how to store more than string variable input in one string from loop (JAVA)

I am semi-beginner in java

This is my code

        while (true) {
        System.out.println("Choose the number");
        System.out.println("1");
        System.out.println("2");
        System.out.println("3");
        System.out.println("4 for Display summary and Exit");

        int cho = input.nextInt();

        System.out.println("Registration");

        System.out.println("Enter your full name (first and lastname)");
        String name = input.next();

        System.out.println("Enter your National ID");
        int id = input.nextInt();

        System.out.println("Enter your phone number");
        int phone = input.nextInt();

I made if statement for all the choices 1,2,3,4

And this is number 4 if statement

            else if (cho == 4) {
            System.out.println("Summary");
        }

I want in this loop if user Choice 4 in the main menu prints a summary of all registered users (name, phone, id) that choices 1,2,3, even if the user made more than one register, and then exits the program.
