Java Tips and Best practices to avoid NullPointerException in Java Applications

A NullPointerException in Java application is the best way to solve it and that is also key to write robust programs that can work smoothly. As it said “prevention is better than cure”, same is true with nasty NullPointerException. Thankfully by applying some defensive coding techniques and the following contracts between multiple parts of an application, you can avoid NullPointerException in Java to a good extent. By the way, this is the second post on NullPointerException in Javarevisited, In the last post, we have discussed the common causes of NullPointerException in Java and in this tutorial,  we will learn some Java coding techniques and best practices, which can be used to avoid NullPointerException in Java.

Why use Underscore in Numbers from Java? Underscore in Numeric Literals Example

JDK 1.7 release had introduced several useful features, despite most of them being syntactic sugar, there use can greatly improve readability and code quality. One such feature is the introduction of underscores in numeric literals . From Java 7 onwards you can write a long digit e.g. 10000000000 to a more readable 1 0_000_000_000 in your Java source code. One of the most important reasons for using an underscore in numeric literal is avoiding subtle mistakes that are hard to figure out by looking at code. It's hard to notice a missing zero or extra zero between 10000000000 and 1000000000 , than 10_000_000_000 and 1_000_000_000 .

3 ways to convert String to Boolean in Java? Examples

You can convert a String object to a Boolean object or boolean primitive by using the Boolean.valueOf() and Boolean.parseBoolean() method. The steps are similar rot converting to String to other data types  like  String to Integer and String to Long . You can use the  valueOf() method to convert String to Boolean object and parseBoolean() method to convert a given string to a boolean primitive value. Internally, valueOf() also uses parseBoolean() for parsing String but on top of that it also provides caching e.g. it can return Boolean.TRUE and Boolean.FALSE cached value for "true" and " false" strings.
