Здравей, колега.

В този scope, където печаташ, просто сложи %n, след като е свършил, реда.
Друга грешка не виждам.

}
    balance += amount;
    System.out.printf("Increase: %.2f%n", amount);
    input = scanner.nextLine();
}

Това е кодът ми. Взимам 100 те то4ки, но не разбирам ред 5. Защо трябва да подам вътре в Whil-a: Double.parseDouble(input), а не Double.parseDouble(scanner.nextLine()). Нали са едно и също нещо???

String input = scanner.nextLine();
double sum = 0.0;
while (!input.equals("NoMoreMoney")) {
double currentNum = Double.parseDouble(input); // not (scanner.nextLine()) !!! ???
if (currentNum < 0) {
System.out.println("Invalid operation!");
break;
}
System.out.printf("Increase: %.2f%n", currentNum);
sum += currentNum;
input = scanner.nextLine();
}
System.out.printf("Total: %.2f", sum);
