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
