Print EAN 128 In Java
Using Barcode generator for Java Control to generate, create UCC.EAN - 128 image in Java applications.
Nested if structures aren t all that difficult, but they can be messy, especially as you get several layers deep (as you will, eventually) The following tips help make sure that everything makes sense: Watch your indentation Be vigilant on your indentation scheme An editor like Aptana, which automatically indents your code, is a big plus Indentation is a great way to tell what level of code you re on Use comments You can easily get lost in the logic of a nested condition Add comments liberally so that you can remind yourself where you are in the logic Note that I specify which if statement is ending Test your code Just because you think it works doesn t mean it will Surprises will happen Test thoroughly to make sure that the code does what you think it should do

for loops are based on an integer, which is sometimes called a sentry variable In this example, lap serves as the sentry variable You typically use the sentry variable to count the number of repetitions through a loop The for statement has three distinct parts: Initialization: This segment (lap = 1) sets up the initial value of the sentry Condition: The condition (lap <= 10) is an ordinary condition (although it doesn t require parentheses in this context) As long as the condition is evaluated as true, the loop will repeat Modification: The last part of the for structure (lap++) indicates how the sentry will be modified throughout the loop In this case, I add 1 to the lap variable each time through the loop The for structure has a pair of braces containing the code that will be repeated As usual, all code inside this structure is indented You can have as much code inside a loop as you want The lap++ operator is a special shortcut Adding 1 to a variable is common, so the lap++ operation means add 1 to lap You can also write lap = lap + 1, but lap++ sounds so much cooler When programmers decided to improve on the C language, they called the new language C++ Get it It s one better than C! Those computer scientists are such a wacky bunch! When you know how many times something should happen, for loops are pretty useful
