Java Character charCount() method

The charCount() method of character class is used to determine the total number of char values needed to represent the specified character. As the name suggests, it counts the total char values.

Syntax

Parameter

The method requires a codePoint. A codePoint is a character to be tested.

Return Value

If the given character is equal to or greater than 0X10000, the method returns 2. Otherwise the method returns 1.

Example 1

public class CharactercharCountMethodExample1 {
    public static void main(String[] args) {
	int obj1 = 59;
	int obj2 = 1546719;
// Check the number of char values needed and print the values.
       int r1 = Character.charCount(obj1);
System.out.println("The first object " + obj1 + " can be represented by "+ r1 + " char values");
	int r2 = Character.charCount(obj2);
System.out.println("The second object " + obj2 + " can be represented by " + r2 + " char values");
    }
}

Test it Now

Output:

The first object 59 can be represented by 1 char values
The second object 1546719 can be represented by 2 char values

Example 2

public class CharactercharCountMethodExample2 {
	public static void main(String[] args) {
// Case 1: codePoint is less than 0X10000. It will return 1.   
	int a = Character.charCount(50);
  System.out.println("The value comes to be:");
  System.out.println(a);
// Case 2: codePoint is equal to 0X10000. It will return 2.
	int b = Character.charCount(589);
  System.out.println("The value comes to be:");
  System.out.println(b);
// Case 3: codePoint is greater than 0X10000. It will return 2.
	int c = Character.charCount(67890);
  System.out.println("The value comes to be:");
  System.out.println(c);
   }
}

Test it Now

Output:

The value comes to be:
1
The value comes to be:
1
The value comes to be:
2

Example 3

import java.util.Scanner;
public class CharactercharCountMethodExample3{
   public static void main(String[] args)
     {
      	Scanner scanner1 = new Scanner(System.in); 
	 System.out.println("Enter the first number");
        int a1= scanner1.nextInt();
        System.out.println("The value comes to be: "+   +Character.charCount(a1));
       Scanner scanner2 = new Scanner(System.in); 
        System.out.println("Enter the second number");
        int a2= scanner2.nextInt();
        System.out.println("The value comes to be:   "+   +Character.charCount(a2));
      Scanner scanner3 = new Scanner(System.in); 
	System.out.println("Enter the third number");
       int a3= scanner3.nextInt();
       System.out.println("The value comes to be:  "+  +Character.charCount(a3));       
	}
}

Output:

Enter the first number
67
The value comes to be: 1
Enter the second number
78
The value comes to be:   1
Enter the third number
2456789
The value comes to be:  2
