String intern() Method

The intern() method on strings is used to check canonical presentation of the given string. It returns the standard representation of the given string.

Syntax:

string_Name.intern()

Parameters: The method is a parameter-less method i.e., it does not accept any parameter.

Return Value: It returns a string which is a canonical presentation of the given string.

Example 1:

object myObject {
    def main(args: Array[String]) {
        val string1 = "includehelp\t is a great place to learn programming. \n They have the best programming tutorials"
        val canonicalString = string1.intern()
    
        println("The standard string is \n'" + canonicalString + "'")
    }
}

Output:

The standard string is 
'includehelp	 is a great place to learn programming. 
 They have the best programming tutorials'
