Hi, what is the problem?

Question

can i write this?

static void c(int x , int y) {
system.out.println(x*y)
}

is it wrong at all? or we can edit this

public class Program
{
static void e (int x) {
System.out.println(x);
}
static void h (int y) {
System.out.println(y);
}
public static void main(String[] args) {
int sum = 0;
e(4);
h(3);
sum = e(4) + h(3);
System.out.println(sum);
}
}

Answer 1

//in your class called program,when u call with e(4) and h(3), they'll print as:
4
5
//but when u try to print sum it will print "0" because e(4) and h(3) will return 0 cuz the return type is void

Answer 2

ty and about the question number one?
