Assuming the input will always be in the format you provided, you can use String.split() and String.substring() to extract the required information from the input as shown below.

String[] splitName = fullName.split(" ");
String firstName = splitName[0];
String lastName = splitName[1];
String day = bday.split("-")[1];

String username = firstName.substring(0, 2) + lastName.substring(0, 3) + day;
