Hi,
I have passed my SCJP in August ( 19 th ) . I still did not receive my Certifictae from sun .When will i receive it ?

Hi all,
Today i have cleared my scjp exam with 85 % . I would really like to thank javaranch forum and its moderaters for such a wonderful site . This site has contributed much to my success today . Unfortunately i could not get scjp 1.4 K&B book in my place. May be i would have scored much more if i had that book with me . But still i gave it a try through some mock exams..
Thankyou once again one and all..

Hi,
Local variables are always given more preference than global variables . This does'nt mean that the static variable is not visible inside the method . If you remove the local variable, you can get " Am i always visible? " as output.

Thankyou So much shilpa...Thankyou srikanth and wise...i will try my level best

Hi all,
Am going to take scjp 1.4 tomarrow 12.15 EST. I have taken Marcus green tests jiris tests and some other mock tests and scored 85% on an average. I feel i am OK with my preparation.Any suggestions are appreciated...

Because you are throwing an Exception but not handling it properly..

Hi,
Do we need to know about compareTo() and comparator for scjp 1.4 ?

Thankyou for your reply ..i dint notice that

HI,
We know that private methods are not overriden . If we have a method with same name in super class and sub class but declared as private in superclass and public in subclass and if we try to invoke subclass method with a superclass reference, it should give compile error . But the following code is giving me the output:I am saying hello. How is this possible ?
public class Person {
private void say(String s){
System.out.println("I'm saying: " + s);
}
public static void main(String[] args) {
Person p = new Director();
p.say("Hello");
}
}
class Director extends Person {
public void say(String s){
System.out.println("I'm the director");
}
}

Hi,
Where do the reference variables live ? on the stack or on the heap ? I thought they live on heap inside the objects . please clear my doubt

If that is the case then there is a possibility of 1233 answer also..which again makes it unpredictable

Hi,
for the above given question , the answer is given as predictabe and it is 0123..can any one tell me how?

public class Test {

static int i = 0;

public static void main(String[] args) {

Thread t = new Thread(new Runnable(){

public void run(){
for(int j = 0; j < 3; j++)
System.out.println(++i);
}
});

t.start();
System.out.println(i);
}
}

Is the output ( given as 0123) predictable and always the same ? If so how ?

public class Test
{
public static void main(String args[])
{
int i = 1;

switch(i++)
{
case 0:

System.out.print(i + " "); //1
break; //2
System.out.print(i + " "); //3

case 1: //4

System.out.print(i + " ");
default: //5
}
}
}

I dont understand why print statement in case 1 is unreachable ..

Are unicode literals represented in hexadecimal notation?
public class Test
{

public static void main(String args[])
{
System.out.println('\u033');
}

}
Why is the above code giving error ? What is the range of unicode literals ?
