Character class in Java (Part 1)

The Character Class: (Part 1)

  • A character data type represents a single character.
  • The character data type, char, is used to represent a single character. A character literal is enclosed in single quotation marks.
  • For example: (char literals)

    char letter = 'A';
    char numChar = '4';

    Here, the first statement assigns character A to the char variable letter. The second statement assigns digit character 4 to the char variable numChar.
  • NOTE: A string literal must be enclosed in quotation marks (" "). A character literal is a single character enclosed in single quotation marks (' '). Therefore, "A" is a string, but 'A' is a character.
  • Also, a string is a combination of one or more characters. We can also see Strings as "A Sequence of Characters".
  • Every key on the keyboard has a specific integer value. It is known as the ASCII code. See HERE for more information.

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 ...
