Spiral Numbers - Time Limit Exceeded in JAVA

general

I do not understand why this simple code is giving me TLE.
Here is the problem :http://www.codechef.com/problems/SPRLNMS
My solution is this:

import java.io.*;
class Spiral
	{
	public static void main(String[]args)throws IOException
	{
	try
	{
	PrintWriter out=new PrintWriter(System.out);
	BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
	int t=Integer.parseInt(br.readLine());
	
	while(t-->0)
	{
	int n=Integer.parseInt(br.readLine());
	int ans=n*((4*n)-3);
	out.println(ans);
	out.flush();
	}
	}
	catch(Exception e){}
}
}

Why is this giving me TLE ?
How can I make it faster?
