title: Unreachable code in eclipse
body: <p>What does the following mean?</p>
  
  <pre><code>Exception in thread "main" java.lang.Error: Unresolved compilation problem:
  Unreachable Code    
  at mycode.sample.main(sample.java:24) 
  </code></pre>
  
  <p>I'm hoping I can find the line where the error occurred. I thought "24" is the line, but I only have 23 lines of code in my project.</p>
  
  <p>Here's the project code</p>
  
  <pre><code>package mycode;
  import java.io.*;
  
  public class sample {
    int first;
    int second;
  
    public sample (int fir,int sec)
    {
      fir = first;
      sec = second;
    }
  
    public void add()
    {
      System.out.println(first+second);       
    }
  
    public static void main(String[] args) throws IOException
    {
      BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
      int f = Integer.parseInt(reader.readLine());
      // int s =  Integer.parseInt(reader.r   eadLine());
      sample sample2 = new sample(f,100);
      sample2.add();
    } 
  }   
  </code></pre>
  
  <p>I would like to understand this error message.
  Thanks in advance.</p>
