Inside the code block, theSystem.out.println("x is " + x--);statement on line 3 prints the current value ofxusing theprintln()method. (For more on theSystem.out.printlnstatement, check out our tutorialHow To Write Your First Program in Java.) Inside the argument forprintln(),xis post...
The indentation under the if and else statements is for human readers. The C# language doesn't treat indentation or white space as significant. The statement following the if or else keyword executes based on the condition. All the samples in this tutorial follow a common practice to...
Let’s take a look at how this all works in practice using an example. We’ll create a range() object that represents the consecutive numbers from 21 to 23. Then we’ll create an iterator with the iter() function and return successive elements with the next() function. The exception wi...
I don't think it's a good idea to randomly place closing braces at the end of code lines. This practice is generally discouraged by style guides because it can disrupt the code's flow for many readers. How to Access an Iteration Counter in a For Each Loop, Java's for each loop does...
They are rarely used in practice, however. for (int i = 1; i < 100; System.out.println(i++)); for (int i = 0, j = 0; (i + j < 10); i++, j++) { // Do something } 2010-11-4 Introduction to Java Programming Chapter 4 - 14 Note If the loop-continuation-condition ...

The action-after-each-iteration in a for loop can be a list of zero or more comma-separated statements. Therefore, the following two for loops are correct. They are rarely used in practice, however. for (int i = 1; i < 100; System.out.println(i++));...
