Why is 3 the output of this code?Is it becoz return type of func is void??

Question

public static void func(int x){
x=8;
}

public static void main(String[] args){
int x=3;
func(x);
system.out.println(x);
}

Answer 1

Yes, as function is not returning any value, updated value of x is not visible outside the function func().
So, the value of x remains 3.

Answer 2

Thank u:)
