Method Detail isDigit public static boolean isDigit(char c)(Code) Returns true if the specified character is a base-10 digit. isHexDigit public static boolean isHexDigit(char c)(Code) Returns true if the specified character is a base-16 digit. isNumericTypeSpecifier public static boolean isNumericTypeSpecifier(char c, boolean isDecimal)(Code) Returns true if the specified character is a valid type specifier for a numeric value. isOctalDigit public static boolean isOctalDigit(char c)(Code) Returns true if the specific character is a base-8 digit. parseDecimal public static Number parseDecimal(String text)(Code) Builds a Number from the given decimal descriptor. Uses BigDecimal, unless, Double or Float is requested. Parameters:   text - literal text to parse instantiated Number object throws:   NumberFormatException - if the number does not fit within the typerequested by the type specifier suffix (invalid numbers don't makeit here) parseInteger public static Number parseInteger(String text)(Code) Builds a Number from the given integer descriptor. Creates the narrowest type possible, or a specific type, if specified. Parameters:   text - literal text to parse instantiated Number object throws:   NumberFormatException - if the number does not fit within the typerequested by the type specifier suffix (invalid numbers don't makeit here) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
