How do I break the loop in Java with a letter instead of a number? I want it to be "Press X to exit".This is my code below.
System.out.println("Average Demo using do Loop");
System.out.println();
System.out.println("Calculates an average of all numbers: Enter 'X' when finished");
do {
System.out.print("Enter number ");
input = scnr.nextInt();
sum = sum + input;
count++;
}
while (input != 1);
avg = sum / (count - 1);
System.out.println("The average of all numbers is " + avg);
System.out.println();
System.out.println();
count = 0;
input = 0;
avg = 0;
sum = 0;
System.out.println("Average Demo using a While Loop");
System.out.println();
System.out.println("Calculates an average of all numbers: Enter 'X' when finished");
// end of do...while loop
while (input != 1)
{
System.out.print("Enter number ");
input = scnr.nextInt();
sum = sum + input;
count ++;
}
avg = sum / (count - 1);
System.out.println("The average of all numbers is " + avg);
System.out.println();
//end of while loop
for (int i = 0; i < 10; i++)
{
for (int y = 0; y <= i; y++)
{
System.out.print("*");
}
System.out.println();
//end of for loop
}
You'll have to use scanner.nextLine() to get the input as a string first, as using scanner.nextInt() for character will cause an exception.
do {
System.out.print("Enter number ");
string input = scnr.nextLine();
if(input.equals("x") || input.equals("X") ) {
break;
else {
int num = Integer.parseInt(input);
sum = sum + num;
count++;
}
} while ( ! input.toUpperCase.equals("X") );
