Answer 1

The complete program source code for testing including all parts is given below:

class Child
{
//private data member
String name;
int age;
  
//default constructor
Child()
{
  
}
  
//parameterize constructor
Child(String nm, int ag)
{
name = nm;
age = ag;
}
  
//method to set name
public void setName(String nm)
{
name = nm;
}
  
//method to set age
public void setAge(int ag)
{
age = ag;
}
  
//method to get age
public int getAge()
{
return age;
}
  
//method to get name
public String getName()
{
return name;
}
  
//method to return description about child
public String toString()
{
return "Child description: \nName: "+name+"\nAge: "+age;
}
}

public class Main
{
   public static void main(String[] args)
   {
   //create object
       Child c = new Child("ABC", 17);
      
       //display output
       System.out.println(c);
   }
}

OUTPUT:
