Before I installed Java JDK1.6 on WinXP machine I typed from the CMD line
c:\javac
'javac' is not recognized as internal command ...
Here I concluded I did not have a JDK installation on my PC
So, I installed java 1.6.0_30
c:\javac
Usage: javac <options> <source> files . ....
Conclusion: I now have JDK 1.6 installed
c:\java -version
java version "1.4.2_06"
Conclusion: I don't have JDK 1.6
Discovery: I have the following files on my hard disk as follows:
c:\DevSuiteHome\jre\1.4.2.\bin\java.exe -- before I installed JDK 1.6
c:\Program Files\Java\jdk1.6.0_30\java.exe -- recently installed.
My PATH Environment points to both JDKs
c:\path
c:\DevSuiteHome_1\jck\jre\bin;c:\Program Files\Java\jdk1.6.0_30\jre\bin...
Questions: How can I get 'java -version' to reference 1.6.0_30? Can I expect errors with my java code because I have two JDK versions?
