| Constructor Summary | |

RandomStringUtils instances should NOT be constructed in
standard programming.

| Method Summary | |
| public static String | random(int count)
| | public static String | random(int count, boolean letters, boolean numbers)
| | public static String | random(int count, int start, int end, boolean letters, boolean numbers)
| | public static String | random(int count, int start, int end, boolean letters, boolean numbers, char[] chars)
Creates a random string based on a variety of options, using
default source of randomness.
This method has exactly the same semantics as
RandomStringUtils.random(int,int,int,boolean,boolean,char[],Random) , but
instead of using an externally supplied source of randomness, it uses
the internal static
Random instance.
Parameters:
count - the length of random string to create
Parameters:
start - the position in set of chars to start at
Parameters:
end - the position in set of chars to end before
Parameters:
letters - only allow letters?
Parameters:
numbers - only allow numbers?
Parameters:
chars - the set of chars to choose randoms from.If null, then it will use the set of all chars. | | public static String | random(int count, int start, int end, boolean letters, boolean numbers, char[] chars, Random random)
Creates a random string based on a variety of options, using
supplied source of randomness.
If start and end are both 0, start and end are set
to ' ' and 'z', the ASCII printable
characters, will be used, unless letters and numbers are both
false, in which case, start and end are set to
0 and Integer.MAX_VALUE.
If set is not null, characters between start and
end are chosen.
This method accepts a user-supplied
Random instance to use as a source of randomness. | | public static String | random(int count, String chars)

| RandomStringUtils | | public RandomStringUtils()(Code) | | RandomStringUtils instances should NOT be constructed in

RandomStringUtils.random(5);.
This constructor is public to permit tools that require a JavaBean instance
to operate.

| random | | public static String random(int count)(Code) | | Creates a random string whose length is the number of characters
specified.
Characters will be chosen from the set of all characters.
Parameters:
count - the length of random string to create the random string |
| random | | public static String random(int count, boolean letters, boolean numbers)(Code) | | Creates a random string whose length is the number of characters
specified.
Characters will be chosen from the set of alpha-numeric
characters as indicated by the arguments.
Parameters:
count - the length of random string to create
Parameters:
letters - if true, generated string will includealphabetic characters
Parameters:
numbers - if true, generated string will includenumeric characters the random string |
| random | | public static String random(int count, int start, int end, boolean letters, boolean numbers)(Code) | | Creates a random string whose length is the number of characters

Characters will be chosen from the set of alpha-numeric
characters as indicated by the arguments.
Parameters:
count - the length of random string to create
Parameters:
start - the position in set of chars to start at
Parameters:
end - the position in set of chars to end before
Parameters:
letters - if true, generated string will includealphabetic characters
Parameters:
numbers - if true, generated string will includenumeric characters the random string |

Parameters:
numbers - only allow numbers?

| random | | public static String random(int count, int start, int end, boolean letters, boolean numbers, char[] chars, Random random)(Code) | | Creates a random string based on a variety of options, using
supplied source of randomness.
If start and end are both 0, start and end are set
to ' ' and 'z', the ASCII printable
characters, will be used, unless letters and numbers are both
false, in which case, start and end are set to
0 and Integer.MAX_VALUE.
If set is not null, characters between start and
end are chosen.
This method accepts a user-supplied
Random instance to use as a source of randomness. By seeding a single
Random instance with a fixed seed and using it for each call,
the same random sequence of strings can be generated repeatedly
and predictably.
Parameters:
count - the length of random string to create
Parameters:
start - the position in set of chars to start at
Parameters:
end - the position in set of chars to end before
Parameters:
letters - only allow letters?
Parameters:
numbers - only allow numbers?
Parameters:
chars - the set of chars to choose randoms from.If null, then it will use the set of all chars.
Parameters:
random - a source of randomness. the random string
throws:
ArrayIndexOutOfBoundsException - if there are not(end - start) + 1 characters in the set array.
throws:
IllegalArgumentException - if count < 0.
