Definitely, you will get different outputs. The output depends on your input values. After compiling the code, if you run the code with the following inputs:

java Demo 2 3, it will give output 0 , the try block of method is called which divides one value from other 2/3 whose result is actually a decimal value which is converted to int and gives 0.

java Demo 2 2, it will give output 1 , the try block of method is called which divides one value from other 2/2 and gives 0.

java Demo 3 2, it will give output 0 , the try block of method is called which divides one value from other 3/2 whose result is actually a decimal value which is converted to int and gives 1.

java Demo 2 0, it will give exception, the try block of method is called which passes the condition to catch block as an exception (cannot divided by 0) occurs and display the error 'Div by zero error!'.

If you will not input any number, 
java Demo, it will return ArrayIndexOutOfException: 0.

If you will input only one number,
java Demo 2 it will return ArrayIndexOutOfException: 1.

Finally always execute in any case.
