java創(chuàng)建窗體時(shí)，兩個(gè)文本輸入框一個(gè)出錯(cuò)鋪滿了整個(gè)窗口，代碼如下，請(qǐng)高人指點(diǎn)

JFrame的默認(rèn)布局管理器是BorderLayout，有五個(gè)方向，TOP、LEFT、CENTER、RIGHT、BOTTOM，如果不給控件制定方向的話會(huì)都繪制到同一個(gè)默認(rèn)方向CENTER，所以你最后添加的jf2把之前添加的組件都覆蓋了，為每個(gè)組件指定方向即可。建議使用JPanel，使用FlowLayout。

java圖形界面的布局

沒(méi)用過(guò)SWT的人路過(guò)，提供一個(gè)SWING：

窗口用JFrame(frame)，布局為BorderLayout.

頂部為JLabel(labelTop),帶圖片和文字，用frame.add(labelTop, BorderLayout.NORTH)加入

左面為JPanel(panelLeft),布局為BoxLayout，參數(shù)Y_AXIS.需要在創(chuàng)建JPanel時(shí)設(shè)置Layout為NULL，然后再創(chuàng)建BoxLayout時(shí)需要把已經(jīng)建立的panelLeft作為參數(shù)傳進(jìn)去，然后再設(shè)置panelLeft的Layout為那個(gè)BoxLayout。用frame.add(panelLeft, BorderLayout.WEST)加入

中間為一堆不同功能的JPanel,布局根據(jù)功能而定了，在點(diǎn)擊按鈕時(shí)，移除frame此時(shí)中間的panel（記錄在一個(gè)自己的變量panelCenter里），然后加入按鈕對(duì)應(yīng)的panel，再把加入的panel存入變量panelCenter.

用java做一個(gè)窗口

java做窗口的話，需要用swing技術(shù)，之后創(chuàng)建JFrame 等組件，即可完成窗口創(chuàng)建工作。

package inter.frame;import java.awt.BorderLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;public class MenuTest { /**

* @param args

*/

JFrame frame; //定義一個(gè)窗口架構(gòu)

JMenuBar mb;//定義窗口的菜單工具欄

JMenu m; //定義菜單

JMenuItem mi1;//定義菜單的內(nèi)容

JMenuItem mi2; //定義菜單的內(nèi)容

public MenuTest() {

initFrame();

initAction();

}

public void initFrame() {

frame = new JFrame();

mb = new JMenuBar();

m = new JMenu("學(xué)生查詢(xún)");

mi1 = new JMenuItem("確認(rèn)");

mi2 = new JMenuItem("取消"); m.add(mi1);

m.add(mi2);

mb.add(m);

frame.add(mb, BorderLayout.NORTH);

frame.setSize(300, 300); //設(shè)置窗口大小

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//設(shè)置退出時(shí)關(guān)閉窗口

frame.setVisible(true);//設(shè)置窗口可見(jiàn)

} public void initAction() {

mi1.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

// 具體實(shí)現(xiàn)代碼根據(jù)實(shí)際要求填寫(xiě)

System.out.println("click");

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了確定按鈕");

}

});

mi2.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

// 具體實(shí)現(xiàn)代碼根據(jù)實(shí)際要求填寫(xiě)

JOptionPane.showMessageDialog(null, "你點(diǎn)擊了取消按鈕");

}

});

} public static void main(String[] args) {

new MenuTest();//執(zhí)行菜單創(chuàng)建

}}

Java中怎么新建窗口？我是新手麻煩代碼中主要語(yǔ)句解釋一下

不知道是不是你說(shuō)的窗口

使用javaswing JFrame設(shè)計(jì)窗口 + 布局就可實(shí)現(xiàn)，，如下例（添加了詳細(xì)注釋?zhuān)?/p>

import java.awt.BorderLayout;

import java.awt.Container;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JTextArea;

public class JFrameTest extends JFrame implements ActionListener {

private static final long serialVersionUID = -2829899643559384548L;

private JButton b1 = null;//按鈕

private JTextArea jta = null;//文本

public JFrameTest() {

Container c = this.getContentPane();

c.setLayout(new BorderLayout());//設(shè)置布局方式，BorderLayout東西南北中布局

b1 = new JButton("點(diǎn)擊");

b1.addActionListener(this);//為按鈕添加監(jiān)聽(tīng)

c.add(b1, BorderLayout.SOUTH);//添加按鈕到c容器中，并分配在容器南（下）方

jta = new JTextArea();

c.add(jta, BorderLayout.CENTER);//添加文本區(qū)到c容器中，并分配在居中位置

this.setTitle("按鈕事件");//設(shè)置窗口標(biāo)題

this.setSize(300, 300);//設(shè)置窗體大小

this.setVisible(true);//窗體設(shè)置為顯示

// this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//關(guān)閉窗體

//常用的一種關(guān)閉窗體的方法

this.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

System.exit(0);

}

});

}

public void actionPerformed(ActionEvent e) {

//使用判斷按鈕名稱(chēng)的方法觸發(fā)事件

if("點(diǎn)擊".equals(e.getActionCommand())) {

jta.setText("按鈕被點(diǎn)擊了!");

}

//也可以獲取對(duì)象名實(shí)現(xiàn)判斷

// if(e.getSource() == b1) {

// jta.setText("按鈕使用getSource方法被點(diǎn)擊了!");

// }

}

public static void main(String[] args) {

new JFrameTest();

}

}
