Hi all,
Finally cleared of the exam with 66% marks not a great score but am happy with it.. coz am a Chemical Engr with no back ground in computers and just startred off in computers in October to learn java and Oracle after quitting my job.
The questions r really great not much of beating around the bush they r fairly straight and excellent i got poor marks in awt package ,garbage collection, java lang & util otherwise it was quite distributed.
Gotta search out for a job and hope to get one soon!!!
Thanks a lot to the members at javaranch and to Maha whose discussions on threads helped me a lot..

class Super {
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) {
Super s = new Sub();
System.out.println(s.greeting() + ", " + s.name());
}
}
Hi aru,
Thanks for it..
But a small doubt would the usage of j before intialisation flag off an error.

public class bb
{
int i = amethod();
int j=10 ;
private bb()
{ int i=100; }
public int amethod()
{
i=j;
System.out.println("inside method " + i + j);
return j;
}
public static void main(String args[])
{
bb b=new bb();
int c = b.amethod();
System.out.println(c);
System.out.println( b.i);
}
}

Hi all,
Please explain this output from this program.

public class bb
{
int i = amethod();
int j=10 ;
private bb()
{ int i=100; }
public int amethod()
{
i=j;
System.out.println("inside method I " + i + j);
System.out.println("inside method II " + i + j);
return j;
}
public static void main(String args[])
{
bb b=new bb();
int c = b.amethod();
System.out.println(c);
System.out.println( b.i);
}
}

I go for C,E.
C is done by giving a call the protected void finalize() throws Throwable method of the Object.
E is true coz gc is a low priority thread.

Hi all,
Please help me with this problem..The output is 22..Please explain !!

class Base {
int i;
Base() {
add(1);
}
void add(int v) {
i += v;
}
void print() {
System.out.println(i);
}
}
class Extension extends Base {
Extension() {
add(2);
}
void add(int v) {
i += v*2;
}
}
public class TestThread3 {
public static void main(String args[]) {
bogo(new Extension());
}
static void bogo(Base b) {
b.add(8);
b.print();
}
}
Its coz the instance variable makes it presence felt inside method blocks or blocks only else if its used directly the compiler flags off an error.

class outer{
int y = 5;
class Inner {
int p;
{p=y;} // now its OK I
public void test(){
p = y; // works fine why ??? why and how ??? II
System.out.println(p);
}
}
}
Its quite simple in the while loop & do-while loop the checking(boolean condition) is checked first and then the increment is done.
Whereas in a for loop the increment is done first and then the condition is checked.
