create an object of a class that contains an array in java code example

Example 1: creating array of objects in java

class Main{
   public static void main(String args[]){
     //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();
 }
}

Example 2: java class array of objects

public class MainClass
{  
    public static void main(String args[])
    {
        System.out.println("Hello, World!");
        //step1 : first create array of 10 elements that holds object addresses.
        Emp[] employees = new Emp[10];
        //step2 : now create objects in a loop.
        for(int i=0; i<employees.length; i++){
            employees[i] = new Emp(i+1);//this will call constructor.
        }
    }
}

class Emp{
    int eno;
    public Emp(int no){
        eno = no;
        System.out.println("emp constructor called..eno is.."+eno);
    }
}
