Java Guava | Longs.hashCode() method with Examples
Longs.hashCode() is a method of Longs Class in Guava Library which is used to return a hash code for a long value. The hashCode is an unique integer value that is calculated by the compiler for an object. It remain the same if the object value does not changes.
Syntax:
public static int hashCode(long value)
Parameter: This method takes a mandatory parameter value which is a long value for which the hashCode is to be found.
Return Value: This method returns an integer value which is the hash code for the specified value.
Below programs illustrate the use of the above method:
Example 1:
// Java code to show implementation of // Guava's Longs.hashCode() method import com.google.common.primitives.Longs; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Using Longs.hashCode() method to // get the hash code for value System.out.println( "HashCode value of 15: " + Longs.hashCode( 15 )); } } |
Output:
HashCode value of 15: 15
Example 2:
// Java code to show implementation of // Guava's Longs.hashCode() method import com.google.common.primitives.Longs; import java.util.Arrays; class GFG { // Driver's code public static void main(String[] args) { // Using Longs.hashCode() method to // get the hash code for value System.out.println( "HashCode value of 10: " + Longs.hashCode( 10 )); } } |
Output:
HashCode value of 10: 10
