java - 如何将另一个类的变量调用到 ActionListener 方法中？

Question

我想提前道歉，我是java新手，不太了解，所以请跟着我。我想知道如何将我的角色属性从一个类中的一个 ActionListener 方法获取到另一个类中的另一个 ActionListener 方法。我想从用户那里获取有关一个类中的player1的输入，然后在另一个类中使用它们。请帮忙，非常感谢您的时间。

public void actionPerformed(ActionEvent event) {
    // TODO Auto-generated method stub

    if(event.getSource() == create){

        Character player1 = new Character( Integer.parseInt(strength.getText()), Integer.parseInt(defense.getText()), Integer.parseInt(health.getText()) , Integer.parseInt(dexterity.getText()));
        player1.name = name.getText();

        JOptionPane.showMessageDialog(this, "\nName: " + player1.name + "\nHealth: " + player1.health + "\nStrength: " + player1.strength + "\nDefense: " + player1.defense + "\nDexterity: " + player1.dexterity);
        dispose();//To close the current window

       GameWindow gwindow = new GameWindow();
        gwindow.setVisible(true);//Open the new window
    }

放入

@Override
public void actionPerformed(ActionEvent event) {

    Object source = event.getSource();
    Character Goblin = new Character(10, 3, 6, 10);
    Character Witch = new Character(2, 7, 3, 20);
    Character Zombie = new Character(5, 5, 5, 15);
    int damage;

    if (event.getSource() == right) {

        label1.setText("You have encountered a goblin!");
        label2.setText("Do you wish to fight or flee?");
        fight.setVisible(true);
        flee.setVisible(true);
    }

        if(event.getSource() == fight) {

            System.out.println(player1 + " VS. " + Goblin.name);

            while(player1.isAlive() && Goblin.isAlive()){

                // player 1 attack
                damage = player1.attack(Goblin);
                System.out.println(player1.name + " hits " + Goblin.name + " for " + damage + " damage.");

                // player 2 attack
                damage = Goblin.attack(player1);
                System.out.println(Goblin.name + " hits " + player1.name + " for " + damage + " damage.\n");
            }

            // Check to see who won
            if( player1.isAlive()){
                System.out.println(player1.name + " wins!");
            }
            else{
                System.out.println("You have perished");
            }

        }
}

将 Player1 声明为公共(public)静态成员所以它的值不能改变。

并且您可以通过该特定类的对象使用player1。

    Class First{
          //Declare That Character object as a static public here
          //Player1;
           }
    Class Second{
          //First Create Object Of that class....
          First f = new First(//Parameter For Constructor);
          f.Player1;

           }
