How to ask Questions Smartly

I'm astonished that you actually expected good quality answers by just pasting your code without an ounce of detail specifying what your issue is.

For anyone willing to investigate further, here's the code in a readable format:

import java.util.Comparator;
import java.util.Iterator;
import java.util.TreeSet;
 
public class MyComp implements Comparator {
 
    public int compare(Object o1, Object o2) {
        Temp t1 = (Temp) o1;
        Temp t2 = (Temp) o2;
        if (t1.salary > t2.salary) {
            return 1;
        } else if (t1.salary < t2.salary) {
            return -1;
        } else {
            return 0;
        }
    }
 
    public static void main(String... s) {
        Comparator m = new MyComp();
        TreeSet ts = new TreeSet(m);
        ts.add(new Temp(10));
        ts.add(new Temp(20));
        ts.add(new Temp(30));
        Iterator i = ts.iterator();
        while (i.hasNext()) {
            Temp t = (Temp) i.next();
            System.out.println(t.salary);
        }
    }
}
 
class Temp {
    int salary;
    Temp(int salary) {
        this.salary = salary;
    }
}

And for the record, Code I just pasted is working, by adding parenthesis and adding a space to else if.
