title: How to change the value of array elements
body: <pre><code>int A = 300;
  int B = 400;
  int C = 1000;
  int D = 500;
  
  int []abcd = {A,B,C,D};
  Arrays.sort(abcd);   // the sequence of array elements will be {300, 400, 500,1000}
  </code></pre>
  
  <p>I wanted to change the value of the variables A,B,C,D according to their location in the array after sorting.</p>
  
  <p>e.g variable A is located at index 0, so the value of A change to 1 instead of 300,
      variable B is located at index 1, so the value of B change to 2 instead of 400,
      variable D is located at index 2, so the value of D change to 3 instead of 500,
      variable C is located at index 3, so the value of C change to 4 instead of 1000,</p>
  
  <p>The final value of the variable will be: 
  A = 1;
  B = 2;
  C = 4;
  D = 3;</p>
