The hashCode() method of LinkedHashSet in Java is used to get the hashCode value for this instance of the LinkedHashSet. It returns an integer value which is the hashCode value for this instance of the LinkedHashSet.
Syntax:
public int hashCode()
Parameters: This function has no parameters.
Returns: The method returns an integer value which is the hashCode value for this instance of the LinkedHashSet.
Below examples illustrates the LinkedHashSet.hashCode() method:
Example 1:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
LinkedHashSet<Integer> LHS
= new LinkedHashSet<Integer>();
LHS.add( 1 );
LHS.add( 2 );
LHS.add( 3 );
LHS.add( 4 );
System.out.println( "LinkedHashSet: "
+ LHS);
System.out.println( "HashCode value: "
+ LHS.hashCode());
}
}
|
Output:
LinkedHashSet: [1, 2, 3, 4]
HashCode value: 10
Example 2:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
LinkedHashSet<String> LHS
= new LinkedHashSet<String>();
LHS.add( "Geeks" );
LHS.add( "For" );
LHS.add( "ForGeeks" );
LHS.add( "GeeksForGeeks" );
System.out.println( "LinkedHashSet: "
+ LHS);
System.out.println( "HashCode value: "
+ LHS.hashCode());
}
}
|
Output:
LinkedHashSet: [Geeks, For, ForGeeks, GeeksForGeeks]
HashCode value: -482506029
