I have
java j2re1.4.12 installed on my desktop. I have installed newer version jre6. How can I check which version is in effect now ?
In previous version , it says j2re while in new version it says jre. Why did 2 disappear ?
If older version is in effect , how can I replace it with new version ?
In the "PATH" variable, path shown is c:\WINDOWS\system32" , where java.exe file is kept. At the same time , there is java.exe file in the path "C:\Program Files\Java\j2re1.4.2_04\bin". When file is in two places, the one in "PATH" variable will be used for executing class files ?
How can I check, what version of java.exe file is in use ? I clicked on the properties of java.exe specifies in "PATH" variable and it shows "6.0.110.3" under version tab, does it mean that version 6 is in use instead of version 4 ? If yes, then how did version 4 got replaced with version 6 ?
java.exe and javac.exe are two different files, right ?
We need javac.exe file for compiling source code. javac.exe file is nowhere in the path "C:\WINDOWS\system32" and I dont see this file anywhere in thye bin folder. So how can javac.exe be used ?
thanks
