Question Details:

Write a program that reads five integers from the keyboard. Each integer is between
1 and 10 (you will need to validate the user’s input; if you reject the user’s
input, you must re-read the input until a valid quantity is entered). For each
input, your program should print a line of dollar signs, of length "x", where x is the
integer value entered. Name the .java file Lab7_Ex1.

Example input/output:

Enter the next number: 7 [enter]
$$$$$$$
Enter the next number: 11 [enter]
That is an invalid number.
Enter the next number: (the program would continue...)

Response Details:

Let us first write a method to print x number of dollar signs.

public static void printDollarSigns(int number)
{
for(int x = 0; x < number; x++)
{
System.out.print('$');
}
System.out.println();
}

Now in our main method, we need to get user input as well as call the printDollarSigns() method for each valid input.

public static void main(String[] args)
{
// open user input
Scanner kb = new Scanner(System.in);

// read user input

// count will store the number of valid inputs
int count = 0;

while(count < 5)
{
// get user input
int input = kb.nextLine();

// check for validity
if(input<1 || input>10)
{
// invalid
System.out.println("That is an invalid number.");
continue;
}
// otherwise the number is valid
else
{
// print dollar signs
printDollarSigns(input);

// increment count
count++;
}
}
}
