Objects and Collections

[sri rallapalli]

in K&B book,
page no:18, of Objects and Collections chapter, figure says that LinkedHashMap is not an instance of HashMap.
But in the following example, it is showing that LinkedHashMap is an instance of HashMap.

import java.util.*;
class GFC111 {
public static void main (String[] args) {
Object m = new LinkedHashMap();
System.out.print((m instanceof Collection)+",");
System.out.print((m instanceof Map)+",");
System.out.print(m instanceof HashMap);
}}
Please Calrify my Doubt. I want to know whether the figure in K&B book is wrong or correct.
thanks,
Sri.

According to the Javadoc, the LinkedHashMap class does indeed inherit from the HashMap class.

Just finishing up the errata list - so far 5 confirmed errata, and about 5 good suggestions...

public class LinkedHashMap extends HashMap implements Map
