      Type conversion is required mainly in user input. When the user input is not in a accepted form to your program, then type conversion is required. For example, when you ask the user to enter cost of mangoes in double form; but the user entered in integer form as 15 instead of 15.0, here conversion is required. For further see way2java link:

      To my knowledge Java is Object oriented but not Pure.
      As in Java the primitive data types are not of type Object. Rather you can convert them through wrapper class.
      And the second thought comes to my mind about why java is not pure OO.

      Through interface you can implement multiple inheritance but the methods are abstract… So you have to define them where you use them.

      For eg. In real life inheritance is like you get your nose for your Mom Dad… But in java you get a node but you have to define it bu yourself…

      Hope i am able to make myself clear… :)

        Do not worry much about Java is OOPs language or not.

        Primitive date types are given to make programming easy. No primitive data types are there, you must your self boxing operations for every data type. Infact, all DS of Java store primitive data types as objects.

        Multiple inheritance is basically avoided to come out of the problem of virtual functions.
