這是一個相當基本的問題 我正在製作一個遊戲，其中會有兩個玩家。遊戲開始於主菜單，玩家可以選擇開始遊戲，輸入玩家詳細信息或退出。如何使用任何函數中的返回值
2個函數分別輸入兩個玩家的名字（因爲一個函數只能返回值），並將這兩個值返回到遊戲的主菜單，在整個遊戲中使用這個名稱。這是我的代碼到目前爲止：
import java.io.*;
class AQADO
{
InputStreamReader isr = new InputStreamReader (System.in);
BufferedReader br = new BufferedReader (isr);
String Player1,Player2;
void main()throws IOException
{
System.out.println("--------------------------------------------------------------AQADO DICE GAME--------------------------------------------------------------\n\n\n");
MainMenu();
}
void MainMenu()throws IOException
{
System.out.println("Please enter your choice\n\n");
System.out.println("1. Enter Player Names");
System.out.println("2. Play Game");
System.out.println("3. Quit\n");
String MenuChoice = br.readLine();
if(MenuChoice.equals("1"))
{
Player1Details();
System.out.println("\nPlayer 1, you are called " + Player1 + "\n");
Player2Details();
System.out.println("\nPlayer 2, you are called " + Player2 + "\n\n");
MainMenu();
}
else if (MenuChoice.equals("2"))
{
GameExe();
}
else if (MenuChoice.equals("3"))
{
System.out.println("----------------------------------------------------------THE END---------------------------------------------------------");
}
else
{
System.out.println("\n\nSorry, couldn't get that.....\n\n");
MainMenu();
}
}
String Player1Details()throws IOException
{
System.out.println("Player 1, please enter your name....\n");
String Player1 = br.readLine();
if (Player1.equals(""))
{
Player1 = "Player 1";
}
return Player1;
}
String Player2Details()throws IOException
{
System.out.println("Player 2, please enter your name....\n");
String Player2 = br.readLine();
if (Player2.equals(""))
{
Player2 = "Player 2";
}
return Player2;
}
你能幫助我，因爲兩個玩家的名字都被返回爲'null'。
