Which of the following statements is false?
a. because a wildcard is a type-parameter name, you can use it as a type name throughout a method's body.
b. a wildcard-type argument is denoted by ? ,
c. which represents an "unknown type." if a wildcard is specified without an upper bound, then only the methods of type object can be invoked on values of the wildcard type.
d. wildcard type arguments enable you to specify method parameters, return values, variables, and so on, that act as supertypes of parameterized types.

The correct option to the following question is A.).

Explanation:

The following statement is false because,

We cannot use as the type-name throughout the function's body. That's why the Wildcard type argument is referred to as the unknown types arguments and it acts as the placeholders for a real argument that are pass during the calling of the function. A wildcard arguments are denoted by the Question mark(?).

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
