Thread: What's wrong with this program?

I keep getting this error:
"
Main.java:8: error: ';' expected
System out.println("input A:");
^
1 error
"

Here's the program:

import java.io.*;
import java.util.Scanner;
class Main {
  public static void main (String[] args) throws Exception {
System.out.println("hello world");
    Scanner asd = new Scanner(System.in);
    System.out.println("(Ax + B)^2");
    System out.println("input A:");
    int A = asd.nextInt(); 
    System.out.println("input B:");
    int B = asd.nextInt();
    int nA = A*A;
    int nB = A*B*2;
    int C = B*B; 
    System.out.println("("+nA+"x^2 + " + nB +"x + " + C ); 
 
  }
}

I've already checked for the lack of semicolons, so does anyone know what might be causing it? Any help would be appreciated, I'm using an iPhone app instead of what I ordinarily use, which is netbeans.
