Java separate the numbers from string

        // string contains numbers
        String str = "The price of the book is $49";
        // extract digits only from strings
        String numberOnly = str.replaceAll("[^0-9]", "");
        // print the digitts
        System.out.println(numberOnly);

Split number java

int num = 5542;
String number = String.valueOf(num);
for(int i = 0; i < number.length(); i++) {
    int j = Character.digit(number.charAt(i), 10);
    System.out.println("digit: " + j);
}
