What is the output of the following program
public class Test {
private int i = giveMeJ();
private int j = 10;

private int giveMeJ() {
return j;
}

public static void main(String args[]) {
System.out.println((new Test()).i);
}
}
Select one correct answer
OPT:a. Compiler error complaining about access restriction of private variables of AQuestion.
OPT:b. Compiler error complaining about forward referencing.
OPT:c. No Compilation error - The output is 0;
OPT:d. No Compilation error - The output is 10;
ANS:c, I think the answer should be d, but the compiler also supports c, plz help me
Here is a method which creates a number of String objects in the course of printing a count down sequence.
public void countDown() {
for( int i = 10 ; i >= 0 ; i-- ){
String tmp = Integer.toString( i );
System.out.println( tmp );
}
System.out.println("BOOM!");
}
When the program reaches line 6, how many of the String objects created in line 3 are eligible for garbage collection? Assume that the System.out object is not keeping a reference.
OPT:a. none
OPT:b. 1
OPT:c. 10
OPT:d. 11
Hi Thomas Paul
the question says " method which is invoked" , that means user is not invoking it , the method is invoked by the jvm. and I think jvm always call paint() rather than repaint(). repaint() is generally used in user codes
what do u say

if a compiled class is executed with the following option:
java -cs AClass a b c
Which statement is true?

A.args[0]="-cs";
B.args[1]="a b c";
C.args[0]="java";
D.args[0]="a";
E.args[1]='b';
Ans = d
could u people plz explain what is this option, and how is it effecting the result
An AWT GUI under exposure condition,which one or more method will be invok when it redraw?

A.paint();
B.update();
C.repaint();
D.drawing();
Ans = c
well , I think its paint(), could someone plz provide explanation regarding it. thanks in advance
the answer seems to be wrong
if a classes should not be duplicated, ordered, and no special
search facility which of the following will u use.
a.list
b.set
c.map
d.collection
answer = d, but I think it should be b.
list is ordered, rejected
map dont allow duplicates but search is fast, rejected
collection is not a class, rejected
left out is set
Thanks for ur responses friends
Do u think these kinds of certificates would help in getting admissions or scholarships in universities to do Masters in computer science in USA
I would like to know ur comments about this.
hello friends,
sometimes I doubt, whether my choice of giving scjp is correct or not. there r a lot of people with lots of such certificate and still searching for good jobs. then what is the use? ( dont take me wrong please)
well I am not strongly opposing it, but well I am not able to decide how will it help me getting a job. I'm just a fresh computer engineering graduate, and have done a lot of projects in java. will this scjp also help in higher studies in usa.
I would be greatful to u, have any of u also went through the same phase that I am passing, plz help me.
