Comments


  • Comments are basically for documentation purpose.
  • When we write code,for description of code we make use of comments.
  • Comments are ignored by compiler,these are like helping text in your program.

Types of Comments in Java:

  2. Multi-line comment

Single-line comments are start with two forward slashes i.e.//. Whatever written inside // are ignored by compiler.It's only for user understanding.

{

//this is single line comment

System.out.println("hello youtube ");
