Which of these methods is not defined in both Byte and Short wrappers?intValue()isInfinite()toString()hashCode()

To determine which method is not defined in both the Byte and Short wrapper classes in Java, let's analyze each method:

1. intValue(): This method is defined in both Byte and Short classes. It converts the respective wrapper type to an int.

2. isInfinite(): This method is specific to floating-point number types (Float and Double) and is not defined in either Byte or Short classes.

3. toString(): This method is defined in both wrapper classes. It returns a string representation of the respective wrapper type.

4. hashCode(): This method is overridden in both Byte and Short to provide a hash code value for the respective wrapper objects.

Conclusion

The method that is not defined in both Byte and Short wrappers is isInfinite().
