    Default 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.

    You forgot the dot between System and out.
    Also post code inside code tags:
    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;
            it nB = A*B*2;
            int C = B*B; 
            System.out.println("("+nA+"x^2 + " + nB +"x + " + C ); 
        }
    }

    Okay thanks, it works now, and I will. I just got this account today, so I wasn't sure how it was supposed to be done.
