read and skip number of bytes in java using FileInputStream

import java.io.*; class inputstrm { public static void main(String [] args) throws Exception { int size; FileInputStream inputstrm = new FileInputStream("inputstrm.java"); //to get size in bytes System.out.println("available bytes" +(size = inputstrm.available())); //to read first 50 bytes System.out.println("reading 50 bytes"); byte bytearray[] = new byte[50]; if(inputstrm.read(bytearray) !=50) { System.out.println("could not get 50 bytes"); } System.out.println(new String(bytearray,0,50)); //skip 50 bytes System.out.println("skipped 50 bytes"); inputstrm.skip(50); //read after skipping 50 bytes System.out.println("reading 50 bytes"); if(inputstrm.read(bytearray) !=50) { System.out.println("could not get 50 byte"); } System.out.println(new String(bytearray,0,50)); //close file inputstrm.close(); } }
