go take a look at the number handling routines in the JDK package, eg. java.lang.Integer and look at the APIs available

using the Constructor
Integer intNum = new Integer(String number_you_want_to_convert);

or to use the API directly
Integer the_answer = Integer.getInteger(String number_you_want_to_convert);

or
int the_answer = Integer.parseInt(String number_you_want_to_convert);

2)
Label labeltest = new Label("Test");
labeltest.setVisible(false);

set the setVisible() to false to hide it setVisible(true) to show it
