(Solved) : Want Create Top Parser Able Analyze Java Style Class Declarations Following Examples Class Q35617381

We want to create a top-down parser which is able to analyze theJava style class declarations same as the following examples,

class Car extends Vehicle

public class JavaIsCrazy implements Factory, Builder,Listener

public final class President extends Person implementsOfficial

For this, we have the following grammar:

IndexGrammar Rule01C -> P R class identifier X Y2P -> public3P -> ε4F -> final5f -> ε6X -> extends identifier7X -> ε8Y -> implements I9Y -> ε10I -> identifier J11J -> , I12J -> ε

For this homework, you need to submit the following:

Compute Nullable values for all nonterminals )LHS) and allproduction rules (RHS). Submit the Nullable calculation rules andthe results. You do not need to submit the iterative table that isused for calculation.

To refer to productions you use production numbers mentionedabove, since using the names are lengthy. The following is anexample:

Instead of writing “Nullable (extends identifier)”, you write”Nullable (6)”.

Compute FIRST sets for all nonterminals (LHS) and all productionrules (RHS) You submit the FIRST calculation rules and the resultsets. You do not need to submit the iterative table that is usedfor calculation.

To refer to productions you use production numbers mentionedabove, since using the names are lengthy. The following is anexample:

Instead of writing “FIRST (extends identifier)”, you write”FIRST (6)”.

Compute FOLLOW sets for all nonterminals (LHS). (Don’t forget toadd a new start symbol and corresponding production rule includingthe end-of-input symbol, i.e. $. You submit the FOLLOW calculationrules for all and the result sets.

Submit the LL(1) parsing table for the grammar. (You added a newproduction rule with a new start symbol. For this production rule,we use the number 0 as its index number.)

To populate the table, you use rule numbers mentioned aboveinstead of writing the production rules in the table. For example,in the table, instead of writing “F -> final” you only write”4″.
