    Default FAQ: find variable in an array of objects

    My brain's gone finishing this morning, so I need a bit of help. Let's say I have a class that looks like this:
    Class Foo
    {
       int bar;
       int mooose;
     
       void Foo(int bar, int moose)
       {
           this.bar = bar;
           this.moose = moose;
       }
    }

    And then somewhere I create an array of objects, fooObj, of the type Foo and populate the variables of all objects in the array. How would I find which object has moose=42?

    The simple answer is to create a getter method for moose and see if that value is 42. If it's not, look at the next fooObj to see if it's moose is 42.

    public int getMoose()
    {
         return moose;
    }

    Note: If you have multiple fooObj's in the list with moose=42, this method will return the first one it finds. Depending on your application, this may or may not be what you want.
