At last i done different Mock exams like Morcus greens three exams and khalid mughals mock exams and four days before exam i study the sasasite.com questions
following are the question of exam which are right now in my memory.
Prerequist: Determination and hardworking

Q#2-out put of the following code on execution
int i = 1;
while(i){
do some thing

Ans. code will not compile
Q#3- when the object created at line 3 will elligible garbage collected.
1-public class foo{
2-public object m(){
3-Object o=new Float(2.14F);
4-Object [] oa=new Object[1];
5-oa[0]=o;
6-o=null;
7-return o;
}
}
I choose after line 6 which was wrong.
Q#4-almost four question on overriding overloading which was very simple.
Q#5-out put when execute the following code
public static void main(String arg[]){
try{
methodA();
}catch(IOException io){

System.out.println("caught Exception");
}
}
public void methodA(){
throw new IOException();
}
}
Ans-compilation error
Q#6 Type in

Ans-5
Q#7 which give output "true" (choose two)
Integer i = new Integer(5);
Double d = new Double(5);
Long l = new Long(5);
option given was
1-System.out.println(i==d);
2-System.out.println(d==l);
3-System.out.println(i.equal(d));
4-System.out.println(i.equal(l));
5-System.out.println(d.equal(l));
i think all give "false" output ,all wording is same as i write
i can not understand how he is aSKINg about true, because no one giving true output.
Q#8 Type in, what was the result when the following code compile
