To get char value stored in Character object, use, charValue() method.

eg.;  Character chObj = new Character('a');
      char c = chObj.charValue();
      System.out.println("character:" + c);

To compare both, use something like,
if (chObj.charValue() == 'a') System.out.println("equal");

//where stack is your Stack object
myChar char = "a";
for (int i = 0; i < stack.size(); i++){
    if (((Character)stack.elementAt(i)).charValue()== 'a'){
        System.out.println("Character " + i + " in the stack is equal to " + myChar);
    }
}

Damn, sorry...that should have been :

for (int i = 0; i < stack.size(); i++){
   if (((Character)stack.elementAt(i)).charValue()== myChar){
       System.out.println("Character " + i + " in the stack is equal to " + myChar);
   }
}

Basically you iterate through the Stack getting each object and casting it to a Character (since all items in a Stack are upcast to Object) and then comapring it to a char.
