Discuss the advantages and limitations of sequential programming with your teammates

我认为顺序编程的优点是它可以很容易地完成复杂的任务,而且可以让程序员更容易理解。但是,顺序编程也有一些局限性,比如它不能处理多任务,而且可能会拖慢程序的执行速度。因此,我建议我们在和团队成员讨论顺序编程的优点和缺点时,要考虑到这些局限性。

Prepare a 5-minute video to show the execution of your program on the lab board followed by an explanation of your code in Keil uVision (See Scenario 1 below). You may also discuss the testing/simulation/debugging of your program. This video should be submitted on QMPlus (60%). Please begin with a clear camera view of yourself, introducing your name (in Pinyin) and QMUL student ID. Scenario 1: Use the RealTerm serial terminal to transmit you name in Pinyin in CAPITAL letters. Upon receiving the first letter, the programme should start sending the Morse code of incoming letters First-In-First-Out.分析下需求
根据你的问题,我理解你是在询问如何执行一个程序并在Keil uVision中解释代码,然后制作一个展示程序执行和代码解释的5分钟视频,并且视频需要包括测试、仿真和调试的过程。具体要求是使用RealTerm串行终端发送大写拼音姓名,接收到第一个字母后,程序应该按照先进先出的原则发送对应字母的莫尔斯码。视频需要包括自我介绍和学生ID,并在开始展示之前保持清晰的摄像头视角。
1.Discuss how and why the SecurityManager class for JVM check methods can be defined differently based on context.. 2.The library class Collections contains a method sort with the following type signature. public static <T> void sort (T[] a, Comparator <? super T> c); The Comparator interface contains the following method which returns a negative integer, zero or a positive integer according to whether o1 is considered to be before, equal to or after o2 in a proposed ordering. int compare (T o1, T o2) ; What does the identifier T mean in the declaration of the method sort? Illustrate your answer with an example. 3.What does the notation <? super T> mean in the declaration of sort? Again, illustrate your answer with an example. 4.Explain the concept of an anonymous inner class in Java using a method call example. 5.Convert the method call example using an anonymous inner class to a lambda expression. Give the code required for this. 6.In what types of situations might you prefer to use an anonymous class instead of a lambda expression, and vice versa? 7.Explain (auto)boxing and (auto)unboxing in Java? 8.What does the annotation @Override mean in Java? What are the benefits of adding it? 9.What are wildcards in Java and how are they used in generic programming? 10.Can you explain the bounded wildcards, and provide an example
1. The SecurityManager class for JVM check methods can be defined differently based on context because different contexts may have different security requirements and restrictions. For example, a web application may need to restrict access to certain resources, while a desktop application may not have the same restrictions.
2. The identifier T in the declaration of the method sort represents a generic type parameter that can be replaced with any type when the method is called. For example, if we have an array of integers, we can call the sort method like this:
```
Integer[] arr = {3, 1, 4, 1, 5, 9, 2, 6, 5, 3};
Comparator<Integer> c = Comparator.naturalOrder();
Collections.sort(arr, c);
```
3. The notation <? super T> in the declaration of sort means that the Comparator can accept any type that is a superclass of T. For example, if we have a class Animal and a subclass Dog, we can use a Comparator that accepts any superclass of Dog to sort an array of Dogs:
```
Dog[] dogs = ...;
Comparator<Animal> c = ...;
Collections.sort(dogs, c);
```
4. An anonymous inner class in Java is a class that is defined and instantiated at the same time, without a separate class definition. For example, we can define an anonymous inner class to implement an interface and pass it as an argument to a method:
```
Runnable r = new Runnable() {
public void run() {
System.out.println("Hello, world!");
}
};
r.run();
```
5. The same example using a lambda expression would look like this:
```
Runnable r = () -> System.out.println("Hello, world!");
r.run();
```
6. You might prefer to use an anonymous class instead of a lambda expression when you need to define a class that has additional behavior or state beyond the method being called. You might prefer to use a lambda expression when you only need to define a single method and want to keep the code more concise.
7. (Auto)boxing and (auto)unboxing in Java refer to the automatic conversion between primitive types and their corresponding object wrapper types. For example, an int can be automatically boxed to an Integer, and an Integer can be automatically unboxed to an int.
8. The annotation @Override in Java indicates that a method is intended to override a method in a superclass or interface. Adding this annotation can help catch errors at compile time and make the code more readable.
9. Wildcards in Java are used in generic programming to allow a generic type to accept any type that meets a certain criteria. For example, a List<? extends Number> can accept a List of any subclass of Number.
10. Bounded wildcards in Java restrict the types that can be used with a generic type parameter. For example, a List<? extends Number> can only accept types that are subclasses of Number, while a List<? super Integer> can accept types that are superclasses of Integer. An example of using a bounded wildcard would be:
```
public static double sum(List<? extends Number> list) {
double total = 0.0;
for (Number n : list) {
total += n.doubleValue();
}
return total;
}
```
