In this example, the condition number > 5 evaluates to true because number is 10. Therefore, the message "The number is greater than 5." is printed to the console.Example 2: if-else Statementpublic class IfElse
Theif-else statementin Java is the most basic of all theflow control statements. Anif-elsestatement tells the program to execute a certain block only if a particular test evaluates totrue, else execute the alternate block if the condition isfalse. Theifandelseare reservedkeywordsin Java, and ...
In the example above, time (22) is greater than 10, so the first condition is false. The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening"....
In the following example, we use a variable in the Boolean expression to execute the statement based on the condition. For example, if a student obtained more than 80% marks, he passes an examination else, he is failed. 在下面的示例中,我们在布尔表达式中使用变量来根据条件执行语句。 例如,如...
Example: R if...else if...else Statement x <- 0 # check if x is positive or negative or zero if (x > 0) { print("x is a positive number") } else if (x < 0) { print("x is a negative number") } else { print("x is zero") } Output [1] "x is zero" In the abov...
if statement and implement the operation. 3. refactoring let’s explore the alternate options to replace the complex if statements above into much simpler and manageable code. 3.1. factory class many times we encounter decision constructs which end up doing the similar operation in each branch. ...
Indentation in PythonPython uses indentation to define a block of code, such as the body of an if statement. For example,x = 1 total = 0 # start of the if statement if x != 0: total += x print(total) # end of the if statement print("This is always executed.") Run Code ...
Another side effect of having nested decision constructs is they become unmanageable. For example, if we need to add a new operator, we have to add a new if statement and implement the operation. 3. Refactoring Let’s explore the alternate options to replace the complex if statements above ...
