The hashCode() method of SortedSet in Java is used to get the hashCode value for this instance of the SortedSet. It returns an integer value which is the hashCode value for this instance of the SortedSet.
Syntax:
Java
Java
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 Set. Note: The hashCode() method in SortedSet is inherited from the Set interface in Java. Below examples illustrates the SortedSet.hashCode() method: Example 1:
// Java code to demonstrate the working of
// hashCode() method in SortedSet
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// creating an Set
SortedSet<Integer> arr
= new TreeSet<Integer>();
// using add() to initialize values
// [1, 2, 3, 4]
arr.add(1);
arr.add(2);
arr.add(3);
arr.add(4);
// print Set
System.out.println("Set: " + arr);
// Get the hashCode value
// using hashCode() value
System.out.println("HashCode value: "
+ arr.hashCode());
}
}

// creating an Set10
SortedSet<Integer> arr11
= new TreeSet<Integer>();12

// using add() to initialize values14
// [1, 2, 3, 4]15
arr.add(1);16
arr.add(2);17
arr.add(3);18
arr.add(4);19
20
// print Set21
System.out.println("Set: " + arr);22
23
// Get the hashCode value24
// using hashCode() value25
System.out.println("HashCode value: "26
+ arr.hashCode());27
}28
}
Output:
Example 2:
Set: [1, 2, 3, 4] HashCode value: 10
// Java code to demonstrate the working of
// hashCode() method in Set
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// creating an Set
SortedSet<String> arr
= new TreeSet<String>();
// using add() to initialize values
// [Geeks, For, ForGeeks, GeeksForGeeks]
arr.add("Geeks");
arr.add("For");
arr.add("ForGeeks");
arr.add("GeeksForGeeks");
// print Set
System.out.println("Set: " + arr);
// Get the hashCode value
// using hashCode() value
System.out.println("HashCode value: "
+ arr.hashCode());
}
}
