I'm constructing a hashtable as follows:

code:
Hashtable <String, Proc> procedures = new Hashtable();


It warns me:
code:
parser.java:360: warning: [unchecked] unchecked conversion
found   : java.util.Hashtable
required: java.util.Hashtable<java.lang.String,CUP$parser$actions.Proc>
Hashtable <String, Proc> functions = new Hashtable();
                                     ^
1 warning


Help please. Smile

by assigning it
Java:
new Hashtable();
you are infact assigning it
Java:
new Hashtable<Object, Object>();
instead, it should be more specific:
Java:
new Hashtable<String, Proc>();
