问题

I have radio many radio group in my application and each group has many radio button i want to know how it is possible to assign one key board short cut or a combination of keyboard short cut for each button for example i want to put number 1 in first group first radio button so if i select the first group and press 1 in keyboard automatically first radio button will be selected. I am doing it now by tab, when i tab i select the focus radio button but it is not good when there are so many radio button because it takes time if i tab until the last radio button. How is this possible any suggestion is accepted

See AbstractButton.setMnemonic(char).

My bad..

This method is now obsolete, please use setMnemonic(int) to set the mnemonic for a button.
