![]() There are several ways to initialize an object in Java. What are the various ways to initialize an object in Java? The main difference is that the Old Generation space is much larger than the Young Generation space, because it needs to be able to accommodate more objects. The Young Generation space is used for new objects, and the Old Generation space is used for objects that have been around for a while. What’s the main difference between Young Generation and Old Generation spaces in the Java Heap? For example, you might have a class called “Dog” that includes characteristics such as “breed” and “color.” An object would be a specific dog, such as a golden retriever. In other words, a class is a template for an object, and an object is a specific instance of a class. Can you explain the difference between objects and classes? For the CMS GC, you will need to set the -Xmx and -Xms parameters to different values. To configure memory parameters for the parallel GC, you will need to set the -Xmx and -Xms parameters to the same value. The most common GC types in Java are the parallel GC and the CMS GC. Can you give me an example of how to configure memory parameters for different GC types in Java? This helps to free up memory and keep the program running smoothly. Can you explain what a garbage collection (GC) cycle in Java is?Ī garbage collection cycle in Java is when the JVM (Java Virtual Machine) runs a GC (garbage collection) algorithm to identify and remove objects that are no longer needed by the program. The heap is also where garbage collection takes place. ![]() When an object is created, it is stored in the heap. The Java heap is the area of memory where Java objects are stored. Here are 20 commonly asked Java Heap interview questions and answers to prepare you for your interview: 1. Java Heap Interview Questions and Answers ![]() In this article, we discuss the most commonly asked Java Heap questions and how you should respond. Reviewing common questions and their answers ahead of time can help you feel more confident and prepared for your interview. When interviewing for a position that requires Java Heap knowledge, you can expect questions about how the system works and how to properly use it. Java Heap is a memory management system for the Java programming language. ![]()
