    About this ebook

    Java serves as both a programming language and a platform. It is a sophisticated, secure, and object-oriented programming language. Sun Microsystems (now a subsidiary of Oracle) developed Java in 1995, and its conception is credited to James Gosling, often referred to as the father of Java. Originally named Oak, the language underwent a name change to Java when it was discovered that the name Oak was already claimed by another company. Regarding its platform designation, Java qualifies as such because it can operate within various hardware or software environments. This is due to its inclusion of a runtime environment (JRE) and API, which enables it to function as a self-sustained platform for running applications.

    Please read this carefully and hopefully you will find it helpful. This book has been written with advise of multiple experts who have command over JAVA programming. They have couple of years experiance in JAVA. Please reach out to email [email protected] for any suggestion, query or questions. Thank you.

      Java Programming

      Java serves as both a programming language and a platform. It is a sophisticated, secure, and object-oriented programming language. Sun Microsystems (now a subsidiary of Oracle) developed Java in 1995, and its conception is credited to James Gosling, often referred to as the father of Java. Originally named Oak, the language underwent a name change to Java when it was discovered that the name Oak was already claimed by another company. Regarding its platform designation, Java qualifies as such because it can operate within various hardware or software environments. This is due to its inclusion of a runtime environment (JRE) and API, which enables it to function as a self-sustained platform for running applications.

      In Java, the main method serves as the entry point of the program and is executed when the program runs.

      Here's a brief explanation of the code:

      class Simple {

      public static void main(String args[]) {

      System.out.println(Hello Java);

      }

      }

      class Simple: This line begins the definition of the class named Simple.

      public static void main(String args[]): This line defines the main method, which is declared as public, meaning it can be accessed from outside the class. The keyword static
