Java Create a class Room with data members as length, breadth and height. Calculate area of 10 Rooms and Display the same. Make use of parameterized constructor, default constructor and this keyword. code example

Example: Overload the default constructor to take a parameter for each attribute and set it

class StudentData
{
   private int stuID;
   private String stuName;
   private int stuAge;
   StudentData()
   {
       //Default constructor
       stuID = 100;
       stuName = "New Student";
       stuAge = 18;
   }
   StudentData(int num1, String str, int num2)
   {
       //Parameterized constructor
       stuID = num1;
       stuName = str;
       stuAge = num2;
   }
   //Getter and setter methods
   public int getStuID() {
       return stuID;
   }
   public void setStuID(int stuID) {
       this.stuID = stuID;
   }
   public String getStuName() {
       return stuName;
   }
   public void setStuName(String stuName) {
       this.stuName = stuName;
   }
   public int getStuAge() {
       return stuAge;
   }
   public void setStuAge(int stuAge) {
       this.stuAge = stuAge;
   }

   public static void main(String args[])
   {
       //This object creation would call the default constructor
       StudentData myobj = new StudentData();
       System.out.println("Student Name is: "+myobj.getStuName());
       System.out.println("Student Age is: "+myobj.getStuAge());
       System.out.println("Student ID is: "+myobj.getStuID());

       /*This object creation would call the parameterized
        * constructor StudentData(int, String, int)*/
       StudentData myobj2 = new StudentData(555, "Chaitanya", 25);
       System.out.println("Student Name is: "+myobj2.getStuName());
       System.out.println("Student Age is: "+myobj2.getStuAge());
       System.out.println("Student ID is: "+myobj2.getStuID()); 
  }
}
