Foil 8 Arrays

From Short Introduction to Kids on Basic Programming Concepts in Java Sonia Kovalesky festival workshop (High School Girls) -- October 23 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
