Example Program For An Array Of Objects In Java The example program that we have given below shows a member function of the Employee class that is used to assign the initial values to the Employee objects. ("EmpId = "+empId + " " + " Employee Name = "+name) Employee class with empId and name as attributes create & initialize actual employee objects using constructor The output of the program shows the contents of each object that was initialized previously. Then we pass initial values to each of the objects using the constructor. In the main function, after an array of employees is created, we go ahead and create individual objects of the class employee. The class has a constructor that takes in two parameters i.e.
The following program shows the initialization of array objects using the constructor. You can also have a separate member method in a class that will assign data to the objects. When you create actual objects, you can assign initial values to each of the objects by passing values to the constructor. One way to initialize the array of objects is by using the constructors. Thus, once the array of objects is declared and instantiated, you have to create actual objects of the class. We already discussed that an array of objects contains references to the actual class objects. In the case of an array of objects, each element of array i.e. As the array of objects is different from an array of primitive types, you cannot initialize the array in the way you do with primitive types. Once the array of objects is instantiated, you have to initialize it with values. The above statement will create an array of objects ‘empObjects’ with 2 elements/object references. Note that once an array of objects is instantiated like above, the individual elements of the array of objects need to be created using new. You can declare and instantiate the array of objects as shown below: Employee empObjects = new Employee The declarations of the array of objects above will need to be instantiated using ‘new’ before being used in the program. So, if you have a class ‘Employee’ then you can create an array of Employee objects as given below: Employee empObjects Class_name objArray Īlternatively, you can also declare an Array of Objects as shown below: Class_nameobjArray īoth the above declarations imply that objArray is an array of objects. The following statement creates an Array of Objects.
