First ever java code

[laserpp]

Alright first off I think my JCreator isn't working right because I got it off of my school website for free. When I try to run the program I get a message about setting about a JDK path or something and that I need the newest version. I can right code in it but don't know if it will allow me to run it. Well back to the code.


What I got to do it create a program that reads from a file of baseball scores, name, at bats(ab) and hits. Then get the avg by ab/hits and output it to a file that the user names. The output file should be: Name Ab Hits Avg. Here's the code.

/**
 * @(#)baseball.java
 *
 * baseball application
 *
 * @author 
 * @version 1.00 2011/2/5
 */
 
import java.util.Scanner;
import java.io.*;
	
class baseball {
	
	public static void main(String[] args) {
    	
	String file = "C:\\Users\\Welcome Back\\Desktop";
	input Scanner = new Scanner(new FileReader(file));
	
	System.out.println("Enter the file to write to: ");
	File outFile = new File(in.next());
	
	String name;
	int ab;
	int hits;
	float avg;
	name = input Scanner.nextLine();
	ab = input Scanner.nextLine();
	hits = input Scanner.nextline();
	
	avg = hits/ab;
	
	System.out.printf(avg);
	
	}
	
	
}

ERROR:
';' expected for lines 27,28,29....

FINALLY got it all working, I am way sure that I made this like 100 times more complicated then what the professor wanted, and I really don't understand what half it is doing, going to ask the professor on my free time to go through line by line so I can learn it better.


DRUM ROLL PLEASE


BOOM =DDDDDDDDD
