  1. POJava - algorithm to find executable lines of code
    text
    copied!<p>I wrote a java program which scans and finds Executable lines of codes (ELOC), blank lines of codes(BLOC) and comments (CLOC) for only java and c++ codes. Following is my code:</p> <pre><code> if(extension.contains("java") || extension.contains("c++")) { Scanner input = new Scanner(fileObject); while(input.hasNext()) { String s = input.nextLine(); if(s.length()==0) { bloc++; } else if(s.contains("/*") || s.startsWith("/*")) { cloc++; while(!s.contains("*/")) { cloc++; s = input.nextLine(); } } else if(s.contains("//")) { cloc++; } else { eloc++; } }//while System.out.println("ELOC: "+(eloc)); System.out.println("Blank Lines: "+bloc); System.out.println("Comment Lines: "+cloc); } </code></pre> <p>I ran different java and c++ source codes but it does not always give the correct answer. What Can I do to make it better? Is there any java code online that I can use?</p> <p>For this question, I'm only counting the executable lines of codes. If a line looks like following:</p> <pre><code>int x=0;//some comment </code></pre> <p>then the line above should be counted as one executable line. Following is my updated code:</p> <pre><code>String extension=getExtension(fileObject.getName()); if(extension.contains("java") || extension.contains("c++")) { Scanner input = new Scanner(fileObject); String s; while(input.hasNext()) { s = input.nextLine().trim(); eloc++; if(s.equals("")) { bloc++; } if(s.startsWith("//")) { cloc++; } if(s.contains("/*") &amp;&amp; !s.contains("*\\")) { cloc++; while(!s.contains("*/")) { cloc++; eloc++; s = input.nextLine(); } } else if(s.contains("/*") &amp;&amp; s.contains("*\\")) { cloc++; } } System.out.println("Total number of lines: "+eloc); System.out.println("ELOC: "+(eloc-(cloc+bloc))); System.out.println("Blank Lines: "+bloc); System.out.println("Comment Lines: "+cloc); } </code></pre> <p>Any comment/advice will be appreciated..Thanks!</p>
