The String Class: (Part 3)

Substring Methods of String class:

Note 1: Make sure that substring is the only String class method in Java, that does not follow Camel-case.
Note 2: Indexes are managed as shown in the following example:
For example: Considering String message = "Welcome to Java";

• Example: (substring ->one argument)

  	class test {
  	public static void main(String ar[]) {
  	String str1 = "Good Morning!";
  	System.out.println(str1.substring(3));
  	// prints d Morning -> from index 3 to end of string
  	System.out.println(str1.substring(0));
  	// prints Good Morning! -> from index 0 to end of string
  	System.out.println(str1.substring(str1.length()-1));
  	// prints ! -> length: 13. So print from index 12 to end of string, that is the last character.
  	}
  	}

• Example: (substring ->two arguments)

  	class test {
  	public static void main(String ar[]) {
  	String str1 = "Good Morning!";
  	System.out.println(str1.substring(3,7));
  	// inclusive of the first argument, and exclusive of last argument.
  	// prints d Mo starting with index 3 to 7-1 (that is till 6)
  	System.out.println(str1.substring(0,str1.length()));
  	// prints Good Morning! starting with index 0 to 13-1 (that is till 12)
  	System.out.println(str1.substring(5,str1.length()));
  	// prints Morning! starting with index 5 to 13-1 (that is till 12)
  	}
  	}
