Questions and Answers

What condition must be met for the program to classify the input angles as a triangle?

  • The individual angles must all be less than 90 degrees.
  • The sum of the angles must equal 90 degrees.
  • The sum of the angles must be greater than 180 degrees.
  • The sum of the angles must be exactly 180 degrees. (correct)

    • How does the program identify an acute triangle?

  • At least one angle is exactly 90 degrees.
  • At least one angle is greater than 90 degrees.
  • All angles are equal to 60 degrees.
  • All angles are less than 90 degrees. (correct)

    • Which part of the program checks whether the triangle's angles are valid?

  • The print statement indicating the triangle type.
  • The switch statement evaluating operational modes.
  • The if condition checking if a + b + c > 180.
  • The if condition checking if a + b + c == 180. (correct)

    Study Notes

    Java Program - Triangle Classification

    • Program Description: Classifies a triangle based on its angles (acute, right, obtuse) given three angles as input.

    • Import Statement: Imports java.util.* for input/output operations.

    • Class Definition: Defines a public class named Triangle.

    • Main Method:

      • Initializes a Scanner object to read input from the console.
      • Prompts the user to enter three angles.
      • Reads the angles using sc.nextInt() and stores them in variables a, b, and c.
      • Checks if the sum of angles is 180 degrees. If not, output "Triangle is not possible".
      • Conditional Statements: Uses if-else statements to classify the triangle:
        • If all angles are less than 90 degrees, the triangle is acute.
        • If all angles are equal to 90, the triangle is right-angled.
        • If any angle is greater than 90 degrees, the triangle is obtuse-angled.

    • Output: Prints the type of triangle (acute, right, obtuse, or not possible) to the console using s.o.pln().

    Features

    • Object-Oriented: The program is potentially object-oriented based on the mention of object-oriented and robust/secure elements from another section.
    • Platform Independent: The code is designed to work across various platforms without modification.

    Errors

    • Input Validation: The program lacks validation that the input represents valid angles. For example, it does not check that the input values are positive and their sum is 180 to ensure it is a valid triangle. Also, each individual angle greater than 0 and less than 180.
