The*_*rub 4 java android arraylist
我是Java的新手,我目前正在使用Android Studio.我只是无法理解为什么.add不工作.主题和作业只是自定义类.问题是弹出"无法解析符号'添加'"消息,整个过程失败.我导入了java.util.ArrayList.
ArrayList<Subject> mSubjects = new ArrayList<Subject>();
Subject cheese = new Subject("Cheese",new Assignment[]{new Assignment("Test 1",1.0f,1.0f,1.0f),new Assignment("Test 2",100f,100f,1.0f)},100f,4.0f);
mSubjects.add(cheese);
