How to execute the jar file from a java class

Question

I am having the java main application which needs to execute another jar file and return it without waiting for the jar execution complete. Is it possible to achieve it using Java. Can anyone give some inputs in it.

Do following:

Runtime.getRuntime().exec("java -jar <PATH_OF _JAR>");

in your Main class.

And as @Yoav has suggested. You need to take care of errors by adopting proper error handling strategy.

Yes true. Proper error Handling is required. – Pramod S. Nikam Nov 27 '17 at 10:32
Runtime.getRuntime().exec("java -jar "); return. Will it trigger the jar and return my main function immediately? – Soorya Prakash Nov 27 '17 at 10:33
