For what purpose we are using return statement?? Help me to understand clearly and easily

Answer 1

forexample you want a multiple method.
public int multipl(int i, int y){
int M = x * y;
return M;
}
this is really simple i think.

Answer 2

Return returns something.

Void returns nothing.

int test(int x, int y)
{
return x + y;
}

Answer 3

so you can use it like:
class Dog{
var Age = multipl(2,3)
}

Output: Age = 6
