Parameters: This method has no argument.
Returns: This method returns the hashCode value for the given map.
Below programs show the implementation of int hashCode() method.
Program 1:
import java.util.*;
public class GfG {
public static void main(String[] args)
{
Properties properties = new Properties();
properties.put( "Pen" , 10 );
properties.put( "Book" , 500 );
properties.put( "Clothes" , 400 );
properties.put( "Mobile" , 5000 );
System.out.println( "Properties: "
+ properties.toString());
System.out.println( "HashCode: "
+ properties.hashCode());
}
}
|
Output:
Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
HashCode: 548388082
Program 2:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
Properties properties = new Properties();
properties.put( 1 , "100RS" );
properties.put( 2 , "500RS" );
properties.put( 3 , "1000RS" );
System.out.println( "Current Properties: "
+ properties.toString());
System.out.println( "HashCode: "
+ properties.hashCode());
}
}

Output:
Current Properties: {3=1000RS, 2=500RS, 1=100RS}
HashCode: 1545792714
