why the constructor should be used in class,if there is no
constructor what will happen?
Answers were Sorted based on User's Feedback
In Java, initialization of every object possible
by providing a constructor. If a class has a constructor,
Java automatically calls that constructor when an object is
created. So initialization is guaranteed.
If we don't define a constructor for a class, a default
parameterless constructor is automatically created by the
compiler.
