Constructor in Java: Understanding andImportance
Constructors in Java are special methods that are used to initialize
objects. They are called when an object is created and are used to
set the initial state of the object.
Default Constructor in Java
• A default constructor is a constructor that has no
parameters.
• If a class does not explicitly define any constructor, the
Java compiler automatically provides a default constructor
for that class.
• The default constructor initializes all instance variables to
their default values.
Custom Constructor in Java
• A custom constructor is a constructor that has one or more
parameters.
• A class can have multiple custom constructors, each with a
different number or type of parameters.
• Custom constructors are used to initialize an object with
specific values when it is created.
• Custom constructors are called instead of the default
constructor when an object is created using
the new keyword and the constructor's name.
