Java Program to get Sub Set from TreeSet
Let us first create a TreeSet and add elements:
TreeSet<Integer> treeSet = new TreeSet<Integer>(); treeSet.add(10); treeSet.add(20); treeSet.add(30); treeSet.add(40); treeSet.add(50); treeSet.add(60); treeSet.add(70); treeSet.add(80); treeSet.add(90); treeSet.add(100);
Now, let’s say you need to set sub set from 50 to 70, then use the subset() for it:
SortedSet<Integer> sub = treeSet.subSet(50, 70);
System.out.println("Sub Set = " + sub);Example
import java.util.TreeSet;
import java.util.SortedSet;
public class Demo {
public static void main(String[] args) {
TreeSet<Integer> treeSet = new TreeSet<Integer>();
treeSet.add(10);
treeSet.add(20);
treeSet.add(30);
treeSet.add(40);
treeSet.add(50);
treeSet.add(60);
treeSet.add(70);
treeSet.add(80);
treeSet.add(90);
treeSet.add(100);
SortedSet<Integer> sub = treeSet.subSet(50, 70);
System.out.println("Sub Set = " + sub);
sub = treeSet.subSet(80, 90);
System.out.println("Sub Set = " + sub);
sub = treeSet.subSet(10, 90);
System.out.println("Sub Set = " + sub);
}
}Output
Sub Set = [50, 60] Sub Set = [80] Sub Set = [10, 20, 30, 40, 50, 60, 70, 80]
