JAVA ARRAY OF OBJECT, as defined by its name, stores an array of objects. Unlike a traditional array that store values like string, integer, Boolean, etc an array of objects stores OBJECTS. The array elements store the location of the reference variables of the object.
Syntax:
Class obj[]= new Class[array_length]
Example: To create Array Of Objects
Step 1) Copy the following code into an editor
class ObjectArray{ public static void main(String args[]){ Account obj[] = new Account[2] ; //obj[0] = new Account(); //obj[1] = new Account(); obj[0].setData(1,2); obj[1].setData(3,4); System.out.println("For Array Element 0"); obj[0].showData(); System.out.println("For Array Element 1"); obj[1].showData(); } } class Account{ int a; int b; public void setData(int c,int d){ a=c; b=d; } public void showData(){ System.out.println("Value of a ="+a); System.out.println("Value of b ="+b); } }
Step 2) Save , Compile & Run the Code.
Step 3) Error=? Try and debug before proceeding to step 4.
Step 4) The line of code, Account obj[] = new Account[2]; exactly creates an array of two reference variables as shown below
Step 5) Uncomment Line # 4 & 5. This step creates objects and assigns them to the reference variable array as shown below. Your code must run now.
Output:
For Array Element 0 Value of a =1 Value of b =2 For Array Element 1 Value of a =3 Value of b =4
