How to keep cmd from exiting using Java 'Runtime.getRuntime().exec' command

I'm trying to compile and execute a .java file, using a java program.

Runtime.getRuntime().exec("cmd.exe /c start javac myProg.java");
Runtime.getRuntime().exec("cmd.exe /c start java myProg");

The file compiles and i think it runs as well but then it exits. I need to keep the cmd window open.

I tried using \k instead of \c and using pause. They don't seem to work. What am i doing wrong? Thanks in advance :D

Make these changes in your code and it will work. You need to add option /k as shown below.

Runtime.getRuntime().exec("cmd /c start cmd /k javac myProg.java"); 
Runtime.getRuntime().exec("cmd /c start cmd /k java myProg");
