How to split the string into string and integer in java?

Question

I have the String a="abcd1234" and I want to split this into String b="abcd" and Int c=1234. This Split code should apply for all king of input like ab123456 and acff432 and so on. How to split this kind of Strings. Is it possible?

Answer 1

You could try to split on a regular expression like (?<=\D)(?=\d). Try this one:

String str = "abcd1234";
String[] part = str.split("(?<=\\D)(?=\\d)");
System.out.println(part[0]);
System.out.println(part[1]);

will output

abcd
1234

You might parse the digit String to Integer with Integer.parseInt(part[1]).

Answer 2

String st = "abcd1234";
String st1=st.replaceAll("[^A-Za-z]", "");
String st2=st.replaceAll("[^0-9]", "");
System.out.println("String b = "+st1);
System.out.println("Int c = "+st2);

Output

String b = abcd
Int c = 1234
