  hi every expected java programmer
  
  
  whish u all the best
  
  
  i cleared the exam on 06-08-01 with grade 77%
  
  
  i am also mcse. but this exam is not like a microsoft exam. its too much tough than that.following are the steps which help me passing the exam.
  
  
  
  
  firt of all i study the "complete reference" not all chapter just related chapter. then i study "the complete java 2 certification study guide" by simmon robert and "a programmers guide to java certification" by khalid mughal.
  
  
  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#1-which are the reserved words in java(choose two).
  
  
  ans. 1-implements, 2-default
  
  
  
  
  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 ioexception");
  
  
  }catch(exception e){
  
  
  system.out.println("caught exception");
  
  
  }
  
  
  }
  
  
  public void methoda(){
  
  
  throw new ioexception();
  
  
  }
  
  
  }
  
  
  
  
  ans-compilation error
  
  
  
  
  q#6 type in
  
  
  system.out.println(6^3);
  
  
  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
  
  
  string s = new string("xyz");
  
  
  stringbuffer sb = new stringbuffer("abc");
  
  
  s = s.substring(2);
  
  
  system.out.println(s+sb);
  
  
  i am not sure about this question.
  
  
  
  
  q#9 what collection used when uniqueness rquired and retrieve in natural order
  
  
  1-set
  
  
  2-sortedset
  
  
  3-map
  
  
  4-collection
  
  
  ans- i choose sortedset.
  
  
  
  
  q#10 what will be output when compile the following code
  
  
  public class x implements runnable{
  
  
  private int x;
  
  
  private int y;

  x that = new x();
  
  
  (new thread(that)).start();
  
  
  (new thread(that)).start();
  
  
  }

  for( ; ; ){
  
  
  x++;
  
  
  y++;
  
  
  system.out.println("x=" + x + ", y=" +y);
  
  
  
  
  ans-value of x and y will be same on same and appears onece and will not twice
