Test the Baby class below by writing a client program which uses an array to store information about 4 babies. That is, each of the four elements of the array must store a Baby object. If you have an array for baby names and another array for baby ages, then you have missed the point of the exercise and therefore not met the requirement of this exercise. A Baby class object stores the required information about a Baby. So each Baby object will have its own relevant information, and thus each object must be stored in one element of the array. The client program should: a. Enter details for each baby (name and age) and thus populate the Baby array b. Output the details of each baby from the array (name and age) c. Calculate and display the average age of all babies in the array d. Determine whether any two babies in the array are the same As the required information for these tasks is stored in the Baby array, you will need to use a loop to access each array element (and use the dot notation to access the appropriate set and get methods to assign/retrieve the information). For part d above, a nested loop is required. import java.util.Scanner; public class Baby { private String name; private int age; //default constructor public Baby(){ name="abc"; age=3; } //second constructor taking two //parameters, a string to set the name and an integer to set the age public Baby(String name,int age){ this.name=name; this.age=age; } // Setter Method public void setName(String newName) { if(newName != null && !newName.matches(" ")){ name = newName; } } // Getter Method public String getName() { return name; } public void setAge(int newAge){ if(newAge>=1 && newAge<=4){ age=newAge; } } public int getAge(){ return age; } public void isEquals(){ Baby baby1= new Baby("hello",2); Baby baby2= new Baby("hello",2); boolean bool = (baby1.name).equals(baby2.name); System.out.println(bool); } } class MyClass{ //start of main function public static void main(String[] args) { Baby myObj = new Baby(); Scanner scanner=new Scanner(System.in); System.out.println("Enter Name :"); String string1 =scanner.nextLine(); myObj.setName(string1); System.out.println("Enter Age :"); int age= scanner.nextInt(); myObj.setAge(age); Baby myObj1 = new Baby(myObj.getName(),myObj.getAge()); System.out.println("Name is : "+myObj1.getName()); System.out.println("Age is : "+myObj1.getAge()); myObj.isEquals(); }//end of the main function }
Test the Baby class below by writing a client program which uses an array to store
information about 4 babies. That is, each of the four elements of the array
must store a Baby object.
If you have an array for baby names and another array for baby ages,
then you have missed the point of the exercise and therefore not met
the requirement of this exercise.
A Baby class object stores the required information about a Baby. So
each Baby object will have its own relevant information, and thus each
object must be stored in one element of the array.
The client program should:
a. Enter details for each baby (name and age) and thus populate the
Baby array
b. Output the details of each baby from the array (name and age)
c. Calculate and display the average age of all babies in the array
d. Determine whether any two babies in the array are the same
As the required information for these tasks is stored in the Baby array, you
will need to use a loop to access each array element (and use the dot notation
to access the appropriate set and get methods to assign/retrieve the
information).
For part d above, a nested loop is required.
import java.util.Scanner;
public class Baby {
private String name;
private int age;
//default constructor
public Baby(){
name="abc";
age=3;
}
//second constructor taking two
//parameters, a string to set the name and an integer to set the age
public Baby(String name,int age){
this.name=name;
this.age=age;
}
// Setter Method
public void setName(String newName) {
if(newName != null && !newName.matches(" ")){

// Getter Method
public String getName() {
return name;

public void setAge(int newAge){
if(newAge>=1 && newAge<=4){

}
public int getAge(){
return age;
}
public void isEquals(){
Baby baby1= new Baby("hello",2);
Baby baby2= new Baby("hello",2);
boolean bool = (baby1.name).equals(baby2.name);
System.out.println(bool);
}
}
class MyClass{
//start of main function
public static void main(String[] args) {
Baby myObj = new Baby();
Scanner scanner=new Scanner(System.in);
System.out.println("Enter Name :");
String string1 =scanner.nextLine();
myObj.setName(string1);
System.out.println("Enter Age :");
int age= scanner.nextInt();
myObj.setAge(age);
Baby myObj1 = new Baby(myObj.getName(),myObj.getAge());
System.out.println("Name is : "+myObj1.getName());
System.out.println("Age is : "+myObj1.getAge());
myObj.isEquals();
}//end of the main function
