error with basic java code

This is some basic java code:

package javaapplication32;

import java.io.*;

public class JavaApplication32 {
public static void main(String[] args)throws Exception {
try{
out = new DataOutputStream(new BufferedOutputStream(new FileOutputStream("dec.dat")));
in = new DataInputStream(new BufferedInputStream(new FileInputStream("enc.dat")));

String enc=in.readUTF();
System.out.println(enc);
}catch(EOFException e){
}
}
}


I am getting the error that it cannot find the symbol 'in' or 'out'

Answer

You should declare them first.

public static void main(String[] args)throws Exception {
    DataOutputStream out = null; 
    DataInputStream in = null;
    try{
        out = new DataOutputStream(new BufferedOutputStream(new FileOutputStream("dec.dat")));
        in = new DataInputStream(new BufferedInputStream(new FileInputStream("enc.dat")));

        String enc=in.readUTF();
        System.out.println(enc);
    }catch(EOFException e){
    }
}
