谁能给我出一道JAVA编程基础的测试题？有没有双重答案的？把答案也给我写上，再给一道C语言的题和答案，谢谢了

x你好 我来回答你的问题

JAVE编程题我这边暂时没有 但是网上应该有很多 关于C语言的编程题 我给你一道十分基础的题目

以下为手打

输入一个带符号的短整形数 输入该数的位数

程序清单如下：

voin main()

{ int x m；

scanf（"%d",&x）；

if （x<0）x=-x

if (x<10) m=1

else if (x<100) m=2

else if (x<1000) m=3

else if (x<10000) m=4

else m=5;

printf("m=%d\n",m);

}

这个是很基础的题目 上面的空格因为为了显示更容易理解所以这样 真正在编程时 空格请自己掌握

因为正在学C 不了解JAVE 则不评论
希望能解决你的问题哦 要是不满意 希望追问哦 O(∩_∩)O~

Java基础？？恩；先吧尚学堂的那个坦克大战；和聊天做出来。。那么你的JavaSe基础就差不多了应该。

下面是哪个聊天：

　　服务器端：

import java.io.*; import java.net.*; import java.util.*;

public class ChatServer { boolean started = false; ServerSocket ss = null; List<Client> clients = new ArrayList<Client>(); public static void main(String[] args) { new ChatServer().start(); } public void start() { try { ss = new ServerSocket(8888); started = true; } catch (BindException e) { System.out.println("端口使用中...."); System.out.println("请关掉相关程序并重新运行服务器！"); System.exit(0); } catch (IOException e) { e.printStackTrace(); } try { while(started) { Socket s = ss.accept(); Client c = new Client(s); System.out.println("a client connected!"); new Thread(c).start(); clients.add(c); //dis.close(); } } catch (IOException e) { e.printStackTrace(); } finally { try { ss.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } class Client implements Runnable { private Socket s; private DataInputStream dis = null; private DataOutputStream dos = null; private boolean bConnected = false; public Client(Socket s) { this.s = s; try { dis = new DataInputStream(s.getInputStream()); dos = new DataOutputStream(s.getOutputStream()); bConnected = true; } catch (IOException e) { e.printStackTrace(); } } public void send(String str) { try { dos.writeUTF(str); } catch (IOException e) { clients.remove(this); System.out.println("对方退出！"); //e.printStackTrace(); } } public void run() { try { while(bConnected) { String str = dis.readUTF(); System.out.println(str); for(int i=0; i<clients.size(); i++) { Client c = clients.get(i); c.send(str); //System.out.println(" a string send !"); } } } catch (EOFException e) { System.out.println("Client closed!"); } catch (IOException e) { e.printStackTrace(); } finally { try { if(dis != null) dis.close(); if(dos != null) dos.close(); if(s != null) { s.close(); //s = null; } } catch (IOException e1) { e1.printStackTrace(); } } } } }

　　客户端：

　　import java.awt.*; import java.awt.event.*; import java.io.*; import java.net.*;

public class ChatClient extends Frame { Socket s = null; DataOutputStream dos = null; DataInputStream dis = null; private boolean bConnected = false;

TextField tfTxt = new TextField();

TextArea taContent = new TextArea(); Thread tRecv = new Thread(new RecvThread());

public static void main(String[] args) { new ChatClient().launchFrame(); }

public void launchFrame() { setLocation(400, 300); this.setSize(300, 300); add(tfTxt, BorderLayout.SOUTH); add(taContent, BorderLayout.NORTH); pack(); this.addWindowListener(new WindowAdapter() {

@Override public void windowClosing(WindowEvent arg0) { disconnect(); System.exit(0); } }); tfTxt.addActionListener(new TFListener()); setVisible(true); connect(); tRecv.start(); } public void connect() { try { s = new Socket("127.0.0.1", 8888); dos = new DataOutputStream(s.getOutputStream()); dis = new DataInputStream(s.getInputStream()); System.out.println("connected!"); bConnected = true; } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } public void disconnect() { try { dos.close(); dis.close(); s.close(); } catch (IOException e) { e.printStackTrace(); } } private class TFListener implements ActionListener {

public void actionPerformed(ActionEvent e) { String str = tfTxt.getText().trim(); //taContent.setText(str); tfTxt.setText(""); try { //System.out.println(s); dos.writeUTF(str); dos.flush(); //dos.close(); } catch (IOException e1) { e1.printStackTrace(); } } } private class RecvThread implements Runnable {

public void run() { try { while(bConnected) { String str = dis.readUTF(); //System.out.println(str); taContent.setText(taContent.getText() + str + '\n'); } } catch (SocketException e) { System.out.println("退出了，bye!"); } catch (EOFException e) { System.out.println("退出，bye - bye!"); } catch (IOException e) { e.printStackTrace(); } } } }
