hi
In switch statements,case declarations must be final values.We can only use int,char and short variables in case declarations and they must be declared as final keyword.

eg. if you put only 6 instead of choice>6,it 'll compile.

hi

Here " q" is a final variable and when it is assigned by the value 1,how come it is blank variable.And final variables can't be reassigned as they are final but in 1st constructer i=1 and in second constructer we are assinging i =x(i.e whatever the x value is,may be 2,3,4..)though i=1 already so it is opposing the final's rules.
please explain.
shweta

hi
i just want to know that how many attempts i can give with one vouture?
can anybody tell me the details of this exam?

can you explain autoboxing please,i don't know this concept.
shweta

can you please give me the example where two ref.variables are compared with == operater and giving true value.
shweta

thank you very much for the help.

Thanks Henry
== operater is used for ref. variables and equals() method is used for objects.Right?
But in the given example == is used for objects rather than ref. variables.
ref. variables means whatever is given in front of class name.Right?
eg.
Double d=new Double();

here "d" is ref variable and new Double is actual Object.Right?
so when we use == for objects,it should give a error rather that giving any answer.(please see the first example)Can you explain this?

Hi
I am Shweta.I want to give scjp 1.5 but i don't know the syllabus for this.
Can anybody tell me the correct syllabus.I am already preparing for scjp1.4 so which extra chapters are included in 1.5 version.
thanks in advance.

Thanks for the reply but still there is a query.
In 1st and 2nd example,every thing is same so why it is giving "False"answer?
shweta

: hiii,
i have some doubts abt == n equals method.Here are some examples given below.
i m not able to understand the answers,can anyone help me out..



if( new Boolean("true") == new Boolean("true"))
2: System.out.println("True");
3: else
4: System.out.println("False");

Ans---False




1: Double a = new Double(Double.NaN);
2: Double b = new Double(Double.NaN);
3:
4: if( Double.NaN == Double.NaN )
5: System.out.println("True");
6: else
7: System.out.println("False");
8:
9: if( a.equals(b) )
10: System.out.println("True");
11: else
12: System.out.println("False");


Ans--False
True

it is quite confusing to differentiat between these two operations.
