1.1: Overview of Java Programming in simple words

Java programming is a popular programming language used to develop software applications for various platforms. Java is known for its "write once, run anywhere" feature, which means that once a Java program is written, it can be run on any platform without the need for modification. Java is also an object-oriented programming language, which means it is based on the concept of objects and classes that can be used to create complex and scalable applications. In simple words, Java programming involves writing code using the Java programming language to create software applications for desktop, mobile, and web platforms.

// Class declaration
public class MyClass {

  // Main method declaration
  public static void main(String[] args) {
