java通过复选框控件数组实现添加多个复选框控件示例分享

思路如下：

创建jpanel面板对象；
使用jpanel类的setlayout(0,4)方法设置网格布局管理器，即列数为4，行数自动调节；
创建一个字符串型一维数组作为控件文本数组；
创建一个jcheckbox型一维数组作为控件数组；
使用for循环遍历控件数组，初始化数组中的复选框组件，使用jpanel类的add()方法把数组元素（即每个复选框）添加到面板中。
代码如下：

package cn.edu.xidian.crytoll;

import java.awt.borderlayout;
import java.awt.eventqueue;
import java.awt.gridlayout;

import javax.swing.jcheckbox;
import javax.swing.jframe;
import javax.swing.jpanel;
import javax.swing.border.emptyborder;
import javax.swing.jlabel;
import javax.swing.uimanager;

public class checkboxarray extends jframe {

    /**
     *
     */
    private static final long serialversionuid = -5338362310060106193l;
    private jpanel contentpane;
    private jpanel panel;

    /**
     * launch the application.
     */
    public static void main(string[] args) {
        try {
            uimanager
                    .setlookandfeel("com.sun.java.swing.plaf.nimbus.nimbuslookandfeel");
        } catch (throwable e) {
            e.printstacktrace();
        }
        eventqueue.invokelater(new runnable() {
            public void run() {
                try {
                    checkboxarray frame = new checkboxarray();
                    frame.setvisible(true);
                } catch (exception e) {
                    e.printstacktrace();
                }
            }
        });
    }

    /**
     * create the frame.
     */
    public checkboxarray() {
        settitle("通过复选框控件数组实现添加多个复选框控件");
        setdefaultcloseoperation(jframe.exit_on_close);
        setbounds(100, 100, 409, 331);
        contentpane = new jpanel();
        contentpane.setborder(new emptyborder(5, 5, 5, 5));
        contentpane.setlayout(new borderlayout(0, 0));
        setcontentpane(contentpane);

        jlabel label = new jlabel(
                "你的爱好有哪些：");
        contentpane.add(label, borderlayout.north);
        contentpane.add(getpanel(), borderlayout.center);
    }

    private jpanel getpanel() {
        if (panel == null) {
            panel = new jpanel();// 创建面板对象
            panel.setlayout(new gridlayout(0, 4));// 设置网格布局管理器
            // 创建控件文本数组
            string[] labels = { "足球", "篮球", "魔术", "乒乓球", "看电影", "魔兽世界", "cs战队",
                    "羽毛球", "游泳", "旅游", "爬山", "唱歌", "写博客", "动物世界", "拍照", "弹吉他",
                    "读报纸", "飙车", "逛街", "逛商场", "麻将", "看书", "上网看资料", "新闻", "军事",
                    "八卦", "养生", "饮茶" };
            jcheckbox[] boxs = new jcheckbox[labels.length];// 创建控件数组
            for (int i = 0; i < boxs.length; i++) {// 遍历控件数组
                boxs[i] = new jcheckbox(labels[i]);// 初始化数组中的复选框组件
                panel.add(boxs[i]);// 把数组元素（即每个复选框）添加到面板中
            }
        }
        return panel;
    }
}
