Java SQL Date setHours(inti) Method

The setHours(int i) method of Java Date class sets the value of hour by overwriting the value of hour represented by this date. This method should not be used because SQL date values do not have the time component and this method is deprecated too. This method overrides setHours in class Date.

Syntax

@Deprecated
public void setHours(int i)

Parameters

i = It is the hour value

Exception

IllegalArgumentException is thrown if this method is invoked.

Example

import java.util.Date;

public class JavaSQLDateSetHoursExample1 {

	
	public static void main(String [] args)
	{
		
		//using deprecate's method alternative
		//using java.util.Date
		System.out.println("!! this output is shown by using java.util.Date as an alternate to deprecated method java.sql.Date ");
		java.util.Date utild=new Date();
		utild.setHours(21);
		int hours=utild.getHours();
		System.out.println("Current time in hours = " + hours);
		
		
		System.out.println("!! this output is shown by using java.sql.Date and proves why this method is deprecated and we can't access time components in java.sql.Date class. ");
		//using java.sql.Date
		//java.sql.Date do not have time components so we can't access the time components
		//Thats why this method is deprecated and it will give IllegalArgumentException because we can't access time components
		long ctm=System.currentTimeMillis();
		java.sql.Date sqld=new java.sql.Date(ctm);
		sqld.setHours(41);;
		int sqlhours=sqld.getHours();
		System.out.println("Current time in Seconds = " + sqlhours);		
	}
}
