Java Collection, TreeSet Exercises: Exercise-10 with Solution
Write a Java program to get the element in a tree set which is greater than or equal to the given element.
Sample Solution:
Java Code:
import java.util.TreeSet;
import java.util.Iterator;
public class Exercise10 {
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("Greater than or equal to 86 : "+tree_num.ceiling(86));
System.out.println("Greater than or equal to 29 : "+tree_num.ceiling(29));
}
}
Sample Output:
Greater than or equal to 86 : 89 Greater than or equal to 29 : 36
