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 IfElseExample { public static void main(String[] args) { int number = 3; if (...
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 ...
This code accomplishes the same goal as the double If statements used in the example above, but uses a single statement that executes one of the two statements depending on the value of the user variable. In the case of this example, the output would be “User is 18 or younger.” These...
It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print('Number is negative') Run...

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 ...
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...
