The following Code is to check whether the date entered by the user is a valid date or not. Within the Code, 'Date()' class is only used to get the current system date and the other things're done by simple logic. Code is as follow:- import java.util.*; public class DateValidation{     Scanner scan=new Scanner(System.in);     String mon, da, yea, day3, day4, month3, month4, year7, year8, year9, year10, year11, year12, year5, year6;     char month1, month2, day1, day2, year1, year2, year3, year4, date2;     String date;     int month, day, year;     public void input(){         try{             System.out.println("Enter the date in dd/mm/yyyy format:- ");             date=scan.nextLine();         }  ...

The following Code is to convert all the lower case letters to upper and upper case to lower. 'StringBuffer' Class is used because 'String' class is immutable but the 'StringBuffer' class is mutable. Which means that once the value stored in the 'String' type variable, it's value can't be changed but in 'StringBuffer' it can be changed. Code:- import java.util.*; public class CaseConversion {     int i;     String string;     char casse;     String temp;     Scanner scan = new Scanner(System.in);     public void input() {         try {             System.out.println("Enter any String: ");             string = scan.nextLine();         } catch (Exception e) {         ...

Have you ever been poked on Facebook and wondered exactly what it meant? Well, in this article, we will take a look at the meaning of a Facebook poke. It might just mean much more than you think. Whenever I go on Facebook, I see a little portion of the screen saying that people have poked me. Facebook claims that a poke can be used "to say hello" to your friends. Thus, I see this poke feature on Facebook as a way that my friends are saying, "Hello, I am thinking about you and I miss you." Thus, I think a poke feels pretty good. After you receive a poke, you then have the option of poking back. This could be translated as a way of saying, "Thanks for thinking of me. I feel the same way." However, this is just the surface meaning of a poke on Facebook, but if we dig deeper, we may find that a Facebook poke means much more. Such was the case with my friend Bob. Bob recently asked me, "Richard, what does a Facebook poke mean...
