Java Constructors (constructors)

A constructor is a block of code that initializes an object immediately after the object is created. The structure of the constructor looks similar to a method.

declaring constructors

The general syntax for a constructor declaration is:

123	<Modifiers> <Constructor Name>(<parameters list>) throws<Exceptions list> {}

The declaration of the constructor begins with a modifier.
The constructor can have its access modifier: public , private , protected or package-level (no modifier).

The constructor name is the same as the name of the class. The constructor name is followed by a pair of parentheses, which may include parameters. Optionally, the right parenthesis can be followed by a keyword followed by throws a comma-delimited list of exceptions.

The following code shows an example of a constructor that declares a class Test . The name of the class and the name of the constructor must match.
