public final class Validate

extends java.lang.Object

Implementation of a Regular Expression parser. This class exposes a series of static methods for String validation.

Method Summary

static boolean	isDate(java.lang.String dateString, java.lang.String dateFormat) Eg.
static boolean	isDecimal(java.lang.String numberString) Eg.
static boolean	isInteger(java.lang.String numberString) Eg.
static boolean	isNegativeDecimal(java.lang.String numberString) Eg.
static boolean	isNegativeInteger(java.lang.String numberString) Eg.
static boolean	isPositiveDecimal(java.lang.String numberString) Eg.
static boolean	isPositiveInteger(java.lang.String numberString) Eg.
static java.lang.String	randomNumberString(int strLength) Deprecated. This should be in another utility class Eg. randomNumberString(5) returns a random number (string) between 10000 and 99999.

Method Detail

isNegativeInteger

public static final boolean isNegativeInteger(java.lang.String numberString)

Eg. isNegativeInteger(numberString) returns true iff :
01) numberString is a whole number (ie. only contains digits) preceded by a negative sign

isPositiveInteger

public static final boolean isPositiveInteger(java.lang.String numberString)

Eg. isPositiveInteger(numberString) returns true iff :
01) numberString is a whole number (ie. only contains digits) >= 0

isInteger

public static final boolean isInteger(java.lang.String numberString)

Eg. isNumber(numberString) returns true iff :
01) numberString is a whole number (ie. only contains digits) optionally prefixed by a negative sign

isNegativeDecimal

public static final boolean isNegativeDecimal(java.lang.String numberString)

Eg. isNegativeDecimal(numberString) returns true iff :
01) numberString is a valid number (with/without a fraction) part, prefixed by a negative sign

isPositiveDecimal

public static final boolean isPositiveDecimal(java.lang.String numberString)

Eg. isPositiveDecimal(numberString) returns true iff :
01) numberString is a positive valid number (with/without a fraction) part, >= 0

isDecimal

public static final boolean isDecimal(java.lang.String numberString)

Eg. isDecimal(numberString) returns true iff :
01) numberString is a valid number (with/without a fraction) part, >= 0

isDate

public static final boolean isDate(java.lang.String dateString,
                                   java.lang.String dateFormat)

Eg. isDate(dateString, dateFormat) returns true iff :
01) dateString is a valid date that is represented in the form of dateFormat
02) dateFormat is as specified in JavaDoc for the class java.text.SimpleDateFormat
Eg. US Date Format --> MM/dd/yy

regularExpression

public static final boolean regularExpression(java.lang.String input,
                                              java.lang.String regularExpression)

Eg. RE(input, regularExpression) returns true iff :
01) input exactly matches the format specified by regularExpression.

randomNumberString

public static final java.lang.String randomNumberString(int strLength)

Deprecated. This should be in another utility class Eg. randomNumberString(5) returns a random number (string) between 10000 and 99999.
