Abstract: “Pattern” as the
name suggests, means series of events occurring
in a definite order. The patterns can be found
in Java and J2ee technologies also. Many a times,
we find that there is a particular way of tackling
a problem. This way is easy and has been used
many times successfully by a number of people
earlier also. This method becomes a pattern.
Learning the design patterns is a multiple step process:
1. Acceptance
2. Recognition
3. Internalization
Patterns Defined: The patterns can be defined in many ways. You can find the definitions of patterns in many good books.
“Design patterns are recurring solutions to design problems.”
Patterns: According to commonly known practices, there are 23 design patterns in Java. These patterns are grouped under three heads:
1. Creational Patterns
2. Structural Patterns
3. Behavioral Patterns
