Selection Statements A selection statement offers the methods of selecting among two or more execution paths within a program. These statements are basic and essential parts of all languages, as proven by Böhm and Jacopini. The two basic categories of selection statements are: • Two-way selectors (if-statement) o Design Issues o Control Expression o Clause Form o Nesting Selectors o Selector Expressions • Multiple-way selectors (case-statement) o Design Issues o Examples of Multiple Selectors o

1. Problem 1 (20 points): Why is the execution environment of a Java class called a virtual machine? How does this virtual machine compare to a real machine running code written in C? Answer: Java files are executed on Java Virtual Machine which is not a real machine. This is a software application which acts like a real machine and make a complete environment like heap, memory, stack, CPU etc virtually. Basically it is layer of software between the OS and the application program. That's why it

certain tasks. Firstly, we have to know what is programming language? The term usually refers to programming languages, such as high BASIC, C, C ++, COBOL, FORTRAN, Ada and Pascal. Every language has a unique set of keywords (words that are used) and a special syntax for organizing the program instructions. Some languages are defined in the specification (e.g., the C programming language defined ISO), while other languages (such as Perl) dominant application is considered as a reference.

Once the SWOT analysis has been done for the candidate, it has concluded with a detailed list of Strengths, Weaknesses, Opportunities, and Threats. The following step is indispensable for making that information useful. First of all, it must be made a selection of the most influential points in each category in order to reduce, or increase, the impact of these aspects for reaching the goal of the candidate. As soon as the most critical points have been chosen correctly, the candidate must face up

Scala conditionals follow the same pattern that is found in most other languages. It supports “if”, “else” and “else if” statements. If statements are written using the format “if ( condition ) { body }” this statement can be followed with optional “else if” statements and then optionally with a single “else” case at the end. Scala also provides a very powerful feature for matching a variable by its value or type. Instead of using numerous if statements you can use a single “match” statementOdersky

Introduction In the current Society and Web Development Industry, Web developers are using well known frameworks such as Angular2 and Java programming when it comes to building Web Applications. Angular2 is a JavaScript framework for building client-side Applications using HTML, CSS and a programming language such as JavaScript. On the other end, Java is a platform as well as a programming language which can be used in back end of Web Applications. Angular2 and java are so very popular in web development

Assignment Instructions: • Develop a routine to identify and remove stop words • Implement a porter stemmer to stem the tokens processed by your indexer routine. • Remove (do not process) any term that begins with a punctuation character • Determine the term frequency (tft,d) for each unique term in each document in the collection to be included in the inverted index. • Determine the document frequency (dft) which is a count of the number of documents from within the collection that each unique inverted
