Java的GUL编程中使用JButton的子类实现统一风格的按钮

package cn.menu.button;

import java.awt.Color;
import java.awt.Font;
import java.awt.Insets;

import javax.swing.JButton;

public class MenuButton extends JButton {

/**
*
*/
private static final long serialVersionUID = 1L;

private Font font = new Font("楷体", Font.PLAIN, 35);

public MenuButton(String name) {

super(name);

this.setFont(font);
this.setBackground(Color.WHITE);
this.setMargin(new Insets(9, 9, 9, 9));
}

public void asd() {

}

public int asd(int a) {
return a;

}
}
