int count = 0;

count is 0
count is 1
count is 2
count is 3
Done with the loop

Boundary Conditions

What a loop does is affected by three activities. To decide what a loop will do, look carefully at the following:

• Look at the first value.
• Figure out the ending value by looking at the while loop condition.
• Look at what change is made each time.

Look at the following program fragment:

int count = 1;  
while ( count <  4 )           // this is different 
{
  System.out.println( "count is:" + count );
  count = count + 1;   
}
System.out.println( "Done with the loop" );      

Notice the changes from the previous program in the loop condition.
