Installed Java 7 on Mac OS X but Terminal is still using version 6

by

I’ve installed JDK 7u7 downloaded from oracle’s website. But after installation, the terminal is still showing java version 6

$java -version
java version "1.6.0_35"
Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811)
Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode)

any idea why java 7 is not showing up?

Ans:
OK, the problem has been resolved. Here is the answer:
I found that my Terminal has a .bash_profile and the java home variable is set to 1.6

export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home"

So this is the line causing the problem every time I opened a new terminal window.
Simply remove this line will solve the problem. You still need to follow what @aleroot said, but if that doesn’t work for you, check the .bash_profile (or .bashrc) setting file to see if you’ve previously exported any java version.
