Just use an array list type of structure to store all your checkboxes. Access them using an index later. If you want to name them based on some property of disponibility, you can use a map to store the checkboxes.
只需使用数组列表类型的结构来存储所有复选框。稍后使用索引访问它们。如果要根据某些可用性属性对它们进行命名,可以使用地图来存储复选框。
List<JCheckBox> list = new ArrayList<>();
for(disponibility prov: dis){
JCheckBox check=new JCheckBox();
check.setBounds(30,156,97,33);
list.add(check);
}
//Later access nth checkbox
list.get(n).setEnabled(true);
