Question

I expect the answer is F but I am a little confused. Do you mind explaining your reasoning?

T/F Calling a void method can be part of an expression.

I believe the following is T, am I right?

A variable declared within the body of a loop does not retain its value from one loop iteration to the next.

I believe the following is T, am I right?

Named method parameters are stored in a call frame on the stack.

I believe the following is T, am I right?

A block of statements may be used anywhere a single statement is expected.

I believe the following is F, am I right?

Getters that comply with the JavaBeans convention are always declared with a void return type.

I believe the following is F, am I right?

A statement can be used wherever an expression is expected.

I believe it is T, am I right?

Every object is associated with a specific class used to create that object.

Answer 1

1. Calling a void method can be part of an expression. False
   Explanation: An expression is always used to calculate some value, so if an expression contain void method(), it means method do not return any value. That's why a void method can't be part of an expression.
2. A variable declared within the body of a loop does not retain its value from one loop iteration to the next. False
   Explanation: It is false, Generaly a local variable change their value from one loop iteration to the next but it is not always true, suppose we have a string variable declared within loop is intitialized with "Welcome" and we use it to display this message on each loop iteration so it retain its value.
3. Named method parameters are stored in a call frame on the stack. True
   Explanation: Each time a method calls another method, an entry is pushed onto the stack and this entry is called a stack frame or an activation record. A stack frame contains the return address that the called method needs in order to return to the calling method.
4. A block of statements may be used anywhere a single statement is expected. True
   Explanation: A statement is a command executed by translator program (compiler etc.). It could be either single statement or compound statement. We can use a compound statement when a single statement is required.
5. Getters that comply with the JavaBeans convention are always declared with a void return type. False
   Explanation: A getter method has no parameters but returns a value of the property's type. It is used to returns its value. Therefore, we never used a void as a return type for getter method.
6. A statement can be used wherever an expression is expected. False.
   Explanation: We cannot write a statement where expects an expression. For example, an if statement cannot become the argument of a function.”
7. Every object is associated with a specific class used to create that object. True
   Explanation: An object is created from a class. An instance is a specific object created from a particular class. Therfore, every object is associated with a specific class used to create that object.
