Java For Loop Problems

Question

JButton nupp0 = new JButton(); // Teen nupu objektid, rida 54 
JButton nupp1 = new JButton();
JButton nupp2 = new JButton();
JButton nupp3 = new JButton();
JButton nupp4 = new JButton();
JButton nupp5 = new JButton();
JButton nupp6 = new JButton();
JButton nupp7 = new JButton();

public JButton nupud[] = { nupp0, nupp1, nupp2, nupp3, nupp4, nupp5, nupp6, nupp7 };

I was told to create this pieace of code in for loop, Ive tried many ways, but I cant get it to work. Any Ideas?

These are my 2 tries:

for (int i =0 ; i < nupud.length ; i++) {
    JButton nupud[i] = new JButton;     
}

for (int i = 0 ; i < nupud.length ; i++) {
    nupud[i] = new JButton();
}

Answer 1

Just new up the array first:

JButton[] nupud = new JButton[8];
for (int i = 0 ; i < nupud.length; i++){
    nupud[i] = new JButton();
}
