Parameters:

num - A long that specifies the value of the new MLong object.

MLong

public MLong(java.lang.String s)
      throws java.lang.NumberFormatException

Constructs an MLong object and sets it according to the value specified in the String parameter, s. (The Long object's parseLong method is used to convert the string to a numeric value.)

Parameters:

s - A String that specifies the value of the new MLong object.

Throws:

java.lang.NumberFormatException - If s does not contain a String that can be successfully converted to a long value.

Method Detail

Returns the value of this MLong object as a long.

Returns:

A long that has the numeric value represented by this MLong object.

toString

public java.lang.String toString()

Returns a String representation of this MLong object's value. (The Long object's toString method is used to convert the object's value to a String.)
