How to Count Lines in a Java Project
Individual lines of code in a Java project may actually all be part of a "line" in the programming sense, depending on how your project is laid out. Knowing how many actual lines are in your application from a programming perspective is critical for developing more efficient and smaller applications. You can use a feature within Java to print out a line number total in any particular program.
