Hello, how can I add more than one number in the console using a scanner by writing one line code?

Answer 1

you can use a loop to repeatedly prompt the user for a number and add it to a running total. Here is an example of how you could do this in one line of code:

int sum = 0;
while (scanner.hasNextInt()) {
sum += scanner.nextInt();
}

You can also use a for loop to achieve the same result:

int sum = 0;
for (int i = 0; scanner.hasNextInt(); i++) {
sum += scanner.nextInt();
}
