Charset and Encodings

Charset is a combination of a coded character set and a character-encoding scheme. Here ‘set’ refers to the set of characters and their numbers (code points), and ‘encoding’ refers to the representation of these code points. We will also discuss common encoding related errors.

Unicode Escapes In Java

All Unicode characters can be used in comments, character and string literals in java. Unicode characters can be expressed through Unicode Escape Sequences. 

Unicode escape sequences consist of

What is Unicode?

Unicode is a computing industry standard for the consistent encoding, representation and handling of text expressed in most of the world's writing systems. The objective of Unicode is to unify all the different encoding schemes so that the confusion between computers can be limited as much as possible. Currently the Unicode standard defines values for over 100,000 characters.

Escape Sequences in Java with Examples

Escape characters (also called escape sequences or escape codes) in general are used to signal an alternative interpretation of a series of characters. In Java, a character preceded by a backslash (\) is an escape sequence and has special meaning to the java compiler. 

StringBuffer and StringBuilder

Strings are immutable and a new String object is created every time you modify a Sring object. A StringBuffer is a thread-safe, mutable sequence of characters. A StringBuilder is similar to StringBuffer, but with no guarantee of synchronization.
