(Manipulating a Stream<Invoice )

  • Use the class Invoice to create a List of Invoice objects.
  • Use the sample data shown in the Fig.
  • Class Invoice includes four properties
  • PartNumber (type int ),
  • PartDescription (type String ),
  • Quantity of the item being purchased (type int ) and
  • Price (type double ).
  • Perform the following queries on the List of Invoice objects and display the results:
  • Use lambdas and streams to sort the Invoice objects by PartDescription , then display the results.
  • Use lambdas and streams to sort the Invoice objects by Price , then display the results.
  • Use lambdas and streams to map each Invoice to its PartDescription and Quantity , sort the results by Quantity , then display the results.
  • Use lambdas and streams to map each Invoice to its PartDescription and the value of the Invoice (i.e., Quantity * Price ). Order the results by Invoice value.
  • Modify Part (d) to select the Invoice values in the range $200 to $500.

[SOLVED] Tape for a Turing Machine using Doubly-linked List in Java with full source code

By Anonymous -
Tape for a Turing Machine (Doubly-linked List) Short exercise in which you will code part of an existing project. In this case, you will be working with a doubly-linked list. To make this topic more interesting, the list that you work on will be part of a Turing Machine. A Turing Machine is a kind of very simple, abstract computing device that was introduced in the 1930's by Alan Turing as a way of studying computation and its limitations. The classes that you need for the lab are in a package named turing. You will define a new class named Tape in this package. You can find the Java source in the code directory. You should copy this directory into an Eclipse project. There will be errors, since the existing classes depend on the Tape class, which you have not yet written. Don't forget the Javadoc comments. A Class for Turing Machine Tapes A Turing machine works on a "tape" that is used for both input and output. The tape is made up of little squares called cell...

[SOLVED] ICT285 Databases TMA 2017 Assignment 1 | Relational Algebra, Database Design & Implementation

By Anonymous -
Relational Algebra A database records information about athletes competing at the Olympics. An athlete competes for a particular country in one or more events. Events take place at a scheduled day and time in a particular venue. The result (rank) is recorded for all athletes in the final of the event. The medal (gold, silver or bronze) is also recorded for the medal winners in the event. Note that we are not considering team sports or heats in this example – only individuals competing in the finals. The schema for this database is as follows: (Note that primary keys are shown underlined, foreign keys in bold). ATHLETE ( AthleteNo , AthleteName, CountryName) COUNTRY ( CountryName , NumberOfCompetitors) EVENT (EventName, ScheduledStart, VenueName ) VENUE (VenueName, City, Capacity) FINAL ( AthleteNo , EventName , Rank, Medal) Provide relational algebra (NOT SQL) queries to find the following informaList the name and country of all athletes. List the event name and scheduled...
