The syntax of the if statement is as follows:
                                                                                                   Start
                 if (< conditional expression >)
                 {
                        [statements]
                                                                                                Conditional     False
                 }
                                                                                                 Expression
                 For example,

                 public class IfStatement                                                              True

                 {                                                                               Body of if
                       public static void main(int num)

                       {
                                                                                                   Stop
                            System.out.println("Entered number is: " + num);

                            if (num % 2 == 0)
                            {

                            System.out.println("The number is even");
                            }

                            System.out.println("Statement outside the if statement");
                       }

                 }
                 Run the  program  twice  for  values of 22 and  7,
                 respectively. When you enter 22, the condition (22 %
                 2 == 0) returns true. So, the statement inside the body
                 of the if statement gets executed and the output will
                 appear as shown:

                 When you enter the value 7, then the output will
                 appear as shown:
                 Since the  condition  (7  % 2 == 0)  returns  false, the
                 statement inside the body of the if statement does
                 not get executed and only the statement outside the
                 if statement gets executed.

                 The if…else Statement


                 The if…else statement helps decide which block
                                                                              Just as the heart repeatedly pumps
                 of  code  to  run.  If the  condition  is true,  the  code
                                                                               blood, iteration in programming
                 inside the if block runs. If the condition is not true,
                                                                               involves repeatedly running a set
                 the code inside the else block runs instead.                           of instructions.
