1)-Write a Java program that reads values for three sides of a triangle. The sides will form a triangle if the values are greater than zero and the sum of any two sides is greater than the third side. The program should classify the triangle as either isosceles, scalene, equilateral, or both right-angled and scalene according to the following rules: • An equilateral triangle has all sides equal • An isosceles triangle has only two sides equal • A scalene triangle has no sides equal • In a right-angled triangle, the square of the longest side must be equal to the sum of the squares of the other two sides. (i.e., if c is the longest side among sides a, b and c of a right-angled triangle then c2 = a2 + b2

triangle if the values are greater than zero and the sum of any two sides is greater than the
third side. The program should classify the triangle as either isosceles, scalene, equilateral, or
both right-angled and scalene according to the following rules:
• An equilateral triangle has all sides equal
• An isosceles triangle has only two sides equal
• A scalene triangle has no sides equal
• In a right-angled triangle, the square of the longest side must be equal to the sum
of the squares of the other two sides. (i.e., if c is the longest side among sides a, b
and c of a right-angled triangle then c2 = a2 + b2
).
Here are some specific requirements:
• Include a boolean method named checkTriangle, which accepts three
double values as arguments and returns true if they form a triangle (otherwise
returns false)
• Include a value returning method named getLongest, which accepts three
double values as arguments and returns the largest value.
• Include a boolean method named checkRightTriangle, which accepts
three double values as arguments and returns true if they form a right angled
triangle (otherwise returns false)
Display an appropriate message indicating the type of triangle. Save the program as
Triangle.java. Extend the program so that it provides the user with an option to
continue running it.
Here are two sample runs:
Run 1:
Enter three sides (doubles): 1.0 1.0 10.0
Input is invalid. Triangle cannot be formed.
Do you want to run the program again? (Y/N)
N
Run2:
Enter three sides (doubles): 3.0 4.0 5.0
This is a right-angled scalene triangle
Do you want to run the program again? (Y/N)
Y
Enter three sides (doubles): 5.0 5.0 4.0
This is an isosceles triangle
Do you want to run the program again? (Y/N)
N
