Hello Mukti you are right
Javadoc is common javatool like as javac,java . It generates java documents in HTML format. I mean API in HTML form.There are many options keys which do various function along with javadoc.
So go to API and see ,in what color the class methods are. It is blue.

Q6) Which of the following integer primitive can correctly represent a value of 65535?
Answer given : a,d.
An int and a long variables each being represented by 32 bits and 64 bits respectively can each store the value 65535. in short( 16 bits )the first bit represents the sign bit hence we cannot store this val in a short variable. But I am doubtful about the answer b in fact a char being a 16 bit val it must represent this
val 65535. Any body help me in thie regard
Answer.
Only int & long can hold 65535. short can't hold as it is 16 bit and its range is between -32768 to 32767.
And when it comes to char type it can hold values only in "unicode character format".That means it hold characters in the range from \u0000 to \uffff. Then How come the number 65535 fits in it.It doesn't .( Moreover a char's size is 16 bit )

Q11)Anonymous arrays can be created.
a] True
b] False
I guess it is false
Can some one give more explanation
Answer
yes.Anonymous Arrays can be created . The reason being Arrays are composite Datatype holders like classes. & unlike conventional dataholders/datatypes (int,long,float,boolean etc...).
We can put any type of information like as Unicode characters,integer(signed),ieee754 & boolean one's in to an array,In which various data type initialze to their default values.0 in the case of int,\u0000 for chars,false for boolean.
So with out certainity,they can be created
My answer is arrays can be anonymous.Suggestions accepted.
