Opening and reading files with Java JDK 1.0.x #Java Short Notes

Leave a comment 

   1. Open the file with the File class;   2. Create a FileInputStream object using the File object;   3. Convert the FileInputStream to a BufferedInputStream to greatly increase file reading speed;   4. Convert the BufferedInputStream to a DataInputStream; the methods of DataInputStream        give a fair amount of flexibility in        reading the data.   5. Read the file until the endFile f = new File("mydata.txt"); FileInputStream fis = new FileInputStream(f); BufferedInputStream bis = new BufferedInputStream(fis); DataInputStream dis = new DataInputStream(bis);  String record = null; try {    while ( (record=dis.readLine()) != null ) {       //       // put your logic here to work with "record"       //    } } catch (IOException e) {    //    // put your error-handling code here    // }
