A DESCRIPTION OF THE REQUEST :
It is a little unwieldy to have to call new LinkedHashMap(16, 0.75f, access_order) in order to set the access order.  Most developers don't care about the initial capacity or load factor and want to use the defaults.

JUSTIFICATION :
Developers don't have to go to the javadoc to figure out what reasonable defaults are.


---------- BEGIN SOURCE ----------
public class LRUMap<K,V> extends java.util.LinkedHashMap {

    int maxsize = 60;
    /** Creates a new <code>LRUMap</code> instance.
     * @param access_order if false then order is strictly by insertion
     * order, <code>get()</code> calls don't change anything */
    public LRUMap(boolean access_order, int maxsize) {
        //defaults taken from source for HashMap
        super(16, 0.75f, access_order);  //<-- messy code
        this.maxsize = maxsize;
    }
    protected boolean removeEldestEntry(Map.Entry<K,V> eldest){
        return size() > maxsize;
    }
}

N/A

Java does not have keyword parameters; would be nice.
We have these "telescoping constructor" issues in other classes as well.
