body: <p>How to assign a String from a text file into integer array for Java?
  I had saved the integer array into a text file, but now how can I retrieve all the integer array from the text file without any modification? I want the integer array retrieved same as before it stored into the text file. Below is part of my code:</p>
  
  <pre><code>BufferedWriter f1 = new BufferedWriter(new InputStreamReader(new FileInputStream("Input.txt")));
  
  int a[ ] = yes(test, test.length); //go to yes method,return value to array  
  for(int i = 0; i &lt; a.length; i++)  
  {  
      f1.write(a[i]);  
  }  
      f1.close( );  
  
  BufferedReader f2 = new BufferedReader(new InputStreamReader(new FileInputStream("Input.txt")));  
  String src;  
  while((src = f2.readLine( )) != null)  
  {  
      String[ ] s = src;  
      int a[ ] = Integer.parseInt(s);//same with before it saved  
      ... ...  
  }  
  </code></pre>

  How to reserve the originality of the integer array(a[ ]) after saved and retrieved from the text file? Thanks!</p>
