test question

[Patrick Wang]

I have been given a test question as below, I think the answer is 5), but not sure about this. Can somebody shed some light on this?
Thx

public class Foo
{
public void doIt( Field myField )
{
???
}
}
Given the above code, what code do you add to the doIt() method to find out whether myField is static?
Choice 1
if ( myField.isStatic() )
Choice 2
if ( myField.getModifier().isStatic() )
Choice 3
if ( Modifier.isStatic( myField.getModifiers() ) )
Choice 4
if ( myField.getModifiers() == Field.STATIC )
Choice 5
A Field object CANNOT represent a static field.

Only Choice 3 is correst. Go to java.lang.reflect package of javadoc to find out why.

To tell you the truth, I did not know the answer. I just went there and found out the answer. I believe you can do the same.
Thank you for asking this one.

BTW, Choice 5 is definite wrong. Just copied from the same place.

A Field provides information about, and dynamic access to, a single field of a class or an interface. The reflected field may be a class (static) field or an instance field.
