    I have created a JComboBox with its Items as a list of "M" numbers ie.
    M1,M2,M3.......throgh too M110 (thes are the messier objects, a
    catolouge of deep sky objects) the user selects of of these and views
    it aswell as infomation. The program also has a JTextFiels which
    allows the user to enter the M number. The problem i have is checking
    that what the user has entered is valid, that being an M followed by 1
    - 110 Nothing else, i thought of checking it against the items in the
    comboBox with itemAt() but i cudnt work out a way of looping through
    them, and using that within the if() Expression.... please help.
