Question

Answer 1

Pattern pattern= Pattern.compile("^pwe01 \\| 0 \\| 1 \\| DPS-1200AB-4(D| D|W)$");

System.out.println(pattern.matcher("pwe01 | 0 | 1 | DPS-1200AB-4D").find());//FALSE
System.out.println(pattern.matcher("pwe01 | 0 | 1 | DPS-1200AB-4 D").find());//TRUE
System.out.println(pattern.matcher("pwe01 | 0 | 1 | DPS-1200AB-4W").find());//TRUE
System.out.println(pattern.matcher("pwe01 | 0 | 1 | DPS-1200AB-4 W").find());//FALSE
