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
