How can I pass mock exams ??
Please Suggest ...

No. But there were many questions regarding abstract classes.. If you have your basic concepts right, you can still pass the exam. I faltered in those questions in which you hae to do lot of mugging up. I think the best mock exams are of Marcus Green's, Majji's, Jaworoski's and RHE's.
Marcus Green is easier than the real exam by about 5%
Majji is nearly same as the real exam.
Jaworoski is also nearly same as the real exam.
RHE is easier than the real exam by about 7-8%
Though khalid also is very good, but I would not suggest you give it as it is very tough, can say nearly 25-30% as the real exam. If you get a low score, one may get a negative feeling. I got only 54% in Khalid's Exam.

P.S. when ever you give mock exams, do a lot many together in cycles and never write or mark answers on the question sheet. By doing this you will not remember answers to the questions.

hello everyone,
Today I cleared my SCJP exm with 72%. I lost a lot in file and util packages and also in garbage collection. Anyway thanks to Javaranch and all its contributers.

class InOut{
String s;
public void amethod(final int iArgs){
int iam;
class Bicycle{
public void sayHello(){
System.out.println(s);
}
}
}
public void another(){
int iOther;
}
}
The above code compiles well. But in some books it is written that only final variables be accessible to local inner classes.

Q1. 4 objects are being created from two string literals. if i am wrong, then only 2 objects are being created. But 3 should not be the answer in any case.
Q2. A and C are correct. this() or super() have to be the first statement in the constructor.
Q3. Exception would be thrown only when you create an existing reference i.e. Object a;Object a;. But when a reference is created, it can be assigned to any object at any time.

strictfp is a keyword but only for Java 2.
follow the above link.
hence if you have jdk 1.2/1.3 installed int strictfp; should not compile
K Singh

inner class should be compared to a method.
as a method cannot contatin static variable, inner classes can
also not contain any static classes,methods and variables
K Singh

class upper{
void ft(){
System.out.println("upper ft");
}
void gt(){
System.out.println("upper gt");
}
}
class lower extends upper{
void ft(){
System.out.println("lower ft");
}
public static void main(String args[]){
upper c=new lower();
((upper)c).ft();
((upper)c).gt();
}
}
output is is
lower ft
upper gt

regarding Q1
i++ returns i, but increases the value of i by 1
K Singh

it proves constructor are not inherited
K Singh

how good is 55% in Khalid's exam?
K Singh

I don't thing yield() is the correct answer. It only puts the thread to ready state but not stop it.

b also compiles

What happens when you compare different primitive types other than int?
e.g.:
int i=123;
char c='1';
float f=1.0f;
if (f==c)
{ System.out.println("float 1= char 1);
}
if (123*f==i)
{stuff here
}
}

its b'coz char c='1' is not 1 but 49 (ascii value). If you put char c=1 or char c='ctrl+a', the the answer will be true.

I think the static methods called on the object are in the class to which it belongs, not where it is referenced
e.g.
class duper{
static String greeting() { return "Super duper"; }
String name() { return "Anna"; }
}
class Super extends duper{
static String greeting() { return "Goodnight"; }
String name() { return "Richard"; }
}
class Sub extends Super {
static String greeting() { return "Hello"; }
String name() { return "Dick"; }
}
class statictest {
public static void main(String[] args) {
duper s = new Sub();
System.out.println(s.greeting() + ", " + s.name());
}
}
this code would print Super duper, Dick
K Singh

yes you can have.
