首先,我们需要定义一个函数来计算给定非终结符号的Follow集。这个函数需要遍历所有产生式,找到包含该非终结符号的产生式,并将其Follow集添加到该非终结符号的Follow集中。 Set<String>calculateFollow(Stringsymbol){Set<String>followSet=newHashSet<>();for(String[]
HashSet<Character>>FirstSetX=newHashMap<>();//生成任何符号串的firststaticHashMap<Character,HashSet<Character>>FollowSet=newHashMap<>();//构造FOLLOW集合staticString[][] table;//预测分析表staticHashSet<Character>VnSet=newHashSet<>();//非终结符Vn集合staticHashSet<Character>Vt...
public class FirstFollow3 { public ArrayList<String[]> in=new ArrayList<String[]>();//这数据结构真是逼人绝路才去想到绝处逢生,哈哈,关键实现了可变长度文法接收,在这存放的是拆分后最简单的文法,也是由用户输入 public ArrayList<String[]> first = new ArrayList<String[]>();//包括左推导符和其First...
As we have seen from the last example, a Java program requires a lot of lines even for a simple program. For now, just remember every Java program we write will follow this structure. classMain{publicstaticvoidmain(String[] args){ ... } } We will write our code in place of...insid...
∴ FOLLOW(E) = {)} (6) Rule (3) cannot be applied to this production It has ) at the right end corner. But in rule (3) we should have a non-terminal at the right end corner. i.e., we cannot compare A →α B with F → (E). ...
