Question

can someone help explain this for me?

In the class we discussed the class Account, suppose we have a constructor accepting one number as the parameter to indicate the initial balance for the Account object. What does the computer do when it executes the following statements? What are the differences between the two statements? Try to give as complete an answer as possible. Account[] accl= new Account[30]; Account acc2-new Account (30);

Answer 1

Account[] acc1 = new Account[30]; //The computer creates an array of object named as acc1

Account acc2 = new Account(30);     //The computer will create an object named as acc2

Difference between the two statements are as follows:

1st statement: It executes it the following manner->

acc1[0] = new Account();   acc1[1] = new Account();.................................................acc1[29] = new Account();

It creates an array of object of length size = 30 (0 to 29)

2nd statement: It executes it the following manner->

Account constructor is used to give acc2 an initial balance of 30.
