The syntax of the if…else statement is as follows:
Start
if (< conditional expression >)
{
[statements]
}
Conditional False
Body of else
else Expression
{
[statements] True
}
Body of if
For example:
public class IfElseStatement
{
Stop
public static void main(int num)
{ Flowchart of if ....else statement
System.out.println("Entered number is: " + num);
if (num % 2 == 0)
{
System.out.println("The number is even");
}
else
{
System.out.println("The number is odd");
}
System.out.println("Statement outside the if...else statement");
}
}
As you did in the previous example, run the program
twice for the values of 22 and 7, respectively. When
you enter 22, the condition (22 % 2 == 0) returns true.
So, the output will appear as shown:
Output
When you enter the value 7, then the output will
appear as shown:
Because the condition (7% 2 == 0) in the if statement
returns false, control is transferred to the statements
Output in the else block.
