I've got 4 Buttons on my Form and a menu bar with an option to change their colours. In my code I change colour of each one individually, like this:
jButton1.setBackground(Color.cyan);
jButton2.setBackground(Color.cyan);
jButton3.setBackground(Color.cyan);
jButton4.setBackground(Color.cyan);
Which isn't a problem right now but might become one if I add more of them. So is there a way to change the colour of all present buttons at once?
You can try to create an array of jbuttons such as:
JButton[] buttonsArr = new JButton[4];
and then you can loop on the items and set color of text for all of them.
Such as:
for(int i = 0;i < 4;i++){
buttonsArr[i] = new JButton(String.valueOf(i));
// Or you can add the color such as
buttonsArr[i].setBackground(Color.cyan);
}
Another solution is to declare a Color Variable and use it as a global variable or as Enum such as:
Color globalColor = new Color(187, 157, 177);
jButton1.setBackground(globalColor);
jButton2.setBackground(globalColor);
jButton3.setBackground(globalColor);
jButton4.setBackground(globalColor);
And whenever you need to change it you can change it easily by changing it is value.
