Question

Let’s say I have a string “-1 2”
Is there a “reverse string.format” where I can grab those ints like

Integer first = new Integer();
Integer second = new Integer();
String.grab("%d %d", first, second);
print(first + " " second); // prints "-1 2"

Answer 1

You could split your input by spaces, then call Integer.parseInt on each string:

String input = "-1 2 -4 6 8";
String[] numberStringArray = input.split(" ");

for (String s : numberStringArray) {
    int n = Integer.parseInt(s);
    System.out.println("n = " + n);
}

NOTE: this does ZERO error checking
