TreeSet Sorting Example

-------------------------------- 

import java.util.TreeSet;

public class TreeSetSortingExample {

public static void main(String[] args) {

// TODO Auto-generated method stub

TreeSet<Integer> ts = new TreeSet<Integer>((I1,I2)->(I1>I2)?-1:(I1<I2)?1:0);

ts.add(10);

ts.add(200);

ts.add(90);

ts.add(77);

ts.add(50);

ts.add(150);

ts.add(40);

System.out.println(ts);

}

}

Solution :

[10, 40, 50, 77, 90, 150, 200]

We are passing the argument in TreeSet<Integer> ts = new TreeSet<Integer>(

);

the compare method values (I1,I2)->(I1>I2)?-1:(I1<I2)?1:0
