                10          if(n>0)
                11              System.out.println(n + " is a positive number.");

                12

              7.2.5 Nested if Statement
              Certain situation demands the if statement within another if statement. The if statement inside another if statement
              is called nested if. The inner if statement will execute only if the outer if statement evaluates to true. If the outer
              if statement does not satisfy, then the else part of the outer if statement will execute. The syntax of the nested if
              statement is:
                  if(Condition 1)
                  {
                      if(Condition 2)
                          Statement 1;
                      else
                          Statement 2;
                  }
