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
