Question

For this question you will need to complete the methods to create a JavaFX GUI application that implements two String analysis algorithms. Each algorithm is activated when its associated button is pressed. They both take their input from the text typed by the user in a TextField and they both display their output via a Text component at the bottom of the GUI, which is initialized to “Choose a string methods as indicated in the partially completed class shown after the problem description. This is what the GUI looks like when it is first launched (no user interaction yet): 0 X - Enter your input string: Number of Digits Number of Lower-Case Choose a string algorithm First String Analysis Algorithm (Number of Digits):

Answer 1

Part 1 : Count Number of Digits in the given string and display it

String st = enter.getText();

int count = 0;

for (int i = 0; i < st.length() ; i++) {

   if (Character.isDigit(st.charAt(i))) {

        count++;

   }

}

display.setText("Number of Digits: "+str(count));

Part 2 : Count Number of Lower case alphabets in the given string and display it

String st = enter.getText();

int count = 0;

for (int i = 0; i < st.length() ; i++) {

   if (Character.isLowerCase(st.charAt(i))) {

        count++;

   }

}

display.setText("Number of Lower-Case: "+str(count));
