- A class Scanner in Java can be used to get user input and itsmethods can be used after the following statement isexecuted:Scanner input = new Scanner(System.in);One of its methodsnextDouble() returns the next double value from the keyboard. Nowyou are requested to write a method enterHeight() which displaysthe message “Input height:
- and uses the method input.nextDouble() to get the user input.The process should be repeated until the input is non-negative.Finally the input should be returned. You can assume theaforementioned statement starting with Scanner has already beenexecuted.
- Write a method category(double height) which returns a suitabletype in string form according to the following:
Condition
Type
height >= 200
Tall
100 <= height < 200

Question 5
A method secret() of a class F is shown below:
public intsecret(String[] stringArray, int n) { int num = 0;
for (int i=0; i<stringArray.length;i++)
if (stringArray[i].indexOf(“a”, n)>= 0)
num++;
return num;
}
A program segment using the method is:
F f = new F();
String[] array01 ={“an”, “easy”, “exam”, “on”, “Java”};System.out.println(f.secret(array01, 2)); array01 = newString[0];
System.out.println(f.secret(array01,3));
- Write down the output when the above segment is executed.
- Explain, in a paragraph, what is the purpose of the methodsecret().

The first few lines of a class PrimeNumber are shown below:
public classPrimeNumber extends JFrame implements ActionListener { privateJLabel label = new JLabel(“2”);
private JButton button = newJButton(“Next Prime”);
The expected appearance of the GUI,which includes a label and a button, is shown on the right and thelayout manager is the FlowLayout manager.
- Write the constructor PrimeNumber() to generate the GUI and addthe object itself as the action listener of the button. When thewindow is closed, the program should terminate.
- When the button is pressed, the next (larger) prime number isdisplayed on the label. Write the method actionPerformed() toperform this action.
