How do I write class names in Java?

Java 8Object Oriented ProgrammingProgramming

While writing class names you need to keep the following points in mind.

  • You shouldn’t use predefined or existing class names as the name of the current class.
  • You shouldn’t use any Java keywords as class name (with the same case).
  • The First letter of the class name should be capital and remaining letters should be small (mixed case).
class Sample
  • Likewise, first letter of each word in the name should be capital an remaining letters should be small.
class Test
  • Keeping interface names simple and descriptive is suggestable.
  • Better not to use acronyms while writing class names.

Example

Live Demo

public class Test {
   public void sample() {
      System.out.println("This is sample method");   
   }
   public void demo() {
      System.out.println("This is demo method");   
   }
   public static void main(String args[]) {
      Test obj = new Test();
      obj.sample();
      obj.demo();
   }
}

Output

This is sample method
