    Default Small help with my code :) (SOS)

    So, I have homework until tomorrow, I've been sitting trying to find my problem for an hour and I couldn't find. No, it doesn't give me an error, but the compilator doesn't progress after a user enters a number.
    The assignment is to write a program which detects if a number is a positive one, a negative one or a zero. (We must use nested if statement)

    	package gg;
    import java.util.*;
    public class AAA {
    	public static void main(String[] args) {
    int a;
    Scanner kb = new Scanner (System.in);
         System.out.print("Please enter any number: ");
     a=kb.nextInt();
     
     if (a==0){
        	System.out.print("The number is a zero");
        if(a>0) {
        	System.out.print("The number is positive.");
        }
        else {
        	System.out.print("The number is negative.");
        }
      }
     
        kb.close();
    	}
     
    }
    I feel so stupid lol, I need a more difficult program in class, yet cannot do this simple one.

    Check that the enclosing {}s are correctly placed.

    Also fix the indentations of the code.

    If you don't understand my answer, don't ignore it, ask a question.

    I did check them, everything is correct there. I am trying to write a new code though, hopefully it'll work lol.

    It looks to me like the test for a > 0 is only executed if a == 0. Logically that can never be true.
    There is a misplaced }
