JVM - Advantages

>

Advantages of Java Virtual Machine:

Java is the first truly portable language. This is because of JVM architecture which offers several advantages such as: cross-platform portability and security.
  1. Cross platform portability: The JVM provides cross-platform portability. The programs are written for the JVM, not for the operating system (OS). Because all JVMs look the same to Java programs, you have to write only one version of your program, and it will work on all JVMs. The JVM interprets the byte-code and carries out the program's operations in a way that is compatible with the current hardware architecture and operating system.
  2. Security: Java has been designed to protect users from malicious programs. Programs from an untrusted source (for example, the Internet) execute in a restricted environment (known as a sandbox). The JVM can then prevent those programs from causing mischief. For example, a Java applet (a small program that runs on a Web page) usually can't access local files or open network connections to arbitrary computers. These restrictions prevent a Web page from erasing your critical files or sending threatening email from your computer.
And many more ofcourse.. We will discover them while we are in the flow of learning process.

ASCII Code in Java (Part 1)

> The ASCII Code: (Part 1) ASCII stands for "American Standard Code for Information Interchange". As you may remember (Grade 9), computers only work with HIGH(1) and LOW(0) electrical states, known as bits, with correspond to mathematical Base 2 numbers. That is, computers only understand binary language. ASCII codes represent text (or other things) in computers. Assume that you are working with MS Word, or PPT or any other tool that uses text based inputs from user. You need to type a sentence that computer is not aware of. ASCII codes help to exchange this information between user and computer. When you type a character, it is converted into ASCII code first and then into Binary, which makes the computer understand what is to be typed. Hence every key on the keyboard has a specific ASCII code which is used to make the computer understand our language. If you press 4 from keyboard, then keyboard send the value 100 (value equival...

Characteristics of Java OR Java Buzzwords (Part 2)

> Java Properties: (Part 2) Robust: Java is robust because it is more reliable. It ensures the reliability by providing early checking for possible errors. It eliminates error causing constructs such as pointers. Java restricts the programmers in a few key areas, to force them to find mistakes early in program development. At the same time, Java frees from having to worry about many of the most common causes of programming errors. Because Java is a strictly typed language, it checks the code at compile time. However, it also checks your code at run time. Consider two main reasons of program failure: Memory management mistakes and Mishandled exceptional conditions (run time errors). Memory management is difficult and tedious in c/c++, the programmers have to manually allocate and free memory. This sometimes leads to problems, because programmers will either forget to free memory that has been previously allocated or, worse, try to ...
