This tictactoe program is a 2player game. The GUI i made are frame and buttons after that i started coding. Actually my program is working in this kind of coding.
private String letter= " ";
private int count= 0;
private void btn7ActionPerformed(java.awt.event.ActionEvent evt) {
count++;
if(count == 1 || count == 3 || count == 5 || count == 7 || count == 9){
letter = "X";
} else if(count == 2 || count == 4 || count == 6 || count == 8 || count == 10){
letter = "O";
}
if(evt.getSource() == btn1){
btn1.setText(letter);
} else if(evt.getSource() == btn2){
btn2.setText(letter);
} else if(evt.getSource() == btn3){
btn3.setText(letter);
} else if(evt.getSource() == btn4){
btn4.setText(letter);
} else if(evt.getSource() == btn5){
btn5.setText(letter);
} else if(evt.getSource() == btn6){
btn6.setText(letter);
} else if(evt.getSource() == btn7){
btn7.setText(letter);
} else if(evt.getSource() == btn8){
btn8.setText(letter);
} else if(evt.getSource() == btn9){
btn9.setText(letter);
}
}
private void btn1ActionPerformed(java.awt.event.ActionEvent evt) {
count++;
if(count == 1 || count == 3 || count == 5 || count == 7 || count == 9){
letter = "X";
} else if(count == 2 || count == 4 || count == 6 || count == 8 || count == 10){
letter = "O";
}
if(evt.getSource() == btn1){
btn1.setText(letter);
} else if(evt.getSource() == btn2){
btn2.setText(letter);
} else if(evt.getSource() == btn3){
btn3.setText(letter);
} else if(evt.getSource() == btn4){
btn4.setText(letter);
} else if(evt.getSource() == btn5){
btn5.setText(letter);
} else if(evt.getSource() == btn6){
btn6.setText(letter);
} else if(evt.getSource() == btn7){
btn7.setText(letter);
} else if(evt.getSource() == btn8){
btn8.setText(letter);
} else if(evt.getSource() == btn9){
btn9.setText(letter);
Yeah, it is actually working but my problem with this codes is I need to put the codes in every button e.g. button7, button1 (these just the example of my buttons) which is the codes are the action performed of the button.
I want only a single command that each button perform and I dont want to copy paste in every buttons because they are identical codes. I think there is a code to do that, what do you think? Please help!
So basically, you want to collapse you logic into a single handler. This handler needs a single reference to the button that it is acting on...
Something like...
public class ActionHandler implements ActionListener {
private JButton master;
public ActionHandler(JButton master) {
this.master = master;
}
protected void setText(String text) {
master.setText(text);
}
@Override
public void actionPerformed(ActionEvent e) {
String text = null;
count++;
if (count / 2f == Math.round(count / 2f)) {
text = "O";
} else {
text = "X";
}
setText(text);
}
}
Now you setup code may be different then this, this is just an example...
buttons = new JButton[9]; // You can use this to reset the board ;)
setLayout(new GridLayout(3, 3));
for (int index = 0; index < 9; index++) {
JButton btn = new JButton(Integer.toString(index));
buttons[index] = btn;
btn.addActionListener(new ActionHandler(btn));
add(btn);
}
The basic idea is that as you create a new button, you assign it's own ActionHandler passing it a reference of the button. This allows the action handler to control the button based on the state of the game.
