[JAVA - JLabel] executing a method based on contents of the variable


hi

i have a class which had a JPanel a JLabel and a JTextField ....

it has constructor methods for intializing the text of label and text field ...
it has set methods and get methods for setting and getting text, etc

the problem is ... i need this class to be generic ... i dont want to and i cant sit down and code all the possible methods for a JLabel object. i want to have a set method which accepts teo strings where the 1st is the property name like setBackground or setBounds and the second one is the parameters to be passed to the method

eg

if i need
label.setBackGround(Color.WHITE)
i want to call a function
setLabel (String a, String b)
where a = "setBackGround"
and b = "Color.White"

if i need
label.setBounds(10,10,100,20)
i want to call a function
setLabel(String a, String b)
where a = "setBounds"
and b = "10,10,100,20"

thanks a lot

Use the Java's Reflection API. Check the javadocs for such classes as Class, Method, Constructor, etc.
