1. Arrays of Objects // The following does NOT create memory for
// objects, it only makes a blueprint array
Employee [] employees = new Employee [MAXEMP];
// Must create memory and call constructor for
// each single member of aray of objects
for (i = 0; i < MAXEMP; i++)
employees[i] = new Employee();

2. Passing Arrays to Methods
Pass Array Name into Method
int [] intArray = new int[100];
loadArray(intArray);
Accept into Method as an Array with No Set Size
void loadArray( int [] passedArray )
Changes to Array in Method *will* Update Original Array

3. public static void main(String [] args){
final int ASIZE = 5;
int [] intArray= new int[ASIZE];
for(int i = 0; i < ASIZE; i++)
intArray[i] = i;
System.out.println( intArray[0]);
changeZero(intArray); }
static void changeZero(int [] passedArray)
passedArray[0] = 1000;

4. Initializing Arrays char [] cArray3 = {'a', 'b', 'c'};
int [] iArray = {1, 2, 3, 4};
double [] dArray = {3.4, 5.67e4};

5. Two Dimensional Arrays
char [][] cArray = new char[10][20];
int [][] iArray = new int[100][50];
cArray[0][0] = ‘a’;
cArray[0][1] = ‘b’;
cArray[9][19] = ‘x’;
iArray[0][0] = 99;
iArray[1][5] = 135;
iArray[99][49] = 0;

6. Employee Class Review Create a Class Employee Employee.java
Employee Attributes (data members)
Constructor
Accessor Methods
Mutator Methods
tryEmployee.java (Client Test Program)
