CodePudding user response：

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;

CodePudding user response：

String[] firstLastName = fullname.split(" ");

System.out.println("Enter Username: "   firstLastName[0].substring(0, 2)   firstLastName[1].substring(0, 3)   bday.split("-")[1]);
