Java variables: The java variables are the containers to hold a value during the program execution. The variables can be declared in different data type according to the need. The variables are names to some memory location and these memory locations can hold values. The variables can have the data type, integer, character, float, double and so on. If a variable is declared as “int” data type, then this variable will hold an integer value. Likewise, “float” data type variable will hold a floating point value and so on. The value of a variable may change when the program start the execution if the change is mentioned in the program code..

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…
