Question mplement the following class diagrams as follows. Note that you CANNOT use any classes in the Collections Frameworks such as ArrayList, LinkedList etc Each class implement the Displayable interface and the display method should display all the current object's and its superclass object's information. Define appropriate parameters properly so that all the objects can be created properly Define appropriate set and get methods if needed in other classes' methods Displayable ants + display0:void + MAX-EMPLOYEES: 1000 : int Company - empld: int #employees : Employee # numEmployees : int salary : double * +Company( + addEmployee(employee) : void +getSalary0:double url: String + getEmployeesHighSalary(double limit) : Employee! /. employees who have salary more than limit

Explanation / Answer

//Defining interface
interface Displayable{
   public void display();
}

//Implementing Employee class

class Employee implements Displayable{
   //declaring the specified instance variables
   int empid;
   double salary;
  
   //defining constructor for Employee class
   Employee(int empid,double salary){
       this.empid=empid;
       this.salary=salary;
   }
   //defining getSalary() method
   double getSalary(){
       return this.salary;
   }
  
   //Implementing method of Displayable Interface
  
   public void display(){
       System.out.println("Employee Id is"+this.empid);
       System.out.println("Employee Salary is "+this.salary);
   }
}

//Implementing CompanyConstants class

class CompanyConstants{
   final int MAX_EMPLOYEES=1000;
}

//Implementing Company class

class Company extends CompanyConstants implements Displayable{
   String compName;
   Employee employees[];
   int numEmployees;
  
   //defining constructor for Company class
  
   Company(String compName,Employee employees[],int numEmployees){
       this.compName=compName;
       this.employees=employees;
       this.numEmployees=numEmployees;
   }
  
   Company(String compName){
       this.compName=compName;
       this.numEmployees=0;
   }  
   //defining addEmployee() method
  
   void addEmployee(Employee employee){
       if(numEmployees>=MAX_EMPLOYEES){
           System.out.println("Maximum Employees reached");
       }
       else{
           this.employees[numEmployees]=employee;
           numEmployees++;
       }
   }
   //defining display method
   public void display(){
       System.out.println("Max employees is "+MAX_EMPLOYEES);
       System.out.println("Company Name:"+this.compName);
       System.out.println("Number of employees:"+this.numEmployees);
       System.out.println("Employees are:");
       for(int i=0;i<this.numEmployees;i++){
           System.out.print("Employee"+i);
           employees[i].display();
       }
   }
  
}

class InternetCompany extends Company{
   String url;
  
   //constructor
   InternetCompany(String url,String compName){
       super(compName);
       this.url=url;
   }
  
   //defining the method to get employees whose salary is above the limit
   Employee[] getEmployeesHighSalary(double limit){
       int current=0;
       Employee aboveLimit[]=new Employee[this.numEmployees];
       for(int i=0;i<this.numEmployees;i++){
           if(this.employees[i].salary>limit){
               aboveLimit[current]=this.employees[i];
               current++;
           }
       }
       return aboveLimit;
   }
}

I edited the code and cleared all the errors,please check it and if you want to perform any operation using this please specify it or define your own class to implement the main method to use all the above classses and functionalities.
