Introduction Core Java (J2SE) and Advanced Java are the two components that make up the Java programming language (JEE). The foundations of the Java programming language, including its data types, functions, operators, loops, threads, and exception handling, are discussed in the "core Java" section of this book. It is used in the process of developing apps for widespread usage. Whereas Intermediate Java focuses on more advanced topics, such as database connection, networking, Servlet, web services, and so on, Advanced Java addresses more fundamental ideas. In this article, we will talk about what advanced Java is, and the concepts of advanced ... Read More

Generating strings that include characters and numbers is a common task in programming. Java provides several ways to generate such strings, and in this article, we will discuss some of the ways to generate strings using characters and numbers in Java. We will cover different approaches to generate random strings and string permutations using characters and numbers. Approach 1: Using Random Class to Generate Random Strings The Random class in Java provides a convenient way to generate random numbers and characters. We can use this class to generate random strings by generating a sequence of random numbers and mapping them ... Read More

Solving interesting pattern problems enhances the understanding of loops. They are essential because they help in building a strong foundation of a particular programming language. There are various kinds of patterns including number-based, star-based and alphabetical patterns as well. This article will guide you to solve a hut star pattern using nested for loop in Java. Java Program to print Hut Star Pattern Since we are going to solve the problem using nested for loop therefore, it is necessary to discuss its syntax. Syntax for ( initial expression; conditional expression; increment/decrement expression ){ for ( ... Read More

Java has various levels of protection that allow precise control over the accessibility of member variables and methods within classes, subclasses, and packages. The access control mechanism works with the help of access modifiers such as public, protected, private and package. They define scope of a variable, class and method. We are going to understand the various access modifiers in Java. Access Modifiers in Java Public Access Modifier Java does not restrict the accessibility of public members. Anything declared public can be accessible everywhere means we can access them within the class as well as outside the class and ... Read More

The public and protected access modifiers determine how a member of a class or method can be accessed. The modifiers are attached to the members at the time of declaration. We know that these access modifiers play a major role in Java oops concepts like encapsulation, polymorphism and inheritance. It helps in preventing misuse of functionalities provided by a member. We will try to understand public and protected access modifiers in Java through example programs. Access Modifiers in Java Public Access Modifier Java does not restrict the accessibility of public members. Anything declared public can be accessible everywhere means we ... Read More

JSP stands for Java Server Pages and is used for the purpose of developing web based applications. A single JSP page consists of HTML tags for static content and JSP tags to construct dynamic content. The JSP tags start with ‘’. We save our JSP file with the extension ‘.jsp’. Validating a user means simply checking whether the user has entered correct login details or not. The validation process in JSP is quite simple and straightforward. This article will guide you to create a program to validate a user using JSP. Steps to create a Program to Validate a ... Read More
