Machine environment: Operating system: WindowsXP SP1, Windows 2000 Sever SP4 The following procedure is a JDK download installation:
1. Click the following URL to enter the JDK1.4 download page:
http://java.sun.com/j2se/1.4.2/download.html
2. Click on "Download J2se SDK":
3. "Accept", Continue:
4. The JDK version under each platform is listed below, where Windows has two installation methods, one is fully downloaded and then installed, one is online installation, we choose the first:
5. After the download is complete, double-click the icon to install, you can customize the installation directory during the installation process.

8. In "System Variable", set 3 properties, Java_Home, Path, ClassPath (
It doesn't matter if you already exist, click "Edit", there is no existence, click "New":
9.java_home Indicates the JDK installation path, which is the path selected when installing.
D: /jdk1.4, this path includes lib, bin, jre and other folders (
This variable is best set, because it is necessary to rely on this variable after running Tomcat, Eclipse, etc.
PATH makes the system to identify the java command in any path, set to:
% Java_home% / bin;% java_home% / jre / bin classpath is the Java Load Class (Class or LIB) path, only classes in classpath, Java commands can be identified, setting to:
.;
% Java_home% / lib;% java_home% / lib / Tools.jar (To add. Representing the current path)
% Java_home% is to reference the Java_home of the previously specified.
10. "Start" -> "Run", type "cmd":
11. Type the command "java -version", appear the following picture, indicating that the environment variable configuration is successful:
12. Ok, finished the collection. Let's start your first Java program, see follow-up article.

Why is it still 1.4, the times are 5.0!

I have to know that some programs can't run in JDK1.5. Now the mainstream application is still 1.4

J2se 5.0 is JDK1.4.2
# 帮 帮 一, 2005-02-15 1:08 PM JHT793
I downloaded the JDK1.4.2_07 version. I set the following java_home = c: /j2sdk1.4.2_07 path = path "% java_home% / bin;% java_home% / jre / bin" classpath =.;% Java_home% / lib ;% Java_home% / lib / Tools.jar, I always prompts if the package system does not exist is not right when I execute the "javac aa.java" command. The program aa.java content is: Class Displayer { Public static void main () {system.out.println ("You'll Love Java!");}}

To jht793: First: J2se 5.0 is not JDK1.4.2 Second: The program name is wrong, Displayer.java

I would like to ask, I use Win2000, use JDK1.4.2, I am the same as you, I entered Java-Version, I am not inside or external command. . . After I entered Javaac, I also said that I have seen many times, it's the same, I don't know where it is wrong, I hope the masters can help me!

To Kelvin: It is definitely that PATH is not set, the system can't find the java command

I downloaded JDK1.4.1_01, system variable I set up java_home = c: /jdk1.4 path = c: /jdk1.4/bin; c: /jdk1.4/jre/bin classpath = .; C: / JDK1.4 / lib; c: /jdk1.4/lib/tools.jar; can I execute the "javac test.java" command always prompts package system does not exist whether my library is not loaded? Test.java content is: public class test {public static void main (string args) {try {system.out.println ("HelloWorld!"); System.out.Println ("Press any key to contact .."); System.in.read ();} catch (exception e) {}}}
