1. Introduction to the Problem Statement In Java programming, handling null references is essential for preventing the dreaded NullPointerException. Suppose we have an object, MyObject. Our objective is to determine whether MyObject is null. The expected output is a boolean value indicating the null status of the object. This article explores several methods for checking […]

1. Introduction In Java programming, it’s common to need to print multiple variables for various purposes like debugging, logging, or displaying information to the user. These variables might be of different data types (such as integers, strings, or floats), and our goal is to effectively combine and display them. The expected output is a coherent […]

In this tutorial, we will learn what is == in Java as it is a common lexeme that we will use while developing applications. The == lexeme can be confused with = which is another lexeme of the Java language and we will also learn in detail how the two differ to avoid issues such […]

In this post, we will see how to have multiple classes in one file in java. Introduction You need to have any number of classes in a single Java file, but there is a restriction that you can declare only one Java class as public modifier with the main() method and declare (without public) for […]
