Java serial 96-FileInputStream analytical method, the content of the entire cycle of the output

Parse available \ skip \ close \ read (int [] a) Method using the read and print out all the method loops content.

 

package com.bjpowernode.java_learning;

import java.io.*;

public class D96_1_CircleRead {

  public static void main(String[] args) throws Exception{

    FileInputStream fis = new FileInputStream("C:\\Users\\lenovo1\\Workspaces\\MyEclipse CI\\Java_learning\\src\\com\\bjpowernode\\java_learning\\D95_1_FileInputStreamAnalysis.java");

    byte[] bytes = new byte[1024];

    //1.available方法

    System.out.println(fis.available());

    System.out.println("===========");

    // 2.skip method 

    fis.skip ( 2); // skip reading two bytes 

    System.out.println ( "===========" );    

    // 3. print cycle the contents of 

    the while ( to true ) { 

      int TEMP = fis.read (bytes); 

      IF (TEMP == -. 1) BREAK ; 

      // convert byte array into a string of valid data 

      of System.out.print ( new new string (bytes , 0 , TEMP)); 

      // note is taken here of the string, here we need to know read return value of this method, we create the equivalent of a so array, each for storing 

      // read 1KB, and 1kb, 1kb output. The reason for using a 0 to temp, front read when they are to say, the array can be filled, but when read 

      // when the last time, there will occupy part of an array, if we use fixed-length 1024 it will put the last part of the contents of the print out 

    }

   

    // 4.int Read (byte [] B) from the input data stream up to b.length bytes read into the byte array 

   

    System.out.println ( "===========" ); 

    // can be seen that a method is available for viewing also the remaining number of bytes is not reading 

    System.out.println (fis.available ()); 

    // 5. the remember to close the stream 

    fis.close (); 

  }
