help with process method to find the length of a string
<p>This is my song application</p>

<pre><code>/* 
 *
 */

public class SongApp{
  public static void main(String[] args){
  Song song1 = new Song();
  song1.setsongLine("While my guitar gently weeps.");
  song1.display();
  song1.process();
  Song song2 = new Song();
  song2.setsongLine("Let it be");
  song2.display();
  }
}
</code></pre>

<p>And this is my support class</p>

<pre><code>/* 
 *
 */

public class Song{
  // data field declaration
  private String songLine;


  /*sets the value of the data field songLine to input parameter value*/
  public void setsongLine(String songLine){      
    this.songLine = songLine;   
  } //end method  

 /*returns the value of the data field songLine */
 public String getsongLine(){      
    return songLine;      
 } //end method


  //method called process
  public String process(){
    int stringLength = songLine.length();
  }
  /*displays formatted songLine information to the console window */  
  public void display(){     
   System.out.println(songLine); 
   System.out.println("Length is :" + process());
  }
}
</code></pre>

<p>So my Question is using the process method i need to print out the length of songLine and then produce an output for e.g Length is: 9. but my process method doesnt seem to work so far</p>
