           4  Long
              •  Represents a 64-bit signed integer.
              •  Methods include: longValue(), floatValue(), doubleValue().

              Task_Long: Here’s an example program demonstrating the use of methods inherited from the Number
              class for the Long class:
              public class LongMethodsExample {
               public static void main(String[] args) {
                   // Example using Long class
                   Long longValue = 123456L;

                   // longValue()
                   long longResult = longValue.longValue();
                   System.out.println(“longValue(): “ + longResult);


                   // floatValue()
                   float floatResult = longValue.floatValue();
                   System.out.println(“floatValue(): “ + floatResult);


                   // doubleValue()
                   double doubleResult = longValue.doubleValue();
                   System.out.println(“doubleValue(): “ + doubleResult);
               }
