1、
sudo apt-get install flex bison gperf build-essential curl zlib1g-dev g++-multilib g++-4.4-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline-gplv2-dev lib32z1-dev wine mingw32 tofrodos libgl1-mesa-dev

jdk-6u43-linux-x64.bin

注意，必须是1.6版本的，要不会报错

sudo mkdir /etc/java

sudo cp jdk-6u43-linux-x64.bin /etc/java/

cd /etc/java/

sudo ./jdk-6u43-linux-x64.bin

3、配置环境变量 

    $ sudo gedit /etc/profile

在文件的末尾加上如下内容：

# for java

export JAVA_HOME=/etc/java/jdk1.6.0_43

export JRE_HOME=${JAVA_HOME}/jre

export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:$PATH

4. 使设置成效：$ source /etc/profile

查看 ：$ java -version
