will we loose precision by implicit conversion

Question

There is a question in Java past exam paper that brothers me:

With implicit conversion of primitive data types, you can lose precision and get incorrect results.

A True, B False

The key to the answer is A: True

I think it will neither lose precision nor get incorrect results. I know the explicit conversion can lose precision and get incorrect results but not implicit one.

For example:

int i = 9;

short s = 3;

i = s; // implicit conversion, neither loose 
      //precision nor incorrect results

s = i; // compile error, do we call this implicit conversion? 
       //if yes, then the answer to question 3 is True, 
       //but I don't think this is an implicit conversion, 
       //so I think answer is false.   

As states on the notes:

Implicit type conversion: The programmer does not make any attempt to convert the type, rather the type is automatically converted by the system under certain circumstances.

Could anyone please advise?

Many thanks.

Answer 1

Answer = A

    float f = Long.MAX_VALUE;
    System.out.println(Long.MAX_VALUE);
    System.out.printf("%.0f", f);
