Answer 1

You button is defined twice, once as a local variable and once as an instance variable

JButton regMaterijalaButt = new JButton("Registar materijala");

Above is where you are defining the button as a local variable

if(event.getSource() == regMaterijalaButt )

Your ActionListener is referencing the instance variable.

Your code should be:

//JButton regMaterijalaButt = new JButton("Registar materijala");
regMaterijalaButt = new JButton("Registar materijala");
