U can use one of the following methods

Component[] getComponets() method, which returns an array of all the
components.

or

int iCompCount = someContainer.getcomponentCount();
for ( int loop = 0; loop < iCompCount; loop++)
Object o = someContainer.getComponent(loop);

and i forgot to tell u can always use instanceof operator..

for ( int loop = 0; loop < iCompCount; loop++)
{
Object o = someContainer.getComponent(loop);
if( o instanceof someComponentType)
do what needed..
}
