How An Array Works
When an array is first defined, you must tell the computer system what type of data will be stored & how many memory cells you would like to use. For ex. in the Java programming language, you create a new array and specify the type and the size of the array by using the "new" keyword. you also specify a name for the array, which is used to access the contents of the cells in the array. Consider this statement:

Java example: int[ ] aGrades = new int[5];

-The “int[ ]” part of the statement tells the computer that the array will hold integer (numeric values). If the array was going to hold character values, it would say char[ ].
- The word “aGrades” is the name of the array, the name by which the memory contents will be accessed.
- The “new” keyword tells the computer that a new array is being created.
- The “int[5]” part of the statement tells the computer to reserve five memory locations to store the numeric (int) values for the array.
- The “=” sign (equals sign, called an assignment operator) takes the newly created array of 5 memory cells and assigns aGrades as the “manager” of those memory cells.
- The “;” (semicolon) tells the computer that the end of statement has been reached

can Hashing result in collisions?
yes b/c The same relative key is generated for more than one original key value

One solution: expand the algorithm to add the sum of the digits of the phone number to the relative key
The sum of the digits in phone number 7025551234 is 34
Original key 1045 + 34 gives 1079
Lessens collisions, but does not eliminate them
