Garbage Collection is a feature of Java programming language that automatically manages memory allocation and deallocation for objects created in an eden space.
The Java library includes many standard collection classes that can be used in various situations. Knowing how to select the appropriate collection and when to use it is integral to becoming a skilled Java programmer. The most challenging part of the java programming language is collections. It al...
This would print out the lengths of the given strings. Any interface can be functional interface, not merely those that come with Java. To declare your intention that an interface is functional, use the@FunctionalInterfaceannotation. Although not necessary, it will cause a compilation error if yo...
How Java Garbage Collection Works No matter what implementation of the garbage collector we use, to clean up the memory, a short pause needs to happen. Those pauses are also calledstop-the-worldevents or STW in short. You can envision your JVM-based application’s working cycles in the foll...

To use HashMap effectively in Java applications, it’s important to understand its principles and functionality. Now, let’s delve into them in greater detail. A HashMap in Java is a robust data structure that efficiently stores and retrieves key-value pairs. Falling under the ‘Map’ ...
Hello World Program in Java Output: Swap two numbers without using a temporary variable Output: Conclusion Almost everything we use in our day-to-day life is now connected to Java. Java programming language continues to be one of the top technologies in the industries, and the job demand is...
Garbage collection (GC) is amemoryrecovery feature built into programming languages such asC#andJava. A GC-enabled programming language includes one or more garbage collectors (GC engines) that automatically free up memory space that has been allocated toobjectsno longer needed by the program. The...
Why and when to use an Interfaces? An interface is a reference type in Java. It is similar to class. It is acollectionof abstract methods. It is used to achieve totalabstraction. I believe this is the first question you might expect inJava Interview. Very basic questions but widely used...
However, automatic garbage collection is popular for good reason—manual memory management is cumbersome and slows down the pace of application development. How does garbage collection work in Java? During the garbage collection process, the collector scans different parts of the heap, looking for ...
