问题描述
我有25个jButton,我想从循环中更改其文本.这是我的1个按钮的代码.
I have 25 jButtons and i want to change their texts from a loop. Here is my code for 1 button..
void changeText(){
jButton1.setText(jButton1.getText().toUpperCase());
}
我想对所有其他按钮执行相同操作,而不必为每个按钮编写方法.
I want to do the same for all other buttons without writing a method for each.
是否可以使用类似的东西?
Is it possible to use something like this?
void changeText(){
for(int i=0;i<25;i++){
String x = "jButton"+i;
x.setText(x.getText().toUpperCase());
}
}
这肯定行不通.请给我建议一种方法.
Surely this wont work. Please suggest me a method.
推荐答案
您可以通过将按钮添加到集合中来实现.
You can do this by adding the buttons to a collection.
类似这样的东西:
// initialization of jbuttons:
List<JButton> buttons = new ArrayList<JButton>();
JButton jbutton1 = new JButton();
// .. set properties
buttons.add(jbutton1);
// add more jbuttons to the list
稍后您可以遍历按钮列表:
Later you can iterate over the list of buttons:
for (JButton button : buttons) {
button.setText(button.getText().toUpperCase());
}
