into following programm:

1.

ublic class DanceClass {

private int age;

/**

* The constructor accepts an argument * for the age field.

*/

public DanceClass(int age) {

this.age = age;

}

public void setAge(int age) {

this.age = age;

}

public int getAge() {

return age;

}

public String getDanceClass() {

String danceClass;

Level level = Level.valueOf("AGE"+age);

if (age == 3)

danceClass = "Level: "+level.showLevel(age)+" Dance Type: "+DanceType.TAPBALLET+" Time: "+"Saturday 10am";

else if(age == 4) danceClass = "Level: "+level.showLevel(age)+" Dance Type: "+DanceType.TAPBALLET+" Time: "+"Saturday 10:30am";

else if(age == 5) danceClass = "Level: "+level.showLevel(age)+" Dance Type: "+DanceType.HIPHOP+" Time: "+"Saturday 11:30am";

else if(age == 6) danceClass = "Level: "+level.showLevel(age)+" Dance Type: "+DanceType.JAZZ+" Time: "+"Saturday 12:30am";

else danceClass = "class is not available";

return danceClass;

}

}

2.

public enum DanceType {

TAPBALLET,

HIPHOP,

JAZZ;

}

3

public enum Level { AGE3(3),AGE4(4),AGE5(5),AGE6(6); private String level; int age; Level(int age){ age = age; } String showLevel(int age){ if(age>2 && age < 5) level = "BEGINNER"; else  level = "INTERMEDIATE"; return level; } }

4.

public class UserRegistrationForm {

private String name;

private String address;

private String phoneNumber;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public String getPhoneNumber() {

return phoneNumber;

}

public void setPhoneNumber(String phoneNumber) {

this.phoneNumber = phoneNumber;

}

}

5.

import java.util.Scanner;

public class danceClassResults {

public static void main(String[] args) {

int age;

// To hold a age of a student String danceClass;

// to hold schedule for the class

// Create a Scanner object to read input.

Scanner keyboard = new Scanner(System.in);

//Get user registration details for the kid

UserRegistrationForm newUser = new UserRegistrationForm();

System.out.println("Please provide your information.");

System.out.println("Name:");

newUser.setName(keyboard.nextLine());

System.out.println("Address:");

newUser.setAddress(keyboard.nextLine());

System.out.println("PhoneNumber:");

newUser.setPhoneNumber(keyboard.nextLine());

// Get age

System.out.println("Enter child's age and " + "I will tell you the schedule: ");

age = keyboard.nextInt();

// Create a danceclass object .

DanceClass test = new DanceClass(age);

// Get the dance class.

String danceClass = test.getDanceClass();

// Display the class.

System.out.print("Available class is " + danceClass);

}

}
