1. Install the JDK development environment
Attached to the JDK installation package Baidu Cloud link
Link: http://pan.baidu.com/s/1mh6QTs8 Password: Jkb6 (of course, go to the official website to download the best, you can download to the latest version)
The normal installation of the download process, see the following operation:
Baidu Search: JDK
You will see the following interface:
Download site: http://www.oracle.com/
To start installing the JDK:
Modify the installation directory as follows:
When you are sure, click Next.
Note: When prompted to install the JRE, you can choose not to install.
2. Configure Environment variables:
For Java program Development, the main use of the JDK's two commands: Javac.exe, Java.exe. Path: C:\Java\jdk 1.7.0 _09\bin. However, because these commands are not part of the Windows own commands, you need to configure the path to use them.
Click Computer-Properties-Advanced system settings, click Environment Variables. Click New under the System Variables column to create a new system environment variable.
(1) New variable name "java_home", variable Value "C:\Java\jdk1.8.0_05" (that is, the JDK installation path)
(2) Edit, variable name "Path", at the end of the value of the original variable plus "; %java_home%\bin;%java_home%\jre\bin "
(3) New variable name "CLASSPATH", Variable Value ".; %java_home%\lib;%java_home%\lib\dt.jar;%java_home%\lib\tools.jar "
For example:java_home environment variable operation is as follows:
3, confirm whether the environment configuration is true:
In the console, enter the java,javac,java-version command separately, with the compiler information for the JDK as shown below, including information such as modifying the syntax and parameter options for the command.
Java command:
Javac command:
Java-version command:
4. Verify the first Java program under the console:
Class Test { void Main (string[] args) {Systerm.out.println ("Hello Java");}}
Write in Notepad, click "Save", and deposit the C packing directory, enter javac Test.java and java Test command, you can run the program (print out the result "Hello Java"). Note: These two commands are under the D:\java\jdk1.8.0_20\bin directory.
Program parsing:
First write the Java source Code program, extension. java;
In command-line mode, enter the command: Javac the source file name. Java, compile the source code, generate a class bytecode file;
After compiling, if there is no error message, enter the command: Java HelloWorld, the class bytecode file interpretation run, do not need to add the. class extension. See:
Note: If you enter the Javac test.java command in CMD, the display of ' Javac ' is not an internal or external command because the JDK development environment or environment variable configuration is not installed in the wrong place.

MyEclipse10.0 Registration Hack Step
To provide you with a hack tool, attached to the Baidu Cloud Link:
Link: http://pan.baidu.com/s/1nvfuN3b Password: 64ov
This article takes MyEclipse Professional 10.0 as an example to explain how to crack myeclipse 10.x.
The cracked patches used in this article are valid for the 10.x version of MyEclipse standard/professional/blue/spring (for example: MyEclipse 10.0, MyEclipse 10.1, MyEclipse 10.5, MyEclipse 10.6, MyEclipse 10.7.1, etc.).
Operating Environment Description:
Operating system: Windows 7 SP1 Ultimate 64-bit
Myeclipse:myeclipse Professional 10.0
1, Run crack patch
This is the list of files extracted after the decompression of the patched files. As shown in, the main file Cracker.jar is used to run and crack myeclipse. For cross-platform compatibility, the cracker is developed in Java, so we need to make sure that the Java Runtime environment is installed correctly on the computer.
Enter the system command interface type command: java -jar cracker.jar
(if it is a Windows operating system, you can also directly double-click to run the run.bat batch file), we can see the graphical interface of the cracked program.
2. Generate Registration code related information
As shown, we first enter Usercode (which can be entered arbitrarily), then select the currently installed MyEclipse version, then click "SystemID" and "Active" in turn.
3. Regenerate the key file
As shown, when we click "Active" in the previous step, the cracker generates license key, Activation Code, Activation key, and so on.
Next, we click "Tools", "Rebuildkey" in the menu bar to regenerate the key file.
4. Replace the MyEclipse related jar file
Next, we click on the menu bar "Tools", "Replacejarfile".
Make sure that the MyEclipse is not running at this time, or the substitution cannot succeed.
In the pop-up Directory selection dialog box, select the MyEclipse plug-in directory, and then click Open.
In the 10.x and previous versions of MyEclipse, the plugin directory was: MyEclipse安装目录\Common\plugins
.
In the 2013 and later versions of MyEclipse, the plug-in directory is: MyEclipse安装目录\plugins
.
5. Save MyEclipse User Profile
Finally, click "Tools", "saveproperties" on the menu bar.
We opened MyEclipse 10 this software found that no popup that prompt box, if you want to see if the activation has not been successful, click on the menu bar MyEclipse under the subscription information, if you see the following display instructions is the activation success!
summarize the above myeclipse 10.0 crack cracking steps:
"First Step": Enter any user name
"Second Step": Click SystemID ... button to automatically systemid the cost of the machine.
"Step three": Point menu Tools->rebuildkey
"Fourth Step": Click the active button. Will be generated in the display area
License_key
Activation_code
Activation_key
Do not open MyEclipse activation page input at this time.
"Fifth Step": Open menu Tools->replacejarfile, pop-up File selection dialog box, locate
Select Plugins folder (myeclipse\common\plugins\) under the MyEclipse installation directory Common folder
Click Open, the program will get stuck, don't worry, the file is being replaced!
After a while, the message will be output, the file has been replaced
"Sixth Step": Point menu Tools->saveproperites
Ok. Open your myeclipse no longer need to enter the activation code or something.
=========== "Manual replacement of public key and integrity check file method steps" ===============
To manually replace the public key and integrity check file method steps: (If you do not replace the public key and the integrity check file, the computed sequence number is invalid)
"1". Replace directory D:\Program Files\myeclipse\common\plugins\com.genuitec.eclipse.core.common_10.0.0.me201110301321.jar
\com\genuitec\eclipse\core\
Under "Signatureverifier.class" (Integrity check file)
"2". Replace directory D:\Program Files\myeclipse\common\plugins\com.genuitec.eclipse.core_10.0.0.me201110311918.jar
\com\genuitec\eclipse\core\
Next Publickey.bytes file
============
Rebuildkey: Manually generate your own new keys and public keys, tools-and Rebuildkey, to the current directory and overwrite the original files if they exist. Do not forget to replace the jar file with MyEclipse (file "2") after the build.
#破解程序可以计算序列号和激活码.
1. SystemID can be seen in the MyEclipse activation window
2. Click SystemID ... button to automatically systemid the cost of the machine.
3. Click the active button to calculate the serial number and activation code. The computed information is displayed in the text box below.
======= If the registration is successful, the following will not be seen ======================
#点击Systemid ... button to automatically systemid the cost of the machine.
One line error may occur cannot find Jniwrapper native library (libjniwrap.so) in java.library.path:~~
No need to pay attention, click again to appear systemid.
#破解不成功主要原因有两个
(1) Produced by the SystemID and EXE cracked out of the corresponding, this problem I also studied, no problem, because myeclipse inside as long as found to the previous group of data, SystemID even on the.
If an operating system systemid, open myeclipse---myeclipse----Subscription infomation--Enter the user name Activation code----Activate now---web active---- You'll see the URL with the parameters Sytemid
(2) Publickey.bytes does not replace, please replace, the program has this function (Tools->replacejarfile, see the above description).
To be skilled, to be warm, the more efforts to be lucky, not to let those who have paid for my disappointment-----angel_kitty
