  2. 我set兩個path的方法：
    1.開始，搜尋，所有檔案和資料夾，search “javac”
    　搵到之後，right click個檔案，內容，copy佢個位置；
    　再按開始，執行，打”cmd”，出左個Dos(黑畫面)，打”path 「你果個位
    　置」”，咁就應該可以set到javac既path了。
    2.Set compile file path,即係將java轉class的過程。當你寫完個
    　java，save左檔案，right click個檔案，內容，copy佢個位置；
    　再按開始，執行，打”cmd”，出左個Dos(黑畫面)，打”cd 「你果個位
    　置」”，再打”javac 你個file name”，such as”pong.java”；咁就應該
    　可以set到compile file path，而且可以complie java file to
    　class file.

  3. import java.util.Scanner; //Use class “Scanner”

    public class test
    {
    public static void main(String args[])
    {

    Scanner input = new Scanner(System.in);

    int base;
    int height;
    int sum;

    System.out.print(”Base=”);
    base = input.nextInt(); //enter the base

    System.out.print(”Height=”);
    height = input.nextInt(); //enter the height

    sum = base + height; //cuclate what the sum is

    System.out.printf(”Sum=”,sum); //display the sum
    } //end method main

    } //end class test

    //the sum cannot show out

  4. 呀sir, 我整完個path都係咁既死樣(唔得~~)。係cmd到打”javac” 佢係度話呢個唔係指令!!!
    我果個path原本係”%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Adobe\AGL”
    之後我咪係最尾個度加左java果段野:
    “%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Adobe\AGL;C:\Program Files\Java\jre1.6.0_2″
    但係都係唔得，我真係唔明點解

  5. //Sir, 唔知呢段有冇啲野可以參考ａｒ？
    import java.io.*;
    import java.net.*;

    public class EchoClient {
    public static void main(String[] args) throws IOException {

    Socket echoSocket = null;
    PrintWriter out = null;
    BufferedReader in = null;

    try {
    echoSocket = new Socket(”taranis”, 7);
    out = new PrintWriter(echoSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(
    echoSocket.getInputStream()));
    } catch (UnknownHostException e) {
    System.err.println(”Don’t know about host: taranis.”);
    System.exit(1);
    } catch (IOException e) {
    System.err.println(”Couldn’t get I/O for ”
    + “the connection to: taranis.”);
    System.exit(1);
    }

    BufferedReader stdIn = new BufferedReader(
    new InputStreamReader(System.in));
    String userInput;

    while ((userInput = stdIn.readLine()) != null) {
    out.println(userInput);
    System.out.println(”echo: ” + in.readLine());
    }

    out.close();
    in.close();
    stdIn.close();
    echoSocket.close();
    }
    }

  6. jre裡面係冇javc程式既,要響jdk裡面先有
    “%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Adobe\AGL;C:\Program Files\Java\jre1.6.0_2″
    所以首先你要搵番jdk file,然後link番落去,咁先可以行到javac.
