Runnable r = new Runnable()
{
public void run()
{
System.out.print("Cat");
}
};
Thread t = new Thread(r)
{
public void run()
{
System.out.print("Dog");
}
};
t.start();
What is the result?
A Cat
B Dog
C Compilation fails.
D The code runs with no output.
E An exception is thrown at runtime.

public class TestOne implements Runnable
{
public static void main (String[] args) throws Exception
{
Thread t = new Thread(new TestOne());
t.start();
System.out.print("Started");
t.join();
System.out.print("Complete");
}
public void run()
{
for (int i = 0; i < 4; i++)
{
System.out.print(i);
}
}
}
What can be a result?
A Compilation fails.
B An exception is thrown at runtime.
C The code executes and prints "StartedComplete".
D The code executes and prints "StartedComplete0123".
E The code executes and prints "Started0123Complete".

public class Drink implements Comparable
{
public String name;
public int compareTo(Object o)
{
return 0;
}
}
and:
Drink one = new Drink();
Drink two = new Drink();
one.name= "Coffee";
two.name= "Tea";
TreeSet set = new TreeSet();
set.add(one);
set.add(two);
A programmer iterates over the TreeSet and prints the name of each Drink object. What is the result?
A Tea
B Coffee
C Coffee Tea
D Compilation fails
E The code runs with no output.

int[] myArray = new int[] {1, 2, 3, 4, 5};
What allows you to create a list from this array?
A List myList = myArray.asList();
B List myList = Arrays.asList(myArray);
C List myList = new ArrayList(myArray);
D List myList = Collections.fromArray(myArray);

public class Score implements Comparable
{
private int wins, losses;
public Score(int w, int 1)
{ wins = w; losses = 1; }
public int getWins()
{ return wins; }
public int getLosses()
{ return losses; }
public String toString()
{
return “”;
}
// insert code here
}
Which method will complete this class?
A public int compareTo(Object o) {/*mode code here*/}
B public int compareTo(Score other) {/*more code here*/}
C public int compare(Score s1,Score s2){/*more code here*/}
D public int compare(Object o1,Object o2){/*more code here*/}

A programmer has an algorithm that requires a java.util.List that provides an efficient implementation of add(0, object), but does NOT need to support quick random access.
What supports these requirements?
A java.util.Queue
B java.util.ArrayList
C java.util.LinearList
D java.util.LinkedList
E none

public static Iterator reverse(List list)
{
Collections.reverse(list);
return list.iterator();
}
public static void main(String[] args)
{
List list = new ArrayList();
list.add("1"); list.add("2"); list.add("3");
for (Object obj: reverse(list))
System.out.print(obj + ", ");
}
What is the result?
A 3, 2, 1,
B 1, 2, 3,
C Compilation fails.
D The code runs with no output.
E An exception is thrown at runtime.

import java.util.*;
public class Example
{
public static void main(String[] args)
{
// insert code here
set.add(new Integer(2));
set.add(new Integer(1));
System.out.println(set);
}
}
Which code, inserted at line 4, guarantees that this program will output [1, 2]?
A Set set = new TreeSet();
B Set set = new HashSet();
C Set set = new SortedSet();
D List set = new SortedList();
E Set set = new LinkedHashSet();

Given classes defined in two different files:
package util;
public class BitUtils
{
public static void process(byte[])
{
/* more code here */
}
}

package app;
public class SomeApp
{
public static void main(String[] args)
{
byte[] bytes = new byte[256];
// insert code here
}
}
What is required at line 5 in class SomeApp to use the process method of BitUtils?
A process(bytes);
B BitUtils.process(bytes);
C util.BitUtils.process(bytes);
D SomeApp cannot use methods in BitUtils.
E import util.BitUtils.*; process(bytes);

public class Yippee2
{
static public void main(String [] yahoo)
{
for(int x = 1; x < yahoo.length; x++)
{
System.out.print(yahoo[x] + " ");
}
}
}
and the command line invocation:
java Yippee2 a b c.

What is the result?
A a b
B b c
C a b c
D Compilation fails.
E E. An exception is thrown at runtime
