Utilize CLOC(Count Lines of Code) to count lines of code

Requirement
If I would like to count lines of code for each Java program in my Java project, which tool can help me?

Solution
Go to http://cloc.sourceforge.net/ to download exe file (i.e. cloc-1.62.exe).

Assume cloc-1.62.exe had been saved into D:\software
Assume the Java project located in D:\workspace2\ave\ave-webapp\src\main\java

• Step1. open command prompt.
• Step2. Change directory to Java project directory, i.e. D:\workspace2\ave\ave-webapp\src\main\java
• Step3. Execute this command: d:\software\cloc-1.62.exe . --by-file

Check the result:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108
