Problem 2: Triangle Recognition (If, If … Else)

Create Triangle Recognition on the right side of the app. It should ask the user to enter three points. You will need six text fields – three pairs of two. Each pair will represent a point (x, y). The coordinates of the points should be double variables. Using these points, the app should communicate to the user if the points form a triangle. Once it is confirmed that the points form a triangle the app needs to identify the type of triangle that was formed: Equilateral, Scalene, Isosceles, Right-Angled, Obtuse, or any combination. It has to communicate this to the user. Then it has to print the length of the sides of the triangle using the distance formula.

Problem 1: Number to Words (Loop with If, If … Else)

Create Number to Words on the left side of the app. It should ask the user to enter an integer that is between zero and one million inclusive. The user can then click a button that will convert the number into words and displays these words. For example, if the user enters 12345 the app will print “twelve thousand three hundred forty five”. Note that there is no “and” in the words and no commas in the input. Make sure that the app recognizes when the user enters an invalid input and presents a well-written error message to alert the user of the error. Please make sure that the error also helps the user enter the correct values. Only use if else and else if statements.

what is the output of the following code segment? show your work
public int DoIt(){
int []a=new int[10];
int temp=a[2];
try{
String a=null;
String b=a.toUpperCase();
System.out.println("\n departing DoIt()");
System.out.println("\n in try zone");
}
