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
