Java.util.Arrays.hashCode(float[]) Method
Description
The java.util.Arrays.hashCode(float[]) method returns a hash code based on the contents of the specified array. For any two float arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).
Declaration
Following is the declaration for java.util.Arrays.hashCode() method
public static int hashCode(float[] a)
Parameters
a − This is the array whose hash value to compute.
Return Value
This method returns a content-based hash code for a.
Exception
NA
Example
The following example shows the usage of java.util.Arrays.hashCode() method.
package com.tutorialspoint; import java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { // initializing float array float[] fval = new float[] { 32.1f, 55.4f }; // hashcode for value1 int retval = fval.hashCode(); // printing hash code value System.out.println("The hash code of value1 is: " + retval); // value2 for double array fval = new float[] { 11.2f, 78.4f }; // hashcode for value2 retval = fval.hashCode(); // printing hash code value System.out.println("The hash code of value2 is: " + retval); } }
Let us compile and run the above program, this will produce the following result −
The hash code of value1 is: 4072869 The hash code of value2 is: 1671711
