Some games online require Java to play, however it says that I have a missing plug-in. I am worried that I might get the java-exploit if I downloaded Java, any advice ?

I found Java 1.7 SDK in /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk, and all the binaries in /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home/bin.
And by clicking the jdk file, I could arrange the order so that Java SE 7 is executed first.
java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)
And I could also bring up the app from /Applications/Utilities/Java Preferences.app
For eclipse, I could add one line in /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini to teach eclipse what Java it will use :
-vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
The problem is that you have two Java Runtime Environments (JREs) installed on your system, Apple's 1.6.x and Oracle's 1.7.x. As evidenced by running java -version JRE 1.6 is the default JRE on your system. You likely want to change the default JRE to Oracle's 1.7 JRE.
You are correct in that there used to be a System Preference for setting the default JRE. Apple removed that as part of the Java Mac OS X 2012-006 update. The new way for selecting the default JRE is to use the /usr/libexec/java_home command. Read the java_home man page as well as the Determining the Default Version of the JDK section of this Oracle page for more info on how to specify the default JRE.

Apple is automatically disabling old versions of Java for security reasons. If you re-install Java you do certainly run a slight risk of exposing your computer to known "in-the-wild" exploits. This is a decision you are best suited to make. Are the games worth installing Java for? Are there alternate places to play the same games without using Java?
