当数字超过 100 时，如何解决数字的 jlabel 问题？

Question

我做了一些简单的游戏，比如 cookie clicker。它可以正常工作，但问题是当点数超过 100 时我无法正确看到它们。我将在下面留下整个代码。出于某种原因，我让它变得有点复杂，但现在我遇到的唯一问题是 jLabel ...

所以我希望有人能帮助我。

package javaapplication17;

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

import javax.*;

public class JavaApplication17 {

    public static void main(String[] args) {

        DBP prozor = new DBP();

        prozor.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

        prozor.setVisible(true);

        prozor.setLocation(600, 250);

        prozor.setLayout(null);

    }

}

class DBP extends JFrame{

        private JLabel oznaka;

        private int brojac;

        private boolean upgraded1;

        private boolean upgraded2;

        private boolean upgraded3;

        private boolean isup1;

        private boolean isup2;

        private boolean isup3;

        public DBP(){

            setTitle("Cookie Clicker");

            setSize(800, 480);

            setLayout (new FlowLayout(FlowLayout.CENTER, 30, 20));

            oznaka = new JLabel("No points!");

            add(oznaka);

            JButton dugme = new JButton("Click");

            add(dugme);

            JButton upgrade = new JButton("Buy first upgrade!");

            upgrade.setBounds(317, 50, 150, 50);

            add(upgrade);

            upgrade.setVisible(false);

            JButton upgrade2 = new JButton("Buy second upgrade!");

            upgrade2.setBounds(317, 100, 150, 50);

            add(upgrade2);

            upgrade2.setVisible(false);

            JButton upgrade3 = new JButton("Buy third upgrade!");

            upgrade3.setBounds(317, 150, 150, 50);

            add(upgrade3);

            upgrade3.setVisible(false);

    

            dugme.addActionListener(new ActionListener(){

            public void actionPerformed(ActionEvent e){

                brojac++;

                if(upgraded1){

                    isup1 = true;

                }

                if(upgraded2){

                    isup2 = true;

                }

Answer 1

要么设置一个首选尺寸：oznaka.setPreferredSize(new Dimension(100, 20));或者将初始文本设置得足够大（附加空格）：oznaka = new JLabel("No points!       ");
