1,QT Download Installation:
sudo apt-get install qt4-dev-tools qt4-doc qt4-qtconfig Qt4-designer
Qmake-v, view QT version
2, if the computer does not have the C + + development environment installed, it also requires:
sudo apt-get install build-essential g++ gcc-4.3-doc
3,eclipse for C + + (Eclipse IDE for C + + developers): http://www.eclipse.org/downloads/
File is: eclipse-cpp-helios-sr1-linux-gtk.tar.gz
4,eclipse qt Plugin: http://qt.nokia.com/developer/eclipse-integration

5, download JDK:
Http://java.sun.com
Second, install:
0, install the configuration jdk.
sudo chmod u+x/usr/lib/jvm/java/jdk1.6.0_12.bin
Modify bin file permissions so that it is executable


Then, execute
Sudo-s/usr/lib/jvm/java/jdk1.6.0_12.bin
will appear subtitles, continue to press ENTER, until the screen display requires input yes/no, then enter Y return, will extract the JDK to the folder, get Jdk1.6.0_12 directory.


At this point, the JDK is installed and configured below
Perform

Reference:
Path= "...:/usr/lib/jvm/java/jdk1.6.0_12/bin"
classpath=.:/ Usr/lib/jvm/java/jdk1.6.0_12/lib
Java_home=/usr/lib/jvm/java/jdk1.6.0_12


Perform
sudo source. bashrc
At this point, the environment variables are set successfully (there are many ways to set up environment variables, not listed)


There may be default JDK, such as OpenJDK, in Ubuntu, so in order to use the JDK we have installed by default, the following work is done.
Perform
Update-alternatives--install/usr/bin/java Java/usr/lib/jvm/java/jdk1.6.0_12/bin/java 300
Update-alternatives--install/usr/bin/javac Javac/usr/lib/jvm/java/jdk1.6.0_12/bin/javac 300
This step adds the JDK we have installed to the Java menu.


And then execute
Update-alternatives--config Java
Select the system default JDK through this step


So, then enter in the shell
Java-version
