Have the user enter a password. The code loops through each character in the string. Add code in the middle section to count how many digits, uppercase and lowercase characters there are. If they have at least one of each, print that their password is ok, otherwise print that the password is not strong.
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
Use Character.isDigit(c)
Have the user enter a password. The code loops through each character in the string. Add code in the middle section to count how many digits, uppercase and lowercase characters there are. If they have at least one of each, print that their password is ok, otherwise print that the password is not strong.
Your program should prompt the user with the following.
Enter Password:
Below is sample input to test your program.
secret
Your program should output the following
Not Strong
Skeleton:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Password: ");
String password = scan.nextLine();
int upperTotal = 0;
int lowerTotal = 0;
int digitTotal = 0;
for (int i = 0; i < password.length(); ++i) {
char c = password.charAt(i);
// Code to count what character c is here
// Do not print inside of here!
}
// Print the results here
}
}
