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…
