In this example, the class Rectangle contains a parameterized constructor. The specified values passed to this constructor are used to initialize instance variableslengthand breadth of an object. On the execution of the statement, Rectangle firstRect= new Rectangle (5, 6); the arguments 5 and 6 ...
While discussingdefault constructor, we have seen that when we do not create a default constructor, Java compiler inserts the default constructor into the code on our behalf. However this is not always true. See the example below: classExample{Example(inti,intj){System.out.print("parameterized c...
