Defining and initializing variables
int counter;
String customerLastName;
int loopLimit = 5;
MyClass myObjectTwo = new MyClass( );
float myVariable = 7.2;
CustomerName myNameVariable = new CustomerName("Sharon Hoffman");
Manipulating variables
counter = 0;
customerLastName = new String("Last");
customerLastName = new String(lastName);
displayName = (displayName + " " + customerMiddleInitial +
« . « );
Arithmetic operations
counter = (counter +1);
nextCustomerNumber = (nextCustomerNumber +1);
outputPremium = (inputPremium * 2);
Logical comparisons
(counter <= loopLimit)
(counter == 0)
(!customerMiddleInitial.equals(" "))
Looping (do...while)
do
{
/*
* do while loop processing goes here
*/
}
while(i < 8);
Looping (for)
for(int x = 0; x<5; x= (x+1))
{
/*
* for loop processing goes here
*/
}
Branching
if (!customerMiddleInitial.equals(" "))
{
displayName.append(" ").append(customerMiddleInitial).append(". ");
}
else
{
displayName.append(" ");
}
Input
InputStreamReader myInput = new InputStreamReader(System.in);
BufferedReader myBuffer = new BufferedReader(myInput);
String myInputString = new String();
try
{
myInputString = (myBuffer.readLine());
}
catch(IOException exc)
{
/*
* error handling goes here
*/
}
Output
System.out.println("Hello World");
