Character.hashCode() in Java with examples

Java.lang.Character.hashCode() is a built-in method in Java which returns a hash code for this Character. The returned hash code is equal to the result of invoking charValue().

Syntax:

public int hashCode()

This function does not accepts any parameter.

Return Value: This method returns a hash code value for this Character.

Below programs illustrate the Java.lang.Character.hashCode() function:

Program 1:

// Java program to demonstrate the 
// function when the value passed in the parameter 
// is a character  
import java.lang.*; 
  
public class Gfg { 
  
    public static void main(String[] args) 
    { 
        // parameter ch 
        char ch = 'B'; 
        // assigns character values 
        Character c = Character.valueOf(ch); 
         
      
        // assign hashcodes of c1, c2 to i1, i2 
        int i = c.hashCode(); 
          
        // prints the character values 
        System.out.println("Hashcode of " + ch + " is " + i); 
    } 
} 

Output:

Hashcode of B is 66

Program 2:

// Java program to demonstrate the 
// function when the value passed in the parameter 
// is a number  
import java.lang.*; 
  
public class Gfg { 
  
    public static void main(String[] args) 
    { 
        // parameter ch 
        char ch = '6'; 
        // assigns character values 
        Character c = Character.valueOf(ch); 
         
      
        // assign hashcodes of ch  
        int i = c.hashCode(); 
          
        // prints the character values 
        System.out.println("Hashcode of " + ch + " is " + i); 
    } 
} 

Output:

Hashcode of 6 is 54
