| JDBC Interview questions answers in Java - 2 to 4 years experienced programmer Posted: 22 Dec 2012 08:26 PM PST JDBC Interview question forms one of the important section in Java Interviews. Similar to multithreading, Collection framework and Garbage collection interview question, JDBC question must be prepared by any Java programmer. Most of questions from JDBC or Java database connectivity comes from API and basic architecture of JDBC which also involves JDBC drivers. A good understanding of JDBC API along with database basics like transactions also help to do well in JDBC interviews. I have collected some of frequently asked JDBC Interview question for quick reference. This will help to revise some important JDBC concepts and also give a chance to explore JDBC API to newcomers. If you have any other JDBC interview question, which has been asked to you or friends, and you think it's good to share among Java community then please share with us. Let's see my 11 questions from JDBC, not so tough but worth preparing. |
| How to check leap year in Java - program example Posted: 21 Dec 2012 11:53 PM PST Write a Java program to find if a year is a leap year or not is a standard Java programming exercise during various Java programming course on school, colleges and various training institutes both online and offline, along with other popular homework's e.g. printing Fibonacci numbers, checking palindromes or finding prime numbers. Just to recap a leap year is a year with 366 days which is 1 extra day than normal year. This extra day comes in month of February and on leap year Feb month has 29 days than normal 28 days. If you are following then you might know that leap year comes in a interval of 4 years. This year 2012 is a leap year and Feb has 29 days, you can check. Now if you are in programming before you might be familiar that there is standard logic to find leap year i.e. if an year is multiple of 400 or multiple of 4 but not multiple of 100 then its a leap year. In addition to this standard logic, you can also use Java's Date, Time and Calendar API to check how many days any year has and by comparing that number with 365 you can find whether that year is leap year or not . In this Java programming tutorial we will both of these example to check if a year is leap year or not. |
