Binary Confusion

[kyle_maddisson]

Hi all,

I have a rather vexing problem. I am trying to read in a karel++ .wld (world) file which should be a list of integers stored in 32 bit big-endian format. So after I got this code running it is printing out numbers with decimals in them. How can this be? I tried attaching the world file but couldn't do it.

/* FILE: ReadBinary.java */

/* This program writes some Java primitive data types in their portable
binary format.
*/
import java.io.IOException;
import java.io.DataInputStream;
import java.io.FileInputStream;

public class WorldReader{

public static void main(String args[ ])
{
DataInputStream input = null;
int count;
String fileName = "Third.wld";

// Open the file
try {
input = new DataInputStream(
new FileInputStream(fileName));
}
catch (IOException e) {
System.err.println("Unable to open file " + fileName +
"\n" + e.toString( ));
System.exit(1);
}

try{
double value = input.readDouble( );
System.out.println("Value read in: " + value);
value = input.readDouble( );
System.out.println("Value read in: " + value);
}
catch (IOException io) {
System.err.println("Error during write to file " +
fileName + "\n" + io.toString( ));
System.exit(1);
}
try {
input.close( );
System.exit(0);
}
catch (IOException io) {
System.err.println("Error closing file " +
fileName + "\n" + io.toString( ));
System.exit(1);
}
}
}

If the file contains integers why are you reading the data in as doubles?

I have no idea, thanks.
