Top 5 Courses to learn JVM Internals, Memory Management, GC and Performance Tuning in Java in 2022

For a senior Java developer, it's essential to know how JVM works and how to troubleshoot issues with respect to memory, most notably memory leaks in Java applications and servers like Tomcat. You might be thinking, how come memory leaks in Java? Isn't memory is managed by JVM and Garbage collector? Well, that's true, but poor coding or just a bit of carelessness can cause memory leaks in Java. If you don't know how to configure JVM, troubleshoot memory-related problems on the heap, and stack, you will struggle at a higher level. That's why it's essential for experienced Java developers to spend some time learning these advanced skills as their experience grows.

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.
