The getNanos() function is a part of Timestamp class of Java SQL.The function is used to get the fractional part of the seconds value of the Timestamp Object. The function returns the object’s nanos value . Function Signature:
public int getNanos()
Syntax:
ts1.getNanos();
Parameters: The function does not accept any parameter. Return value: The function returns an integer value which is the object’s nanos value Exception: The function does not throw any exception Below examples illustrate the use of getNanos() function Example 1: Create a timestamp and use the getNanos() to get the fractional part of timestamp object.
Java
// Java program to demonstrate the// use of getNanos() functionimport java.sql.*;public class solution { public static void main(String args[]) { try { // Create two timestamp objects Timestamp ts = new Timestamp(10000); // Display the timestamp object System.out.println("Timestamp time : " + ts.toString()); // Set the value of the fractional part // of timestamp object // using setNanos function ts.setNanos(1000000); // Display the timestamp object's // seconds' fractional part System.out.println("New Timestamp time : " + ts.toString()); System.out.println(" Fractional Part :" + ts.getNanos()); } catch (IllegalArgumentException e) { // Display the error if any error has occurred System.err.println(e.getMessage()); } }} |
Timestamp time : 1970-01-01 00:00:10.0 New Timestamp time : 1970-01-01 00:00:10.001 Fractional Part :1000000
Example 2: Create a timestamp and use the getNanos() to get the fractional part of timestamp object and dont set any fractional value of seconds
Java
// Java program to demonstrate the// use of getNanos() functionimport java.sql.*;public class solution { public static void main(String args[]) { try { // Create two timestamp objects Timestamp ts = new Timestamp(10000); // Display the timestamp object System.out.println("Timestamp time : " + ts.toString()); // Display the timestamp object's // seconds' fractional part System.out.println("Fractional Part : " + ts.getNanos()); } catch (IllegalArgumentException e) { // Display the error if any error has occurred System.err.println(e.getMessage()); } }} |
Timestamp time : 1970-01-01 00:00:10.0 Fractional Part : 0
