Question
4. Write a java
a. Prompt the user to enter a password (a string, use Scanner class to read the password)
b. Check the validity of the password by calling a method, named passValidity()
c. Return an appropriate message (i.e. password is valid or invalid) to the main() method. The
main() method will print the message.
The passValidity() method will:
a. take the password as the input parameter,
b. check the validity as per the following rule:
• the password string must have at least eight characters
• the password must have at least one alphabet
• the password must contain at least one digit
• the password must contain at least one special character from @, #, $, and &
c. return an appropriate message to the main() method.
Sample output (assuming the input is ab459#de0):
The password is valid
Sample output (assuming the input is abcd#de&ui):
The password is invalid

- Write a java program called Sales considering the following directions and the sample run. Practice here first the write answer on the answer sheet. Also, make sure to distinguish high and low caps as Java is case - sensitive. - import and declare a Scanner class - declare three floating – point variables named price, discount, and discountPrice - ask the user for the price (print statement) and get the price (Scanner) from the user - calculate the discount if price is less than 100, then the discount is 10% of price, else discount is 14% of price - print the discounted prices for the item Sample Run Enter the price 90.0 The discount price is 81.0 Enter the price 200.0 The discount price is 172.0arrow_forwardIn Java please.

- 3. Consider how a Java program reads input from the keyboard. O O Give three methods from the Scanner class that you can use to read input from the keyboard with Scanner sc = new Scanner(System.in); Which method is used to read an integer with the scanner sc in 3a? Can you use the Scanner class to read an integer twice from the keyboard with the method you identified in 3b? If so, give the code that will allow that to happen. If not, explain what your program should do to use that word multiple times. When mixing Scanner methods in a program (i.e., calling different methods consecutively), which Scanner method will appear to read nothing from the keyboard if following another Scanner method? (If you do not know, put a question mark and move on). Consider what happens when your Java program writes output to the monitor (console). Give two methods that you can use to write output to the monitor.arrow_forwardplease use java to answer the following questionarrow_forwardStart with the code below and complete the getInt method. The method should prompt the user to enter an integer. Scan the input the user types. If the input is not an int, throw an IOException; otherwise, return the int. In the main program, invoke the getInt method, use try-catch block to catch the IOException. import java.util.*; import java.io.*; public class ReadInteger{ public static void main() { // your code goes here } public static int getInt() throws IOException { // your code goes here } }arrow_forward
