Java provides several built-in methods for sorting lists, each utilizing different sorting algorithms. For example, theCollections.sort()method uses a variant ofthe MergeSort algorithm, which is efficient but can be overkill for small lists. On the other hand, theArrays.sort()method uses a vari...
Java Predicate is a functional interface as part of the java.util.function package which acts as a general predicate assigned as a target to the lambda expression for referencing any method or evaluating any Boolean based function with the Boolean values of true or false being assigned as a tar...
but let’s design an alternate way of delegating the logic to the enum itself. we’ll define methods for each of the enum values and do the calculation
In Java, it is possible to break out of aloopfrom outside the loop’s function by using a labeled break statement. This can be useful when you need to stop the loop based on aconditionoutside of the loop, such as a user input or asystemevent. In this blog post, we will explore ...

Secrets are strings of characters that shouldn't be shared with the outside world: they could be database passwords, private encryption keys, personal access tokens, and so on. For enhanced security, many people also consider that anything that could help an attacker should be considered a secr...
Writing repetitive tasks is common in programming. One option is to write the same or similar code as many times as needed to have a block of code executed repetitively. This approach is far from perfect because it will create a lot of duplicate code that is hard to read and maintain. A...
. The suspension occurs in the native code (Native), and the virtual machine does not know it at all. Unlike methods such as Java's sleep() or wait() that are explicitly called, the virtual machine can know the true state of the thread, but for the native code. Suspended, the ...
These results show that, for this example, disabling the interpreter (i.e., -Xcomp) causes a huge increase in the execution time when compared to the default JVM options. The reason, as explained above, is that many methods will not be executed enough to amortize the cost of their compil...
Many times we encounter decision constructs which end up doing the similar operation in each branch. This provides an opportunity to extract a factory method which returns an object of a given type and performs the operation based on the concrete object behavior. ...
