Java Timestamp compareTo() Method

The compareTo () method of Timestamp class compares this Timestamp object to the given Timestamp object or to the given date object.

Syntax

public int compareTo(Timestamp ts)
public int compareTo(Date o)

Parameters

The parameter 'ts' represents the Timestamp object to be compared to this Timespan object.
The parameter 'o' represents the date to be compared to this Timespan object.

Returns

The compareTo() method of Timestamp class returns :

Integer value 0 if this Timestamp object is equal to given Timestamp object.
A value less than 0 if this Timespan object is before the given argument.
A value greater than 0 if this Timespan object is after the given argument.

Example 1

import java.sql.Timestamp;
public class JavaTimestampCompareToExample1 {
    public static void main(String[] args) {
        Timestamp ts1 = Timestamp.valueOf("2018-09-01 09:01:15");
        Timestamp ts2 = Timestamp.valueOf("2018-09-01 09:01:16");
        //compares ts1 with ts2
        int b3 = ts1.compareTo(ts2);
        if(b3==0){
            System.out.println("Both values are equal");
        }
        else if(b3>0){
            System.out.println("TimeSpan1 value is greater");
        }
        else{
            System.out.println("TimeSpan2 value is greater");
        }
    }
}

Output:

TimeSpan2 value is greater

Example 2

import java.sql.Timestamp;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;
class BirthTime {
    static int i = 1;
    public String name;
    Timestamp ts1;
    BirthTime(String name, Timestamp ts1 ) {
        this.name = name;
        this.ts1=ts1;
    }
    public String toString(){
        return this.name;
    }
}
public class JavaTimestampCompareToExample2 {
    public static void main(String[] args) {
        BirthTime name1 = new BirthTime("Reema", Timestamp.valueOf("2018-09-01 09:01:15"));
        BirthTime name2 = new BirthTime("Geetanjali",Timestamp.valueOf("2018-09-01 09:01:18"));
        int capacity = 100;
        BlockingQueue<BirthTime> queue = new ArrayBlockingQueue<BirthTime>(capacity);
        queue.add(name1);
        queue.add(name2);
            if(queue.poll().ts1.compareTo(queue.poll().ts1)>0){
                System.out.println("Reema's birthTime is greater than Geetanjali");
            }
            else{
                System.out.println("Geetanjali's birthTime is greater than Reema");
            }
    }
}

Output:

Geetanjali's birthTime is greater than Reema

Example 3

import java.sql.Timestamp;
import java.util.Date;
public class JavaTimestampCompareToExample3 {
    public static void main(String[] args) {
        Timestamp ts1 = Timestamp.valueOf("2018-09-03 09:01:15");
        System.out.println("Expire Timespan : "+ts1);
        Date date = new Date();
        System.out.println("Today date : "+date);
        //compares ts1 with date
        int b3 = ts1.compareTo(date);
        if(b3==0){
            System.out.println("Your plan will expire today ");
        }
        else if(b3>0){
            System.out.println("Your plan has not expired. You can still avail our facility.");
        }
        else{
            System.out.println("oops!Your plan has expired\nRecharge fast.");
        }
    }
}

Output:

Expire Timespan: 2018-09-03 09:01:15.0
Today date: Sun Sep 02 20:27:12 IST 2018
Your plan has not expired. You can still avail our facility.
