Answer 1

Runtime.exec(...) returns Process object which consists following methods

• destroy()
• exitValue()
• getErrorStream()
• getInputStream()
• getOutputStream()
• waitFor()

you can call destroy() which kills the subprocess. The subprocess represented by this Process object is forcibly terminated. or you can kill by passing taskkill /PID <process id> in Runtime.exec(...) or kill -9 <process id>
