如何在JLabel或JEditorPane中指定选择

import javax.swing.*;

public class LabelSelectionExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Label Selection Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        JLabel label = new JLabel("This is a JLabel with selectable text.");
        label.setBounds(50, 50, 300, 30);
        
        // 指定选择的起始位置和结束位置
        label.setSelectionStart(5);
        label.setSelectionEnd(15);
        
        // 确保组件获取焦点
        label.requestFocus();
        
        frame.add(label);
        frame.setSize(400, 200);
        frame.setLayout(null);
        frame.setVisible(true);
    }
}
