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!       ");
