实训报告详细内容包括：
一． 实训每日报告
1.13：
一.通过这节课我学到了
1.通过继承线程类Thread编写线程。
2.通过实现Runnable接口来创建线程。
3.使用静态方法sleep()让线程沉睡若干秒。
4.使用while和if语句改变球的运动轨迹，实现反弹。
二．
import java.awt.*;
public class MyBall{
public static void main(String args[]){
Frame w= new Frame();
w.setSize(300, 400);
MyPanel2 mp = new MyPanel2();
w.add(mp);
Thread t = new Thread(mp);
t.start();
w.show();
}
}
class MyPanel2 extends Panel implements Runnable{
int x = 30;
int y = 30;
int f =0; //f== 0;f ==1;f == 2;f ==3；
public void paint(Graphics g){
g.fillOval(x,y,20,20);
}
public void run(){
while(true){
//定义飞行状态
if(f==0){
x++;
y++;
}
if(f==1){
x--;
y++;
}
if(f==2){

三.每一节课都有不同的收获，通过这节课的学习使自己对编程的感兴趣更加深了一步，希望通过以后的努力，可以取得更大的进步。
1.16：
一.通过这节课我学到了在用Swing编写程序时利用JFrame创建窗体，并用布局管理器的方法实现qq登录。
二.
package qqdenglu;
import java.awt.*;
import javax.swing.*;
public class QQLogin {
public static void main(String args[]){

w.add(panInput,BorderLayout.CENTER);
w.add(panButton,BorderLayout.SOUTH);
w.show();
}
}
三.心得：通过这节课，使我真正感到java编程的神奇之处，明白了java实践的重要性，加深了我对编程的乐趣，使我更有信心学好这门课。
1.17：
一，学习了注册事件，设置账号密码，引用成员变量，使用this关键字。
二，
登陆
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class QQLogin1 extends JFrame implements ActionListener {
JTextField textUser = new JTextField();
JPasswordField textPass = new JPasswordField();
public QQLogin1(){
//设置窗体属性
this.setSize(250, 125);
this.setLocation(400, 300);
this.setTitle("QQ登陆");
//一大堆组件
JLabel labUser = new JLabel("用户名");
JLabel labPass = new JLabel("密码");
JButton btnLogin = new JButton("登录");
JButton btnReg = new JButton("注销");
JButton btnCancel = new JButton("取消");
//注册事件
btnLogin.addActionListener(this);
btnReg.addActionListener(this);
btnCancel.addActionListener(this);
//布置输入面板
JPanel panInput = new JPanel();
panInput.setLayout(new GridLayout(2,2));
panInput.add(labUser);
panInput.add(textUser);
panInput.add(labPass);
panInput.add(textPass);
//布置按钮面板
JPanel panButton = new JPanel();
panButton.setLayout(new FlowLayout());
panButton.add(btnLogin);
panButton.add(btnReg);
panButton.add(btnCancel);
//布置窗体
this.setLayout(new BorderLayout());
this.add(panInput,BorderLayout.CENTER);
this.add(panButton,BorderLayout.SOUTH);
}
public static void main(String[] args) {
QQLoggin1 w = new QQLoggin1();
w.setVisible(true);
}
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equals("登录")){
String user = textUser.getText();
String pass = textPass.getText();
if(user.equals("aaa")&&pass.equals("111")){
QQmain w = new QQmain();
w.setVisible(true);
this.setVisible(false);
System.out.println("欢迎");
}else{
System.out.println("输入有误，请重新输入");
}
}
if(e.getActionCommand().equals("注册")){
}
if(e.getActionCommand().equals("取消")){
}
}
}
三，通过一遍又一遍的练习，加深了对程序的了解和记忆能力，更加喜欢上编程，写程序是一件看似枯燥实则有趣的事情。
1.18：
一.通过这节课，使我了解到常用I/O流的使用。实现了文件加密,文件解密和恢复文件。
二，
文件加密：
import java.io.*;
import javax.imageio.stream.FileImageInputStream;
public class ReadFile {
public static void main(String args[]){
try{
//读密钥文件
File keyFile = new File("d:/test/key.key");
FileInputStream keyFis = new FileInputStream(keyFile);
int [] key = new int[128];
for (int i = 0 ; i < 128 ; i++){
key[i] = keyFis.read();
}
//加密
File inFile = new File("d:/test/aaa.txt");
File outFile = new File("d:/test/bbb.txt");
FileInputStream fis = new FileInputStream(inFile);
FileOutputStream fos = new FileOutputStream(outFile);
int size= fis.available();
for(int i = 0 ; i < size ; i++){
fos.write(fis.read()+key[i%128]);
}
}catch(Exception e){}
}
}
文件解密：
import java.io.*;
public class ReadFile1 {
public static void main(String args[]){
try{
//读密钥文件
File keyFile = new File("d:/test/bbb.txt");
FileInputStream keyFis = new FileInputStream(keyFile);
int[] key = new int[128];
for( int i = 0 ; i < 128 ; i ++ ){
key[i] = keyFis.read();
}
//解密
File f = new File("d:/test/bbb.txt");
FileInputStream fis = new FileInputStream(f);
int size = fis.available();
for(int i = 0 ; i < size ; i ++){
System.out.println((char)(fis.read()-key[i%128]));
}
}catch(Exception e){
e.printStackTrace();
}
}
}
恢复文件：
import java.io.*;
public class ReadTxtFile {
public static void main(String args[]){
try{
File inFile = new File("d:/test/aaa.txt");
File outFile = new File("d:/test/bbb.txt");
FileReader fr = new FileReader(inFile);
BufferedReader br = new BufferedReader(fr);
FileWriter fw = new FileWriter(outFile);
PrintWriter pw = new PrintWriter(fw);
while(br.ready()){
pw.println(br.readLine());
}
pw.close();
}catch(Exception e){}
}
}
三，虽然打字速度比较慢，但是通过一遍又一遍的练习，加深了对程序的了解和记忆能力，更加喜欢上编程，写程序是一件看似枯燥实则有趣的事情。

PrintWriter pw=new PrintWriter(osw,true);
pw.println("GET / HTTP/1.1");
pw.println("Accept: text/html, application/xhtml+xml, */*");
pw.println("Accept-Language: zh-CN");
pw.println("User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0");
pw.println("UA-CPU: AMD64");
pw.println("Accept-Encoding: gzip, deflate");
pw.println("Host: 127.0.0.1");
pw.println("Connection: Keep-Alive");
pw.println("");
InputStream is=s.getInputStream();
InputStreamReader isr=new InputStreamReader(is);
BufferedReader br=new BufferedReader(isr);
System.out.println(br.readLine());
System.out.println(br.readLine());
System.out.println(br.readLine());

二． 实训心得体会
14天的实训在充实与忙碌中度过了，上大学以来这14天让我很难忘。第一节课，本对这次实训不抱太大期望的我被王洋老师的幽默风趣让我改变了看法。简单易懂，由浅入深，思路紧密的授课方式也让认识到以前学习java的方法有问题。以前的我总是只知道看书，看其中的程序，但很少自己动手去打程序。当我自己敲了程序后才发现只有去实践才能找到自己的错误和不懂的地方。王洋老师说的很对，一个程序敲多了自然会明白程序的意思与思路。我还懂得了编程思路的重要性，必须要有严谨的态度。还有细节决定成败。
14天的实训，真的感谢学院为我们做的一切，感谢王洋老师的教学，他是一位伟大的老师，用人格魅力感染了我们，让我们对学习java有了动力。还有其他几位陪在我们身边的老师们，在我们有疑惑时他们会及时出现在我们面前提供帮助。感谢这一切，让我的大学变得与众不同，我也会努力，丰富自己的知识。
