我正在尝试制作一个返回程序，该程序将在单击鼠标左键时按回车键...

由 http://www.java-tips.org/java-se-tips/java.awt/how-to-use-robot-class-in-java.html（用于 void 输入方法）和“thenewboston”提供我到目前为止...

我正在尝试让它在其他平台上运行，例如：Word、Note Pad 而不仅仅是在 JFrame 上

这是我到现在为止的...

import java.awt.event.MouseEvent;
import javax.swing.*;
   import java.awt.*;
   import java.awt.event.*;

import java.awt.Robot;
import java.awt.event.KeyEvent;


public class MW3Tool

{

public static void main (String[] args)

{

Robot enter = new Robot();
int num;
return count = 0;

num = count * 3;


Control c = new Control();

for (int k = 1; k <= num; k++)


{System.out.println("H");}


/*  try {
Robot robot = new Robot();                    // Going to be used to electronically hit the enter key later.

  robot.delay(5000);
  robot.setSpeed(10);
  for (int k = 1; k<= num; k ++)
    robot.keyPress(KeyEvent.VK_ENTER);

 }           
  catch (AWTException e) {
   e.printStackTrace();

         }   }    */

}

private class Control implements MouseListener


{
int count;
int useless;
int useless2;
   public void mouseClicked(MouseEvent event) 
{
   count++;
}

public void mousePressed(MouseEvent event) 
{
   useless++;
}


public void mouseExited(MouseEvent event) 
{
   useless2++;
}

}

}

我的错误：

 ----jGRASP exec: javac -g MW3Tool.java

MW3Tool.java:20: cannot return a value from method whose result type is void
return count = 0;
             ^
MW3Tool.java:22: cannot find symbol

      ^

            ^
MW3Tool.java:60: MW3Tool.Control is not abstract and does not override abstract method mouseEntered(java.awt.event.MouseEvent) in java.awt.event.MouseListener
private class Control implements MouseListener
        ^
4 errors

 ----jGRASP wedge2: exit code for process is 1.
 ----jGRASP: operation complete.

对不起我的低效方法（新加入Java）

任何帮助将不胜感激...谢谢...

第一个错误：您是否尝试初始化整数？语法错误。利用

int count = 0;

第二个错误：解决第一个错误将解决此错误。
第三个错误：而不是说

private class Control implements MouseListener { ... }

说

private static class Control implements MouseListener { ... }

最后一个错误：请参阅 MouseListener Javadocs：方法摘要
void mouseClicked(MouseEvent e) 在组件上单击（按下和释放）鼠标按钮时调用。
void mouseEntered(MouseEvent e) 当鼠标进入组件时调用。
void mouseExited(MouseEvent e) 当鼠标退出组件时调用。
void mousePressed(MouseEvent e) 在组件上按下鼠标按钮时调用。
void mouseReleased(MouseEvent e) 在组件上释放鼠标按钮时调用。
您必须重写 Control 类中的所有这些方法，您的程序才能工作。
希望这可以帮助！
