Java: Get an element in a tree set which is strictly greater than the given element

Last update on March 12 2025 13:34:23 (UTC/GMT +8 hours)

Write a Java program to get the element in a tree set strictly greater than or equal to the given element.

Sample Solution:

Java Code:

import java.util.TreeSet;
import java.util.Iterator;

  public class Exercise12 {
  public static void main(String[] args) {
 // creating TreeSet 
   TreeSet <Integer>tree_num = new TreeSet<Integer>();
   TreeSet <Integer>treeheadset = new TreeSet<Integer>();
     
   // Add numbers in the tree
   tree_num.add(10);
   tree_num.add(22);
   tree_num.add(36);
   tree_num.add(25);
   tree_num.add(16);
   tree_num.add(70);
   tree_num.add(82);
   tree_num.add(89);
   tree_num.add(14);
   
   System.out.println("Strictly greater than 76 : "+tree_num.higher(76));
   System.out.println("Strictly greater than 31 : "+tree_num.higher(31));
   }    
}

Sample Output:

Strictly greater than 76 : 82                                          
Strictly greater than 31 : 36

• Write a Java program to use the higher() method on a TreeSet to get the least element strictly greater than a given value.
• Write a Java program to implement a lambda expression that returns the element strictly greater than a specified target using TreeSet methods.
• Write a Java program to compare the higher() method’s result with a custom loop that finds the next greater element.
• Write a Java program to handle cases when no element is strictly greater than the given value and print a fallback message.
