The hashCode() method of java.lang.Class class is used to get the hashCode representation of this entity. This method returns an integer value which is the hashCode.
Syntax:
public int hashCode()
Parameter: This method does not accept any parameter.
Return Value: This method returns an integer value which is the hashCode.
Below programs demonstrate the hashCode() method.
Example 1:
// Java program to demonstrate hashCode() method public class Test { public static void main(String[] args) throws ClassNotFoundException { // returns the Class object for the class // with the specified name Class c1 = Class.forName("java.lang.String"); System.out.println("Class represented by c1: " + c1); // hashCode method on c1 System.out.println("HashCode value: " + c1.hashCode()); }} |
Output:
Class represented by c1: class java.lang.String HashCode value: 589431969
Example 2:
// Java program to demonstrate hashCode() method public class Test { public static void main(String[] args) throws ClassNotFoundException { // returns the Class object for the class // with the specified name Class c1 = int.class; System.out.println("Class represented by c1: " + c1); // hashCode method on c1 System.out.println("HashCode value: " + c1.hashCode()); }} |
Output:
Class represented by c1: int HashCode value: 589431969
