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

public class CharactercodePointCountMethodExample1 {
	public static void main(String[] args) {
		System.out.println("Welcome to our tutorial site:");
		CharSequence seq = "Hello";  
		// Declare offset.
		int offset = 2;
		// Declare count.
		int countValue = 4;		
		int result = Character.codePointCount(seq, offset, countValue);
	     // Print the result.
		System.out.println("The result is given as: " + result);
	
       }
}

Test it Now

Output:

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

Example 2

public class CharactercodePointCountMethodExample2 {
    public static void main(String[] args) {
      System.out.println("The alphabets are: 'a', 'b', 'c', 'd', 'e'");
	 char[] c1 = new char[] { 'a', 'b', 'c', 'd', 'e' };
	 int offset1  = 0, count1 = 4;
	 int res1 = Character.codePointCount(c1, offset1, count1);
System.out.println("The number of Unicode code point for alphabets are " + res1);
System.out.println("The numbers are:  '1', '2', '3', '4', '5'");
	 char[] c2 = new char[] { '1', '2', '3', '4', '5' };
	 int offset2  = 1, count2 = 3;
	 int res2 = Character.codePointCount(c2, offset2, count2);
System.out.println("The number of Unicode code point for numbers are " + res2);
	   }
	}

Test it Now

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

public class CharactercodePointCountMethodExample3{
   public static void main(String args[])
    {
     String str1 = "Hello everyone"; 
     System.out.println("Hello everyone");
     int Total1 = str1.codePointCount(3, 9);
     System.out.println(Total1 + " is generated because method counts the first argument.");
     String str2 = "Everday is a fun day";
     System.out.println("Everyday is a fun day");
     int Total2 = str2.codePointCount(6, 8);
     System.out.println(Total2 + " is generated because method counts the second argument.");
     }
  }

Test it Now

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.

Java Character codePointCount()Method

The codePointCount(CharSequence seq, int beginIndex, int endIndex) method of Character class is used to return the number of Unicode code points in the text range of a particular char sequence. The text range begins from the beginIndex and ends at endIndex.

Syntax

Public static int codePointCount(CharSequence seq, int beginIndex, int endIndex) 

Parameter

The above method requires three parameters:

The char sequence.
The beginIndex is the index to the first char of the text range.
The endIndex is the index after the last char of the text range.

Return Value

The codePointCount(CharSequence seq, int beginIndex, int endIndex) method returns the number of Unicode code points in the specified text range.

Example 4

public class CharactercodePointCountMethodExample4 {
	public static void main(String[] args) {
       // Initialize a new CharSequence object
		CharSequence cs = "This is a unique example!";
	    System.out.println("This is a unique example!");
	// Initialize beginIndex and endIndex
		int beginIndex = 0;
		int endIndex = cs.length();	
		int result = Character.codePointCount(cs, beginIndex,endIndex);
	   System.out.println("The result comes to be:"+result);
	}
} 

Test it Now

Output:

This is a unique example!
The result comes to be:25

Example 5

public class CharactercodePointCountMethodExample5 {
     public static void main(String[] args) { // Initialize a new CharSequence object
	CharSequence cs1 = "This is a unique example!"; System.out.println("This is a unique example!"); 
	// Initialize beginIndex and endIndex
	int beginIndex1 = 0;
	int endIndex1 = cs1.length();	
	int result1 = Character.codePointCount(cs1, beginIndex1,endIndex1);
	System.out.println("The result comes to be:"+result1);
	CharSequence cs2 = "Hello World!";
	System.out.println(cs2);
       int beginIndex2 = 4, endIndex2 = 8;
       int result2 = Character.codePointCount(cs2, beginIndex2, endIndex2);
       String str = "Number of Unicode code points is " + result2;
      System.out.println( str );
        }
}

Test it Now

Output:

This is a unique example!
The result comes to be:25
Hello World!
Number of Unicode code points is 4

Example 6

public class CharactercodePointCountMethodExample6 {
	public static void main(String[] args) {

		// Initialize a new CharSequence object
		CharSequence cs1 = "This is a unique example!";
		System.out.println(cs1);
		// Initialize beginIndex and endIndex
		int beginIndex1 = 0;
		int endIndex1 = cs1.length();	
		int result1 = Character.codePointCount(cs1, beginIndex1,endIndex1);
		System.out.println("The result comes to be: "+result1);
	    CharSequence cs2 = "Java is a high level language!";
		System.out.println(cs2);
		int beginIndex2 = 0;
		int endIndex2 = cs2.length();	
		int result2 = Character.codePointCount(cs2, beginIndex2,endIndex2);
		System.out.println("The result comes to be: "+result2);
		CharSequence cs3 = "Java is based on the cocepts of OOPS!";
		System.out.println(cs3);
		int beginIndex3 = 0;
		int endIndex3 = cs3.length();	
		int result3 = Character.codePointCount(cs3, beginIndex3,endIndex3);
		System.out.println("The result comes to be: "+result3);
	
	}
		
	}

Test it Now

Output:

This is a unique example!
The result comes to be: 25
Java is a high level language!
The result comes to be: 30
Java is based on the cocepts of OOPS!
The result comes to be: 37
