Fundamentals Quiz 2

The quiz below tests your knowledge of the material learnt in Fundamentals - Lesson 3 - Primitive Variables.

Question 1 : Which is a valid declaration of a char type?
- A char type must be initialized as a numeric or a single character enclosed in single quotes.
Question 2 : An int can fit into a short?
- Integer types can fit into larger integer types but not smaller. So an int will not fit into a short.
Question 3 : Pick out the valid identifier?
- Identifiers can only start with a letter, the $ symbol or the _ symbol.
Question 4 : What are the two floating point primitive types?
- The two floating point primitive types are double and float.
Question 5 : Will the following code compile?

short s 65; byte b= 65; int i = s + b;
- Variable i is dynamically initialized at runtime from s and b so is fine.
Question 6 : What other integer types can a short fit into?
- A short can fit into an int and a long
Question 7 : What happens when we compile the following statement?

float f = 16.54;
- Doesn't compile as the compiler thinks we are passing a double to a float.
Question 8 : We can use numerics in any position of an identifier?
- You can't start an identifer with a numeric.
