The direct solution is to make sure this catch block never exits

Even so, you are not guaranteed to close FileOutputStream. In real
programs this may cause a problem.

A better way to write the program is:

import java.io.*;

class DataIO {
     public static void main(String[] args) {
         try {
             final FileOutputStream fileOut =
                 new FileOutputStream("test");
             try {
                 DataOutputStream out = new DataOutputStream(f);
                 out.writeDouble(7.6d);
                 out.writeFloat(90.9f);
                 out.writeChars("Ravi");
                 out.flush();
             } finally {
                 fileOut.close();
             }
         } catch (FileNotFoundException exc) {
             System.out.println(exc);
             System.exit(1);
             throw new Error(exc);
         } catch (IOException exc) {
             System.out.println(exc);
             System.exit(2);
             throw new Error(exc);
         }
     }
}
