I have an assignment to write a program that uses the method triangleType that i must write to take three int inputs from the user and output the triangle type. In the method, I first need to sort the integers in ascending order so that the comparisons I am required to use will work correctly. I know I did the sorting part in the code correctly, because I tested it before I even started trying to determine the triangle type. I am required to use these comparisons to find the triangle type: "if A + B <= C, then the sides do not represent a valid triangle. if A = C (all the sides must be the same length) then the triangle is EQUILATERAL. if A = B or B = C, then the triangle is ISOSCELES; otherwise the triangle is SCALENE" For some reasons my if statements at the end of the triangleType method are not working correctly and I get all sorts of output, including "Invalid Triangle" plus other outputs no matter the integers that I enter.
package trianglemethod;
import javax.swing.JOptionPane;
public class TriangleMethod
{
public static void main(String[] args)
{
String wordaA, wordbB, wordcC, answer;
do
{
System.out.println("Please enter all 3 side lengths of the triangle in any order.");
wordaA = JOptionPane.showInputDialog("Enter side 1:");
wordbB = JOptionPane.showInputDialog("Enter side 2:");
wordcC = JOptionPane.showInputDialog("Enter side 3:");
int aA = Integer.parseInt(wordaA);
int bB = Integer.parseInt(wordbB);
int cC = Integer.parseInt(wordcC);
triangleType(aA,bB,cC);
System.out.println("Would you like to enter another triangle?");
answer = JOptionPane.showInputDialog("Would you like to enter another triangle?");
} while (answer.equalsIgnoreCase("yes"));
}
static void triangleType(int aA, int bB, int cC) {
int a=0, b=0, c=0;
if (aA > bB && aA > cC)
{
if (bB > cC)
{
a = cC;
b = bB;
c = aA;
}
else if (cC > bB)
{
a = bB;
b = cC;
c = aA;
}
}
if (bB > aA && bB > cC)
{
if (aA > cC)
{
a = cC;
b = aA;
c = bB;
}
else if (cC > aA)
{
a = aA;
b = cC;
c = bB;
}
}
if (cC > aA && cC > bB)
{
if (aA > bB)
{
a = bB;
b = aA;
c = cC;
}
else if (bB > aA)
{
a = aA;
b = bB;
c = cC;
}
}
if (a+b<=c)
{
JOptionPane.showMessageDialog(null,"Invalid Triangle");
} if (a==c) {
JOptionPane.showMessageDialog(null,"Triangle is Equilateral");
} if (a==b || b==c){
JOptionPane.showMessageDialog(null, "Triangle is Isosceles");
}
else {
JOptionPane.showMessageDialog(null,"Triangle is Scalene");
}
}
}
