-
Suppose that you would like to create an instance of a new Map that has an iteration order that is the same as the iteration order of an existing instance of a Map. Which concrete implementation of the Map interface should be used for the new instance?
-
Which class does not override the equals() and hashCode() methods, inheriting them directly from class Object?
-
Which collection class allows you to grow or shrink its size and provides indexed access to its elements, but whose methods are not synchronized?
-
You need to store elements in a collection that guarantees that no duplicates are stored and all elements can be accessed in natural order. Which interface provides that capability?
-
Which interface does java.util.Hashtable implement?
-
Which interface provides the capability to store objects using a key-value pair?
-
Which collection class allows you to associate its elements with key values, and allows you to retrieve objects in FIFO (first-in, first-out) sequence?
-
Which collection class allows you to access its elements by associating a key with an element's value, and provides synchronization?
-
Which is valid declaration of a float?
-
/* Missing Statement ? */ public class foo { public static void main(String[]args)throws Exception { java.io.PrintWriter out = new java.io.PrintWriter(); new java.io.OutputStreamWriter(System.out,true); out.println("Hello"); } }What line of code should replace the missing statement to make this program compile?
