Q3: Write a program that reads the integers between 1 and 100 and counts the occurrences of
each. Assume the input ends with 0. Here is a sample run of the program:
Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0
Enter
2 occurs 2 times
3 occurs 1 time
4 occurs 1 time
5 occurs 2 times
6 occurs 1 time
23 occurs 1 time
43 occurs 1 time
Note that if a number occurs more than one time, the plural word "times" is used in the output.
Q4: Design and implement a class named Triangle that extends GeometricObject. Theclass
contains:
• Three double data fields named sidel, side2, and side3 with default values 1.0 to denote
three sides of the triangle.
• A no-arg constructor that creates a default triangle.
• A constructor that creates a triangle with the specified sidel, side2, and side3.
• The accessor methods for all three data fields.
• A method named getPerimeter() that returns the perimeter of this triangle.
• A method named toString() that returns a string description for the triangle.
The toString() method is implemented as follows:
return "Triangle: sidel = " + sidel + " side2 = " + side2 + " side3 = " + side3;
Write a test program that prompts the user to enter three sides of the triangle, a color, and a
boolean value to indicate whether the triangle is filled. The program should create a Triangle
object with these sides and set the color and filled properties using the input. The program
should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
