  {

  System.out.println("Inside throwMethod.");

  throw new IllegalAccessException("demo");

  }

  public static void main(String args[])

  {

  }

  }

  }

  Choices:

  A.Compilation error

  B.Runtime error

  C.Compile successfully, nothing is printed.

  D.Inside throwMethod. followed by caught:java.lang.IllegalAccessExcption: demo

  8:假定a和b為int型變量,則執(zhí)行下述語句組后,b的值為

  a=1;

  b=10;

  do

  {

  b-=a;

  a++;

  } while (b--<0);

  A.9

  B.-2

  C.-1

  D.8

  9:

  public class X{

  public Object m(){

  Object o = new Float(3.14F);//line 3

  Object [] oa = new Object;//line 4

  oa[0] = o;//line 5

  o=null;//line 6

  return oa[0];//line 7

  }

  }

  When is the Float object, created in line 3,eligible for garbage collection?

  public class X{

  public Object m(){

  Object o = new Float(3.14F);//line 3

  Object [] oa = new Object;//line 4

  oa[0] = o;//line 5

  o=null;//line 6

  return oa[0];//line 7

  }

  }

  When is the Float object, created in line 3,eligible for garbage collection?

  A.just after line 5.

  B.just after line 6

  C.just after line 7(that is,as the method returns)

  D.never in this method

  10:Math.round(-11.5)等於多少?

  A.-11

  B.-12

  C.-11.5

  D.none

  11:In the following pieces of code, which one will compile without any error?

  A.StringBuffer sb1 = "abcd";

  B.Boolean b = new Boolean("abcd");

  C.C: byte b = 255;

  D.float fl = 1.2;

  12:

  Give the following method:

  public void method( ){

  String a,b;

  a=new String(“hello world”);

  b=new String(“game over”);

  System.out.println(a+b+”ok”);

  a=null;

  a=b;

  System.out.println(a);

  }

  In the absence of compiler optimization, which is the earliest point the object a refered is definitely elibile to be garbage collection.

  Give the following method:

  public void method( ){

  String a,b;

  a=new String(“hello world”);

  b=new String(“game over”);

  System.out.println(a+b+”ok”);

  a=null;

  a=b;

  System.out.println(a);

  }

  In the absence of compiler optimization, which is the earliest point the object a refered is definitely elibile to be garbage collection.

  A.before line 5

  B.before line 6

  C.before line 7

  D.before line 9

  13:

  Give the following java class:

  public class Example{

  static int x[]=new int[15];

  public static void main(String args[]){

  System.out.println(x[5]);

  }

  }

  Which statement is corrected?

  Give the following java class:

  public class Example{
