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 string into int array
String[] strArray = input.split(",");
int[] intArray = new int[strArray.length];
for(int i = 0; i < strArray.length; i++) {
intArray[i] = Integer.parseInt(strArray[i]);
