How to Learn Java in Simple Way?

Java is concurrent, class-based, object-oriented and specifically designed to have as few implementation dependencies as possible. Java technology is used to develop applications for a wide range of environments, from consumer devices to heterogeneous enterprise systems. In this section, get a high-level view of the Java platform and its components.

You can learn Java in simple way with basic Introduction to Java, Object Oriented Programming, Data types and Variables, Modifier Types, Operators, Loop controls, Decision Making, Arrays and String, Methods, Inheritance, Interface, Package, Polymorphism, Overriding, Encapsulation, Abstraction, Exception, Inner class, File etc.

No matter what you write in the documentation section, the Java compiler will ignore that statement during program execution. Use comments to write statements in the documentation area. Comments can be single-line comments, multi-line comments, and documentation comments.

In the Java programming language package part is always optional. It is placed immediately after the documentation section. This section declares the package name where the class is located. Note that there can be only one package statement in your Java program. Must be defined before all class and interface declarations.

The package part consists only of predefined classes and interfaces. If you want to use a class from a particular package, you have to import that class. An import statement represents a class stored in another package, and the import keyword is used to import the class. Use the import declaration in ways. Import a specific class or import all classes in a specific package. A Java program can have multiple import statements.

A class is a blueprint for a Java program that mainly contains information about user-defined methods, variables, constants etc.. Every Java program has at least one class with a main() method.

A Java program can associate multiple class definitions. Using the class keyword, a class can be defined. A class is a blueprint for a Java program.

Mainly it contains information about user-defined methods, variables, constants etc. Every Java program has at least one class with a main() method.

Variables and constants are used to store parameter values during program execution. You can also use modifiers to scope and define the lifetime of the variable.

You can define the main() method in a Java program. This is essential for all Java programs. Because all Java program execution begins with the main() method always.

Java applications are purely Enterprise based applications and are related to middleware applications. All companies use technology and services to enable their software applications and hardware systems. Therefore, we call it an enterprise application. Enterprise applications are designed primarily for enterprise sites such as banking systems.
