Syntax error Get Sub Set from TreeSet in Java

Get Sub Set from TreeSet in Java

To get the sub set from TreeSet, use the subSet() method. Let us first create a TreeSet and add elements to it −

TreeSet<String> set = new TreeSet<String>();
set.add("78");
set.add("56");
set.add("88");
set.add("54");
set.add("76");
set.add("34");

Let us get the subset now from a range of elements −

SortedSet sorted = set.subSet("54", "76");

The following is an example to get sub set from Java TreeSet −

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String args[]){
      TreeSet<String> set = new TreeSet<String>();
      set.add("78");
      set.add("56");
      set.add("88");
      set.add("54");
      set.add("76");
      set.add("34");
      System.out.println("TreeSet elements...");
      Iterator<String> i = set.iterator();
      while(i.hasNext()){
         System.out.println(i.next());
      }
      SortedSet sorted = set.subSet("54", "76");
      System.out.println("SubSet = " + sorted);
   }
}

Output

TreeSet elements...
34
54
56
76
78
88
SubSet = [54, 56]
