Java Collection, TreeSet Exercises: Compare two tree sets
Java Collection, TreeSet Exercises: Exercise-8 with Solution
Write a Java program to compare two tree sets.
Sample Solution:
Java Code:
import java.util.TreeSet;
import java.util.Iterator;
public class Exercise8 {
public static void main(String[] args) {
// Create a empty tree set
TreeSet<String> t_set1 = new TreeSet<String>();
// use add() method to add values in the tree set
t_set1.add("Red");
t_set1.add("Green");
t_set1.add("Black");
t_set1.add("White");
System.out.println("Free Tree set: "+t_set1);
TreeSet<String> t_set2 = new TreeSet<String>();
t_set2.add("Red");
t_set2.add("Pink");
t_set2.add("Black");
t_set2.add("Orange");
System.out.println("Second Tree set: "+t_set2);
//comparison output in tree set
TreeSet<String> result_set = new TreeSet<String>();
for (String element : t_set1){
System.out.println(t_set2.contains(element) ? "Yes" : "No");
}
}
}
Sample Output:
Free Tree set: [Black, Green, Red, White] Second Tree set: [Black, Orange, Pink, Red] Yes No Yes No
