Fundamentals Quiz 5
The quiz below tests your knowledge of the material learnt in Fundamentals - Lesson 6 - Method Scope.
Question 1 : What are variables created within method scope known as?
- Variables created within method scope known are known as local variables.
Question 2 : Parameters passed to a method are within method scope?
- Parameters passed to a method are included as part of the method scope.
Question 3 : What is wrong with the following snippet of code?
public static void main (String[] args) {
float aFloat = 12.34F;
double aDouble;
double bDouble = aFloat * aDouble; }
- Variable aDouble is not initialized (variable bDouble is dynamically initialized at runtime).
Question 4 : What is the lifetime of a local variable?

Question 7 : Is the following snippet of code valid?
public static void main (String[] args) {
int a = 0;
while (a < 2) { int a = 0; a++; } }
- Variables declared in an inner scope cannot have the same name as variables declared in an outer scope.
