link－list java版

最近在学习数据结构的Java表示方法（本来C描述的就学不好，但觉得到时做毕业论文可能有用，所以就再学）

这是一个link－list的例子，半图形界面，但还没有调试成功。

Main.java是运行主类，ListTest.java是图形界面，List.java是链表主代码

Main.java

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class Main

{

public static void main(String [] args)

{

ListTest listTest = new ListTest();

listTest.init ();

listTest.setSize (400,400);

listTest.setVisible (true);

}

}

ListTest.java

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

import java.lang.*;

public class ListTest extends JFrame

{

private JButton addAtF,addAtB,delFrF,delFrB,print;

private JTextField input;

private JLabel display;

private JPanel p1,p2,p3,p4;

private Container container;

private List myList;

Listener listener;

public void init()

{

Listener listener = new Listener();

List myList = new List();

JTextField input = new JTextField(35);

JLabel display = new JLabel("Result: ");

JButton addAtF = new JButton("addAtF");

JButton addAtB = new JButton("addAtB");

JButton delFrF = new JButton("delFrF");

JButton delFrB = new JButton("delFrB");

JButton print = new JButton("print");

JPanel p1 = new JPanel();

JPanel p2 = new JPanel();

JPanel p3 = new JPanel();

JPanel p4 = new JPanel();

container = getContentPane();

p1.add (input);

p2.add (display);

p3.add (addAtF);

p3.add (addAtB);

p3.add (delFrF);

p3.add (delFrB);

p3.add (print);

p4.add (p1);

p4.add (p2);

p4.add (p3);

container.add (p4);

addAtF.addActionListener(listener);

addAtB.addActionListener(listener);

delFrF.addActionListener(listener);

delFrB.addActionListener(listener);

print.addActionListener(listener);

}

class Listener implements ActionListener

{

public void actionPerformed( ActionEvent e)

{

double ran = 100 * Math.random();

int ranInt = (int)ran;

Integer objInt = new Integer(ranInt);
