Program Plan Intro

SQL:

  • SQL stands for “Structured Query Language”.
  • The current version of SQL is “ANSI SQL – 92”.
  • SQL is not a programming language. It is text-based and it is also called as data sublanguage.
    • In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
  • It contains constructs which are used to define and process database. They are executed using DBMS-supplied command prompt.
  • Some of the DBMS products provide GUI tools in order to perform tasks are as follows:
    •  SQL Server
    • Oracle Database
    • MySQL

Question 1 (15 Points) Inheritance: In this question, we are going to create a new subclass of the SimpleGeometricObject class, named Triangle. Create a SimpleGeometricObject.java and Copy the source code of the SimpleGeometricObject class from the following link: https://liveexample.pearsoncmg.com/html/SimpleGeometricObject.html TASK 1: Create a Triangle class that extends the SimpleGeometricObject class in Eclipse, following the below UML diagram. + base:double = 5 + height:double = 10 Triangle + Triangle() + Triangle(newBase: double, newHeight: double) + getArea(): double + setBase(): void + setHeight(): void + getBase(): double + getHeight(): double
Question 2 (10 Points): String vs. StringBuilder Create a Question2.java file and finish the following tasks: Task 1. a) Create a 1D array of integers to store 50 integers. b) Store values from 0 to 49 in the array you just created. c) Create a new String Object using no-arg constructor. d) Using for loop to add the array elements one by one to the String (one per loop iteration) Hint: to append an element to a String, use the + operator. e) Output the String on the console. Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). Please submit a screenshot. The screenshot should match the following example: 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849 it took 196708 nanoseconds to append 50 integers to the String.| Hint: You can use the following statements to record run-time. long begin, end, time; // we will measure time it took begin = System.nanoTime(); //we measure in nanoseconds. // put…
