How do you ensure ordering between multiple threads in Java? Of course you cannot use higher order concurrency utilities like CyclicBarrier and CountDownLatch. Well, you can use join method to do that. Join() method allows a Thread to wait until another thread finishes its execution. #java

If you think that calculating number of days between two dates in Java is easy then you are WRONG. It's not as easy as it looks, unless you are using JodaTime or running on Java 8. In this article, we will see why simple way of calculating difference between dates using getTime() method is broken and why you need library like Joda. #java   #programming

How about solving Producer Consumer Problem using Lock and Condition classes from java.util.concurrent package?
One of the better ways to learn new concept is solving old problem with new tools http://javarevisited.blogspot.sg/2015/06/java-lock-and-condition-example-producer-consumer.html
#Java   #Multithreading  
You can also solve producer consumer problem by using new lock interface and condition variable instead of using synchronized keyword and wait and notify methods. Lock provides an alternate way to achieve mutual exclusion and synchronization in Java. Advantage of Lock over synchronized keyword ...

java.sql.SQLException: No suitable driver found for jdbc:XXX error comes due to malformed JDBC URL. It's most likely the protocol part which is not matching with the JDBC driver in your CLASSPATH. For example, you can connect to SQL SERVER database from Java using jTDS and SQLJDBC4 driver. If there is mismatch between URL and driver JAR in classpath, you will see this exception. #java   #JDBC

Data Structure and Algorithms are probably THE most important topic for any programmer, but, unfortunately, not all programmers are well versed on this. One reason of this lacking could be that programmer often think DS and Algorithm from academics and text book perspective and not about a tool to solve real world programming problems. Since many programmers not even read a single book outside of text book I have shared some great books to learn and improve your knowledge on DS and Algorithms. Let us know, how did you find this list. #Programming   #Algorithm

Difference between type 1, 2, 3 and type 4 JDBC driver in Java?
There are four types of JDBC drivers in Java, Do you know why Java has so many drivers? Their journey starts from portability and performance reasons, type 1 is the oldest and has lowest portability and type 4 is the latest one and highly portable because it uses Java JAR file which is platform independent.   http://java67.blogspot.sg/2015/07/difference-between-type-1-2-3-and-4-jdbc-drivers-java.html #Java   #JDBC
