java - How to invoke a long-time task without block the existing batch script? -

i have long-time task implemented in windows batch script need add existing windows batch script, requirement existing script should run before, without being slowed down added task.

i thinking calling task script in java thread might works, there difficulties:

1. how call windows batch script in java thread?

2. how quit java program without stop thread?

maybe wrong start, 1 give me ideas?

i think adding java code complicate task. can run additional batch file in separate process using start command, , might serve purpose:

in first.bat:

@echo calling second.bat start second.bat @echo called second.bat 

this create second command window. if don't want window show up, can use /b parameter, in start /b second.bat
