Hello guys, if you are wondering how to convert VARCHAR to String in SQL then you are at the right place. In this article, we will cover various techniques to convert String to Integer in all databases - MySQL, Oracle, SQL server and PostgreSQL. To perform tasks or correlations or change between information in a SQL Server data set, the SQL information kinds of those values should coordinate. At the point when the SQL information types are unique, they will go through a cycle called type-projecting. The transformation of SQL information types, in this cycle, can be implied or unequivocal.

Composite Design Pattern Example in Java and Object Oriented Programming
Hello guys, if you are wondering how to use Composite design pattern in Java then you are at the right place. Composite design pattern is another object oriented design pattern introduced by Gang of Four in there timeless classic book Design pattern : Elements of Reusable software. Composite pattern as name suggest is used to compose similar things together, like similar objects. It implements an interface and also contains other objects which implements the same interface, also known as containee. One of the best example of Composite pattern from Java standard library is Swing's container classes e.g. Panel, which not only are Components by themselves, but also contains other components like JButton, Label, JTable etc.

ArrayList.contains(), size(), clear, asList(), subList(), toArray(), and isEmpty() Example in Java
ArrayList in Java is one of the most popular Collection classes. ArrayList is an implementation of the List interface via AbstractList abstract class and provides an ordered and an index-based way to store elements. Java ArrayList is analogous to an array, which is also index-based. In fact, ArrayList in Java is internally backed by an array, which allows them to get constant time performance for retrieving elements by index. Since an array is fixed length and you can not change their size, once created, Programmers, starts using ArrayList, when they need a dynamic way to store object, i.e. which can re-size itself. See the difference between Array and List for more differences.

5 Difference between Hashtable vs HashMap in Java? Answer
Hashtable and HashMap are two hash-based collections in Java and are used to store objects as key-value pairs. Despite being hash-based and similar in functionality there is a significant difference between Hashtable and HashMap and without understanding those differences if you use Hashtable in place of HashMap then you may run into series of subtle programs which is hard to find and debug. Unlike the Difference between ArrayList and HashMap, Differences between Hashtable and HashMap are more subtle because both are similar kinds of collections. Before seeing the difference between HashMap and Hashtable let's see some common things between HashMap and Hashtable in Java.

Top 25 Java Error and Exception Interview Questions Answers
For checked exceptions, the compiler ensures that they are either handled using try-catch, try-finally, or try-catch-finally block or thrown away. If a method, which throws a checked exception like IOException, and doesn't handle them or doesn't declare them in the throws class of the method, a compile-time error will occur. On the other hand, the compiler doesn't do similar checks for an unchecked exception, that's why it is known as un-checked. These are also called runtime exceptions because they extend java.lang.RuntimeException.
