13

Sample Output : 
Positive

Sample Input : 
-13

Sample Output : 
Negative, I have written this Solution Code: import java.io.*;
import java.util.*;



class Main {
	public static void main (String[] args) throws IOException {

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

		String s=br.readLine().toString();
		int n=Integer.parseInt(s);
		int ch=0;
		if(n>0){
			ch=1;
		}
		else if(n<0) ch=-1;

		switch(ch){
			case 1: System.out.println("Positive");break;
			case 0: System.out.println("Zero");break;
			case -1: System.out.println("Negative");break;
		}

	}
}, In this Programming Language: Java, Now tell me if this Code is compilable or not?
