Java - Float Class hashCode() Method

Float class hashCode() method: Here, we are going to learn about the hashCode() method of Float class with its syntax and example. By Preeti Jain Last updated : March 21, 2024

Float class hashCode() method

hashCode() method is available in java.lang package.
hashCode() method is used to return hashcode of the Float object.
hashCode() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
hashCode() method does not throw an exception at the time of returning hashcode.

Syntax

public int hashCode();

Parameters

It does not accept any parameter.

Return Value

The return type of this method is int, it returns the hash code for this object.

Example

// Java program to demonstrate the example 
// of int hashCode() method of Float class

public class HashCodeOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float value1 = 30.20f;
        float value2 = 10.20f;

        // It returns hashcode value denoted by this Float f1 object
        // by calling f1.hashCode()
        Float f1 = new Float(value1);

        // Display f1 result
        System.out.println("f1.hashCode(): " + f1.hashCode());

        // It returns hashcode value denoted by this Float f2 object
        // by calling f2.hashCode()
        Float f2 = new Float(value2);

        // Display f2 result
        System.out.println("f2.hashCode(): " + f2.hashCode());
    }
}

Output

f1.hashCode(): 1106352538
f2.hashCode(): 1092825907
