Can we have different method types for the main method and its parameters?

Question

Referring to the following code:

static int sum(int val1, int val2) {
return val1 + val2;
}

Could it be that the sum was a String but the values were int?
I cannot think of an example where it would work but is it possible?

Answer 1

I think it is possible, I'm not super-familiar with java, but some languages have a function called "stringify", or you can have the result go to a variable and type cast it to a string
