How to check if a string is of a specific pattern [closed]

Answer 1

public static void main(String[] args) throws Exception {
    String id = "TV1523";
    BufferedReader br = new BufferedReader((new InputStreamReader(System.in)));
    String tocompare = br.readLine();
    if(tocompare.equals(id)) { //do stuff

something like that, except you might wand to enclose the readLine() within a try catch instead :x
