public class ExpressionParser
extends Object
```
A parser for mathematical expressions. The parser class defines a method parse() which takes a string and returns an ExpressionNode that holds a representation of the expression. Parsing is implemented in the form of a recursive descent parser.

```
public ExpressionNode parse(String expression)
```
    Parse a mathematical expression in a string and return an ExpressionNode. This is a convenience method that first converts the string into a linked list of tokens using the expression tokenizer provided by the Tokenizer class.
    
    Parameters:
    
    expression - the string holding the input
    
    Returns:
    
    the internal representation of the expression in form of an expression tree made out of ExpressionNode objects
  - parse
```
public ExpressionNode parse(LinkedList<Token> tokens)
```
    Parse a mathematical expression in contained in a list of tokens and return an ExpressionNode.
    
    Parameters:
    
    tokens - a list of tokens holding the tokenized input
    
    Returns:
    
    the internal representation of the expression in form of an expression tree made out of ExpressionNode objects
