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
