You can get all field name by reflection
您可以通过反射获取所有字段名称
Class yourClass = YourClass.class
Field[] fields = yourClass.getFields();
for(Field f: fields){
f.getName();
}
or if you want mapping then go for Map
或者如果你想要映射然后去 Map
Map<String, String> propertyToValueMap
if you are trying to read method's local variable name, then it is not that simple to fetch also a signal that you are doing something wrong
如果您正在尝试读取方法的局部变量名称，那么获取一个表明您做错了的信号并不是那么简单

You can do it via reflection
你可以通过反射来做到
Class myClass = MyClass.class
Field field = myClass.getField("nameOfCar ");
System.out.println(field .getName());
To get all the fields without using the name you can do
要在不使用名称的情况下获取所有字段，您可以执行
Field[] myFields = myClass .getFields();
