Character getType() Method in Java with examples

Last Updated : 20 Jun, 2018

The Character.getType(char ch) is an inbuilt method in java that returns a value indicating a character’s general category. This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the getType(int) method.

Syntax:

public static int getType(char ch)

Parameters: The method accepts one parameter ch of character datatype which refers to the character to be tested.

Return value: This method returns a value of type integer representing the character’s general category.

Below programs illustrates the use of Character.getType(char ch) method:
Program 1:

import java.lang.*;
  
public class gfg {
  
   public static void main(String[] args) {
  
  
      // Create 2 character primitives ch1, ch2 and assigning values
      char c1 = 'K', c2 = '%';
  
      // Assign getType values of c1, c2 to int primitives int1, int2
      int int1 = Character.getType(c1);
      int int2 = Character.getType(c2);
  
      String str1 = "Category of " + c1 + " is " + int1;
      String str2 = "Category of " + c2 + " is " + int2;
  
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Output:

Category of K is 1
Category of % is 24

Program 2:

import java.lang.*;
  
public class gfg {
  
   public static void main(String[] args) {
  
  
      // Create 2 character primitives ch1, ch2 and assigning values
      char c1 = 'T', c2 = '^';
  
      // Assign getType values of c1, c2 to inyt primitives int1, int2
     int int1 = Character.getType(c1);
     int int2 = Character.getType(c2);
  
      String str1 = "Category of " + c1 + " is " + int1;
      String str2 = "Category of " + c2 + " is " + int2;
  
      System.out.println(str1);
      System.out.println(str2);
   }
}

Output:

Category of T is 1
Category of ^ is 27

The java.lang.Character getType(int codePoint) is similar to previous method in all the manner, this method can handle supplementary characters.

Syntax:

public static int getType(int codePoint)

Parameter: The method accepts a single parameter codePoint of integer datatype and refers to the character (Unicode code point) to be tested.

Return Value: This method returns a value of type int representing the character’s general category.

Below programs demonstrates the above mentioned method:
Program 1:

// Java program to demonstrate
// the above method
import java.lang.*;
  
public class gfg {
  
   public static void main(String[] args) {
  
      // int primitives c1, c2
      int c1 = 0x0037, c2 = 0x016f;
  
  
      // Assign getType values of c1, c2 to int primitives int1, int2
     int int1 = Character.getType(c1);
     int int2 = Character.getType(c2);
  
      // Print int1, int2 values
      System.out.println(  "Category of c1 is " + int1);
      System.out.println(  "Category of c1 is " + int2);
   }
}

Output:

Category of c1 is 9
Category of c1 is 2

Program 2:

// Java program to demonstrate
// the above method
import java.lang.*;
  
public class gfg {
  
   public static void main(String[] args) {
  
      // int primitives c1, c2
      int c1 = 0x0135, c2 = 0x015f;
  
  
      // Assign getType values of c1, c2 to int primitives int1, int2
     int int1 = Character.getType(c1);
     int int2 = Character.getType(c2);
  
      // Print int1, int2 values
      System.out.println(  "Category of c1 is " + int1);
      System.out.println(  "Category of c1 is " + int2);
   }
}

Output:

Category of c1 is 2
Category of c1 is 2
