Java Training Course/JT04

• Create a file DupInt.java by copying the program DupString.java from JT03, rename the class and replace 3 lines:

       int st0 = Integer.parseInt(args[0]); // the 1st parameter on the commandline
       int st1 = Integer.parseInt(args[1]); // the 2nd ...
       int st2 = st0 + st1;

• Compile
• Predict the output of:

java DupInt 2 4
java DupInt 2 -4
java DupInt 0 -1

• Bonus question: What will happen if you run the program without any parameter?
