Java needs not to be installed by some setup program. Just copy the 
files and you are fine. This applies to Linux and Windows as well.

Only a recent Java should be installed ordinarily, to protect 
applications that use the default Java from security issues.

To switch between the versions it is usually sufficient to invoke the 
Java executable with a full qualified path. Sometimes it may be required 
to set the JAVA_HOME environment variable to the folder where your 
specific version is located. E.g.

SET JAVA_HOME=C:\Java\jre1.4.2
%JAVA_HOME%\bin\java ...

export JAVA_HOME=/opt/java/jre1.4.2
/opt/java/jre1.4.2/bin/java ...

BTDTMT.
