Java Character codePointCount() Method

This Method has 2 types of syntax.

Java Character codePointCount(char[]a, int offset, int count) Method

The codePointCount(char[]a, int offset, int count) method is used to return the number of Unicode code points in the sub array of the char array. The offset argument is the index of the first char in the given char array and the count argument indicates the length of the sub array.

Syntax

Parameter

The above method requires three parameters:

• The char array.
• The offset is the index of the first char in the given char array.
• The count is the length of the sub array in the given char.

Return Value

This method returns the number of Unicode code point in the specified sub array.

Example 1

Output:

Welcome to our tutorial site: The result is given as: 2 

Example 2

Output:

The alphabets are: 'a', 'b', 'c', 'd', 'e' The number of Unicode code point for alphabets are 4 The numbers are: '1', '2', '3', '4', '5' The number of Unicode code point for numbers are 3 

Example 3

Output:

Hello everyone 6 is generated because method counts the first argument. Everyday is a fun day 2 is generated because method counts the second argument.
