As the subject said, i need a dos script to check the version of java installed on windows xp Machine.
Furthermore, I need to check if the version is greater than a prefixed value 1.x.

Anyone can help me?

Answer 1

Getting the version, and write it into a temp file. Then only parse the version itself:

@echo off
echo off
java -version 2> tmp_java_version.txt
set /p JAVA_VERSION= < tmp_java_version.txt
del tmp_java_version.txt
set JAVA_VERSION=%JAVA_VERSION:~14,3%

echo %JAVA_VERSION%
pause > NUL
