This article is about how to install JDK manually on Ubuntu. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Manually install jdk6

First of all, download jdk-6u12-linux-i586.bin from http://java.sun.com, which is said to be easy to operate and does not require conversion.

Then, you can put it in any folder you like, and if it's a rookie like me, it's recommended to put it under the main folder (/ home/*).

Here's how to install jdk:

Enter you to store jdk-6u12-linux-i586.bin under the terminal, for example, my location is: / home/liangshihong

$sudo-s. / jdk-6u12-linux-i586.bin

Enter all the way until you are asked if you want to install it. Enter yes.

Ok, after installation, configure the environment variables below

Configure classpath to modify environment variables for all users

$sudo gedit / etc/profile

Add in the file *

# set java environment

JAVA_HOME=/home/liangshihong/jdk1.6.0_12

Export JRE_HOME=/home/liangshihong/jdk1.6.0_12/jre

Export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

Export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

Restart the computer and test the version of jdk with the command

Java-version

The following message is displayed: successful installation

Java version "1.6.012"

Java (TM) SE Runtime Environment (build 1.6.0_12-b04)

Java HotSpot (TM) Server VM (build 11.2-b01, mixed mode)
