Java SQL Timestamp setNanos() function with examples Last Updated : 16 Jun, 2022 Summarize Comments Improve Suggest changes Share Like Article Like Report The setNanos() function is a part of Timestamp class of Java SQL.The function is used to set the fractional part of the second's value of the Timestamp Object. The function sets the object's Nanos value to the given value.Function Signature: public void setNanos(int t) Syntax: ts1.setNanos(l); Parameters: The function accepts int value t as parameter which is the nanoseconds value to be set.Return value: The function does not return any value.Exception: The function throws IllegalArgumentException if the parameter passed is less than 0 or greater than 999999999 Below examples illustrate the use of setNanos() functionExample 1: Create a timestamp and use the setNanos() to set the fractional part of timestamp object. Java // Java program to demonstrate the // use of setNanos() function import 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 new timestamp object System.out.println("New Timestamp time : " + ts.toString()); } catch (IllegalArgumentException e) { // Display the error if any error has occurred System.err.println(e.getMessage()); } } } Output: Timestamp time : 1970-01-01 00:00:10.0 New Timestamp time : 1970-01-01 00:00:10.001 Example 2: Create a timestamp and use the setNanos() to set the fractional part of timestamp object and pass negative int value as parameter. Java // Java program to demonstrate the // use of setNanos() function import 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 new timestamp object System.out.println("New Timestamp time : " + ts.toString()); } catch (IllegalArgumentException e) { // Display the error if any error has occurred System.out.println(e.getMessage()); } } } Output: Timestamp time : 1970-01-01 00:00:10.0 nanos > 999999999 or < 0 Reference: https:// docs.oracle.com/javase/7/docs/api/java/sql/Timestamp.html Comment More infoAdvertise with us Next Article Java SQL Timestamp before() function with examples A andrew1234 Follow Improve Article Tags : Java Java-Functions Java-Sql package Java-TimeStamp Practice Tags : Java Similar Reads Java SQL Timestamp setTime() function with examples The setTime() function is a part of Timestamp class of Java SQL.The function is used to set the time of the Timestamp object.
