Everything you need has been explained to you several times already. I don't see how regurgitating the same knowledge again will make any difference.

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

Suppose you want to create an array of <type> with size 1555.
<type> can stand for int, double, or String

The syntax is:

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
<type>[] nameOfTheArray = new <type>[1555];
<type>[] nameOfTheArray = new <type>[1555];

This creates the 1555 empty slots. The actual contents depends on the type.

For example: an int array always starts with all 0's, a boolean array always starts with all false, a String arrray starts with all null. More generally, any Object array starts with all null.

//To make a CD object array of size 1555 write:
CD[] nameOfTheArray = new CD[1555];
 
//Then you must fill this array with some objects (right now its all null).
for(int i =0; i < nameOfTheArray.length; i++)
{
	//put a new CD object at position i
	nameOfTheArray[i] = new CD();
}
//To make a CD object array of size 1555 write:
CD[] nameOfTheArray = new CD[1555];

//Then you must fill this array with some objects (right now its all null).
for(int i =0; i < nameOfTheArray.length; i++)
{
	//put a new CD object at position i
	nameOfTheArray[i] = new CD();
}
