So in java, we use scanner because using this, we dont have to initialize in program, we can take inputs. Is that correct?

Yes the Scanner class is used to take user input and the variable which is going to hold a value assigned by the Scanner need not be initialized before hand.
Because there is no point doing that.

You are taking both inputs in num1.
Change the 2nd one to num2.

Your code is not working because you declare num1 twice. Line 9 should be: int num2 =...
Also when printing the result, you are actually multiplying. To add the numbers put them in parentheses, otherwise they are just concatenated to the text: (num1 + num2)

Ira Sarkar kindly change that num1 * num2 to num1+num2 and observe the result just like Tibor Santa mentioned.
