hii i have two queries...

1. The cd i got with K&B has learnkey 3 exam 2 mock exam and 1 master exam
pls tell me what the average score one must score to have good confidence in them..............when people say i.e above 90% are they talking of all the average of 3 or only master exam ?


2 in one of the question of mock exam

public class Test{
public static void main(String args[])
long [] [] a1;
long [] a2[];
a2=new long[3][];
a1=a2;
System.out.println(a1[1][0]);
}}

the answer is compiler errror ? why ?

i think it should be runtime error... i.e NullPointerException error ?

pls confirm

how much condifence a person has on something is really depend on him/her self, and it really varies for each individuals, it shows you don't have confidence when you ask confidence related questions




2 in one of the question of mock exam

public class Test{
public static void main(String args[])
long [] [] a1;
long [] a2[];
a2=new long[3][];
a1=a2;
System.out.println(a1[1][0]);

if you did not miss copying this code, then you should look at how many open and closing brackets it has

why do ppl give mock exam ...just to get confidence regarding the exam ..and to learn new things...

if you ask others ...all will say that getting good marks in some mock exam will definetly increase their confidence in sitting in exam...
.......if you don't wana reply to the point better not answer adversly..



hope you understand...

amit

Only problem is the the main class with out the bracket '{'

If that condition is fulfilled then, it is compiles fine and throwing NullPointException
