Question

In writing integers to a file you need to connect 2 streams together to accomplish this task. Below show the code you might use to connect 2 stream classes together. (Use a FileOutputStream and a DataOutputStream)

Answer 1

Code:

public class FileExample {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
     try{    String path1="E:\\intwritingex.txt" ;
             FileOutputStream fout=new FileOutputStream(path1);    //path1 is file pathname
             DataOutputStream ds = new DataOutputStream(fout); //connectting ds stream to file stream
        ds.writeInt(1); //writing usig ds as integer not possible in ordinary file much easily integer is wirtten in as hexacedimal in file not decimal
        ds.flush(); //FLUSH IS USED FOR FORCED WRITING
     
        ds.close() ;//closoiign data stream
        fout.close();//closing file steam
        System.out.println("operations perfomed succesfully");
            }catch(Exception e){System.out.println("FILE CANNOT BE OPENED");}  
      }//end of main  
    }//end of class

Word of caution datastream writeInt writes integer in hexadecimal format to file
