// Declare and initialize a string variable "str" with the value "w3rsource.com".
String str = "w3rsource.com";
// Print the original string.
System.out.println("Original String : " + str);
// Count the number of Unicode code points from index 1 to index 10 in the string.
int ctr = str.codePointCount(1, 10);
// Print the count of Unicode code points from index 1 to index 10 in the string.
