Java Timestamp before() Method

The before() method of Timestamp class returns Boolean value true if this Timestamp object is earlier than given Timestamp object.

Syntax

Parameters

The parameter 'ts' represents the Timestamp to compare with.

Returns

The before() method of Timestamp class returns :

Boolean value true if this Timestamp object is earlier than given Timestamp object.
Else, it returns false.

Example 1

import java.sql.Timestamp;
public class JavaTimestampBeforeExample1 {
    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");
        //returns Boolean value true if this ts1 comes earlier than given ts2
        System.out.println("Boolean value returned : "+ts1.before(ts2));
    }
}

Output:

Boolean value returned : true

Example 2

import java.sql.Timestamp;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;
class Age {
    static int i = 1;
    public String name;
    Age(String name) {
        this.name = name;
    }
    public String toString(){
        return this.name;
    }
}
public class JavaTimestampBeforeExample2 {
    public static void main(String[] args) {
        Age name1 = new Age("Reema");
        Age name2 = new Age("Geetanjali");
        int capacity = 100;
        BlockingQueue<Age> queue = new ArrayBlockingQueue<Age>(capacity);
        queue.add(name1);
        queue.add(name2);
        Timestamp ts1 = Timestamp.valueOf("2018-09-01 09:01:15");
        Timestamp ts2 = Timestamp.valueOf("2018-09-01 09:01:16");
        if(ts1.before(ts2)){
            System.out.println(queue.poll()+" is greater than "+queue.poll());
        }
        else{
            System.out.println(queue.poll()+" is younger than "+queue.poll());
        }
    }
}

Output:
