每次最初输入的骰子数。每次都需要提示。
