Foil 9 Arrays

From Computing and Java Language Basics NPAC Java Academy February--April 99 -- Feb 13 1999. by Nancy McCracken
Sometimes you have a collection of values that you want to give one name. One way to do that in Java is to have an array.
To create an array like this, you must say what type the elements are (they must all be the same type) and how many there will be:
An array has a set of positions to store values. Each position is given an index number:
int numbers [ ] = new int [ 7 ] ;
String labels [ ] = new String [ 64 ] ;
0 1 2 3 4 5 6
