Example: creating array of objects in java

     //create array of employee object  
    Employee[] obj = new Employee[2] ;
 
     //create & initialize actual employee objects using constructor
     obj[0] = new Employee(100,"ABC");
     obj[1] = new Employee(200,"XYZ");
 
     //display the employee object data
     System.out.println("Employee Object 1:");
     obj[0].showData();
     System.out.println("Employee Object 2:");
     obj[1].showData();
  }
}
//Employee class with empId and name as attributes
class Employee{
  int empId;
  String name;
  //Employee class constructor
  Employee(inteid, String n){
     empId = eid;
     name = n;
  }
public void showData(){
   System.out.print("EmpId = "+empId + "  " + " Employee Name = "+name);
   System.out.println();
 }
