Dan's Question

[Ashok Paulraj]

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);
}}
Is the last print stmt. TRUE ?, can someone explain me.....

Taurean,
LinkedHashMap does not implement the Collection interface
as the answer to the question says.
LinkedHashMap is a subclass of HashMap (which is a
subclass of AbstractMap, that implements the Map
interface which does NOT extend the Collection class)
Therefore System.out.print(m instanceof HashMap);
evaluates to true.
