本文详细介绍了如何在Ubuntu系统中下载并安装Java。包括选择正确的Linux安装包、使用命令行进行安装、设置环境变量以及配置Java为系统默认版本。

Download the installation package @ http://java.sun.com , we choose the Linux package (not RPM though) to download.

Copy and execute the downloaded .bin file

sudo cp jdk-6u6-linux-i586.bin /opt      # We are going to install the package under /opt
cd /opt
sudo ./jdk-6u6-linux-i586.bin

# Click space button to read through the license agreement, and input "yes" when being prompted.

Make a symbolic link to make the life easier in the future

sudo ln -s ./jdk1.6.0_06/ ./jdk1.6

# From now on, you can point the JAVA_HOME to /opt/jdk1.6

Put Java into system alternatives:

sudo alternatives --install /usr/bin/java java /opt/jdk1.6/bin/java 1
sudo alternatives --config java

# You would see the following screen:
There is 1 program that provides 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           /opt/jdk1.6/bin/java

Enter to keep the current selection[+], or type selection number:

# We don't have other options, so just select 1.

注意的一点是在ubuntu中alternatives用update-alternatives替换。
