The second condition goes between these new round brackets. Next comes else if, followed by a pair of round brackets. They fall under the control statements category since they let you control the order of execution based on a logic you specify.

In this case, the action is to simply print an error message stating that the bicycle has already stopped. In this case, the action is to simply print an error message stating that the bicycle has already stopped. An if statement can include an else clause that executes a statement or block if the boolean expression is not true.

if, else and switch in Java : nesting of if else, switch, conditions

One of my readers is in trouble and has a quiz on if else statements java topic, so I thought I would try my best to help him as well as everyone out by posting another Java tutorial today. But were you aware that you could nest these if statements inside of each other. How about I first introduce a simple example to refresh your memory. So, you see here how I made use of a nested if statement. Since my age variable is still set as 29, the code will flow to the first if and check to see if the age is less than 13. We all know that 29 is not less than 13, so we continue downward to the first else if. Well, the same rules always apply to the flow of code in an if. If the none of the conditions evaluate to true in all the if conditions, then the code will automatically choose the else path if it exists. In our example, it does indeed exist. So the code will choose that path. So, as predictable as the sun will rise and set, Java will follow the same set of rules for this new if. We will now evaluate if age is less than 65. And as luck would have it, our variable is set to 29. Where does the code flow from here. You have to consider the fact that you are now inside of nested if statements and make note of where the beginning and end of all of those curly braces are. Allow me to re-write the code block with some comments that may help you visualize where the code will flow. So instead it will skip if else statements java the else block. And what do we see after the inner else block. Yet another console output line. Remember to follow through those curly braces to know exactly where you are. The code then exits the outer else code block and the program will terminate. Want Free Access to my Best Java Courses. Go ahead an click the button below to get started. I show you how the code flows in the debugger. I hope that helps out my reader for his quiz tomorrow, and I look forward to hearing that he aced it!.

If that is the case, then x will be the greatest number, otherwise not. Within the curly brackets, the first statement i. It can be used as java if-else short-hand. The compiler cannot catch this sort of error; you'll just get the wrong results. If the condition evaluates to true, statement-1 is executed. For example, the ticket program might have several discounts. The general form of a nested if statement is this: if expression-1 if expression-2 statement-1 else statement-2 else if expression-3 statement-3 else statement-4 In this example, expression-1 is the first to be evaluated. Then break statement will terminate the loop without checking the rest of the cases.
