The before() function is a part of Timestamp class of Java SQL.The function returns a boolean value representing whether the Timestamp object occurs before the given Timestamp object.
Function Signature:
public boolean before(Timestamp t)
Syntax:
ts1.before(ts2);
Parameters: The function accepts Timestamp object as parameter which is to be checked.
Return value: The function returns boolean data type representing whether the Timestamp object occurs before the given Timestamp object.
Exception: The function does not throw any exceptions
Below examples illustrate the use of before() function
Example 1: Create two non equal timestamps and check whether the second timestamp occurs before first timestamp or not.
// Java program to demonstrate the// use of before() function  import java.sql.*;  public class solution {    public static void main(String args[])    {          // Create two timestamp objects        Timestamp ts1 = new Timestamp(10003);        Timestamp ts2 = new Timestamp(10001);          boolean b = ts2.before(ts1);          // Check if the second timestamp occurs        // before first timestamp        if (b) {              // If true print that the Second Timestamp            // occurs before the first timestamp            System.out.println("Second Timestamp occurs"                               + " before first timestamp");        }          else {              // If false print that the Second Timestamp            // does not occur before the first timestamp            System.out.println("Second Timestamp does not occur"                               + " before first timestamp");        }    }} |
Second Timestamp occurs before first timestamp
Example 2: Create two equal timestamps and check whether the second timestamp occurs before the first timestamp or not
// Java program to demonstrate the// use of before() function  import java.sql.*;  public class solution {    public static void main(String args[])    {          // Create two timestamp objects        Timestamp ts1 = new Timestamp(10000);        Timestamp ts2 = new Timestamp(10000);          boolean b = ts2.before(ts1);          // Check if the second timestamp occurs        // before first timestamp        if (b) {              // If true print that the Second Timestamp            // occurs before the first timestamp            System.out.println("Second Timestamp occurs"                               + " before first timestamp");        }          else {              // If false print that the Second Timestamp            // does not occur before the first timestamp            System.out.println("Second Timestamp does not"                               + " occur before first timestamp");        }    }} |
Second Timestamp does not occur before first timestamp
