Answer 1

Every 81 lines of this code to be explained in details: are you kiding? :o

You'll be better adviced to make a google search about tokenization and code languages parsing and read many articles/ressources about, because this is a wide and deep topic... also, you should have a minimal Java (or other language if not) practice background to understand both the code itself and the principles ;)

Answer 2

Denise Roßberg sure it will thank u😊

Answer 3

To explain every line would be a bit hard. ;)

But maybe this code helps you to understand the overriden methods:

Denise Roßberg i have knowledge about java n its basic concepts but my assignment is based on this class and i am using this type of class first time so there is confusion any ways i will search related topics on google☺

Answer 6

notice Token class override nothing

Answer 7

zemiak

The class overrides equals(), hashCode() and toString().

Edit: I did not test the class so I am not sure if the implementations are correct.

Answer 8

Komal Ramzan

The rest should be found in the java course.

You will need the lesson about enums.

The lesson about constructor:

public Classname() is a constructor for example:
public Token()

You have three. If I am correct there is only a lesson about method overloading but not constructor overloading. But it is similar.

Then you just need to read the lesson about methods.

Answer 9

there are different ways how to create Token:

new Token(10.0); with number, as OPERAND, precedence 0
new Token("+"); with string, as OPERATOR, precedence 0(+-) or 2(*/)
new Token("("); with string, as PAREN, precedence -1

new Token(token1); with other token
