双输出程序

当我运行我的代码时，我得到了输出两次而不是一次。这是什么原因？另外我怎样才能输出计算机猜测这个单词的次数呢？这是当前的输出：但是当我输入一个单词时，它会输出两次？双输出程序

Enter a 4 or 5 letter word and the computer will play hangman against you! 
nice 
Your word is: nice 
Enter a 4 or 5 letter word and the computer will play hangman against you!

代码

import java.util.Scanner; 
import javax.swing.JApplet; 
import java.awt.*; 

public class Hangman extends JApplet 
{ 
    public void paint (Graphics Page) 
    { 
       //gallows 
       Page.drawLine(0,300,20,300); 
       Page.drawLine(10,40,10,300); 
       Page.drawLine(10,40,80,40); 
       Page.drawLine(80,40,80,55); 

       //torso 
       Page.drawOval(50,55,50,55); 
       Page.drawOval(50,100,50,100); 
       //left arm and hand 
       Page.drawLine(50,150,40,110); 
       Page.drawLine(40,110, 45,100); 
       Page.drawLine(40,110, 25,100); 
       Page.drawLine(40,110, 25,115); 


       //right arm and hand 
       Page.drawLine(100,150,120,110); 
       Page.drawLine(120,110, 115,95); 
       Page.drawLine(120,110, 125,95); 
       Page.drawLine(120,110, 135,115); 

       //left leg and foot 
       Page.drawLine(80,200,100,250); 
       Page.drawLine(100,250, 115,260); 


       //right leg and foot 
       Page.drawLine(75,200,60,250); 
       Page.drawLine(60,250,45,260); 




    Scanner in = new Scanner(System.in); 
    System.out.println("Enter a 4 or 5 letter word and the computer will play hangman against you!"); 



    String word = in.nextLine(); 




    char[] letter = word.toCharArray(); 


    for (int i = 0; i < letter.length; i++) { 
      letter[i] = 'a'; 
    } 


    for (int i = 0; i < word.length(); i++){ 
     for (int j = 48; j < 122; j++) { 

        if (letter[i] == word.charAt(i)) { 
          break; 
        } else { 
          letter[i] = (char)((int) j + 1); 
        } 
      } 
    } 
    System.out.println("Your word is: "); 

    for (char letters : letter) { 
      System.out.print(letters); 
    } 

} 

}

与'JApplets'如何调用其'paint'方法有关。不要在那里做输入。 –

我该如何解决这个问题？ – user3112609

不知怎的，你的'paint'方法调用两次。简单的解决方案使另一个类/方法进行输入。 –
