challenge question

Question

What is the output of this code?
interface P {
void print(int x);
}
class Main implements P {
void print(int x) {
System.out.print(x);
}
public static void main(String...arg) {
P ob = new Main();
ob.print(10);
}
}

I didn't understand what is the error

Answer 1

"All abstract, default, and static methods in an interface are implicitly public, so you can omit the public modifier." [in interface]

class Main implements P {
public void print(int x) { //added public

if you implement print without public, you change public method to non public.
it causes error.
