Splitting input

Question

HI CAN SOMEONE TEACH ME HOW TO SPLIT AN INPUT .EXAMPLE IF I INPUT "A1B2C3D4" THE OUTPUT WOULD BE "LETTERS:ABCD" AND "NUMBERS:1234"

Answer 1

you can learn regex for it & then try it, here is code for it:

String text=new Scanner(System.in).nextLine();

//splitting by 1 or more digits, '+' is one or more quantifier
String letters[]= text.split("\\d+");
for(String a:letters)
System.out.print(a);

System.out.println();

//splitting by 1 or more non-digits
String digits[]=text.split("\\D+");
for(String b:digits)
System.out.print(b);

Answer 2

//this ways pretty simple, although I’m sure someone can do much better :)

Scanner scan = new Scanner(System.in);
String input = scan.nextLine();

String nums = "";
String lets = "";

for(String s : input.split("")) {
if(s.matches("[0-9]*"))
nums += s;
else if(s.matches("[a-zA-Z]*"))
lets += s;
}
System.out.printf("NUMBERS: %s\nLETTERS: %s",nums,lets);
