The document describes the step-by-step parsing of the mathematical expression "(1 + 20) * 2" according to a specified grammar. The parsing breaks the expression down into a stack of syntactic elements including number literals, additions, multiplications, and primaries according to the grammar rules.

Addition returns Expression:
Multiplication ({AdditionalExpression.left=current} '+' right=Multiplication)*;
Multiplication returns Expression:
PrimaryExpression ({MultiplyExpression.left=current} '*' right=PrimaryExpression)*;
PrimaryExpression returns Expression:

Step 1 The Pair Class Many times in writing software we come across p.pdf

Step 1 The Pair Class Many times in writing software we come across problems that require us of values. For to store a pair example, a coordinate system would require an x, y value pair or a hash key value pair Your task on this assignment is table as a data, one type but to create a simple template pair class called Pair that has two type parameters. You should call these parameters F and s. Functionality Constructor You should create a working constructor that takes two type parameters one for each of the pair values. get First This is an accessor method that will return the first of the pair values. get second This is an accessor method that will return the second of the pair values. set First This is a mutator method that will set the first pair value setsecond This is a mutator method that will set the second pair value Solution Pair.java public class Pair { private F first; //first member of pair private S second; //second member of pair public Pair(F first, S second) { this.first = first; this.second = second; } public void setFirst(F first) { this.first = first; } public void setSecond(S second) { this.second = second; } public F getFirst() { return first; } public S getSecond() { return second; } } LinkedList.java template class Node { private T data; //the object information private Node* next; //pointer to the next node element public void setData(T val) { this.data = val; } public void setNextNull() { this.next = NULL; } public void setNext(Node *tmp) { this.next = tmp; } public Node* getNext() { return this.next; } }; template class LinkedList extends Node { private Node *head = new Node; private Node *tail = new Node; public LinkedList() { head = NULL; tail = NULL; } public ~LinkedList() { } //Method adds info to the end of the list public void append(T info) { if(head == NULL) //if our list is currently empty { head = new Node; //Create new node of type T head->setData(info); tail = head; } else //if not empty add to the end and move the tail { Node* temp = new Node; temp->setData(info); temp->setNextNull(); tail->setNext(temp); tail = tail->getNext(); } } public void addFront(T info) { if(head == NULL) //if our list is currently empty { head = new Node; //Create new node of type T head->setData(info); tail = head; } else //if not empty add to the end and move the tail { Node* temp = new Node; temp->setData(info); temp->setNext(head); head = temp; } } //insert after given node public void insert(Node *node,T info) { Node *temp = new Node; temp->setData(info); temp->setNext(node->getNext()); node->setNext(temp); } public void delete(Node *node) { Node *temp = new Node; temp = head; while(temp->getNext() != node && temp->getNext() ) { temp = temp->getNext(); } if(temp) { temp->setNext(node->getNext()); delete node; } } public Integer size(Node *head) { int sz=0; Node * temp = new Node; temp = head; while(temp) { sz++; temp = temp->getNext(); } return sz; } } PairList.java public class PairList< E, F > extends LinkedList< Pair< E,.

Picture of output is given below The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent, e.g., the term 2x4 has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructor and destructor functions as well as set, get, and print functions. The class should also provide the following overloaded operator capabilities: a) Overload the addition operator (+) to add two Polynomials. b) Overload the subtraction operator (-) to subtract two Polynomials. c) Overload the assignment operator to assign one Polynomial to another. d) Overload the multiplication operator (*) to multiply two Polynomials. e) Overload the addition assignment operator (+=), subtraction assignment operator (-=), and multiplication assignment operator (*=).

Auto-GWT : Better GWT Programming with Xtend

Sven Efftinge

Presentation from GWT.create 2015 EU Auto-GWT (auto-gwt.org) is a library for the Google Web Toolkit, that frees your code from unneccessary and complicated boilerplate and at the same time pushes the IDE capabilities to a new level. Auto-GWT is based on Xtend (xtendlang.org). Xtend is a modern programming language that is 100% compatibly with existing Java libraries and even translates to readable Java source code. With it's slick syntax and powerful features such as lambdas, operator overloading and compile-time macros you can turn any verbose piece of Java code into a small and elegant piece of expressive Xtend code. In this session we will show how Xtend can be used to program GWT applications and how well the typical GWT idioms are supported by the language.

Functional programming with Xtend

Sven Efftinge

At least since the release of Java 8, functional programming has become mainstream in the Java community. Things like collection processing, lazy evaluation and concurrent programming are much easier to describe in a functional style than in the traditional procedural or object-oriented way. Xtend is a Java dialect hosted at Eclipse. Designed to remove the syntactic noise, it offers a superior syntax and additional abstractions to provide the full power of functional programming to Java developers. As it compiles to Java 5 code, it will enable functional programming even for Android and GWT developers. In this tutorial, you will learn the basic principles of functional programming and the Xtend idioms to write code the functional way: concise, easy to understand, and yet powerful. No prior knowledge of functional programming or Xtend required.

Gwt and Xtend

Everybody knows : Web is the platform of the future. Developing for the browser unfortunately requires us to learn and write JavaScript. Not only that but we also have to integrate the JavaScript client code with the server side, which often runs on the JVM (i.e. is written in Java). So we have to work in two different languages with completely different tools and APIs, and cannot share code between the client and the server. The Google Web Toolkit (GWT) provides a way to write your client side web application entirely in Java and have it automatically translated to fast and compact JavaScript. It allows you to access all the browser functionality through a statically typed API. You only have to learn and use one language and you can use your code on the client as well as on the server. The downside : Java is a bad match for the asynchronous programming model required on the browser and generally forces us to write and read a lot of boilerplate code. In this session you'll see how programming GWT applications with Eclipse Xtend provides the best of both worlds: Static typing with advanced IDE support meets a powerful and expressive language - right at your finger tips.
