Method Detail

values

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isBlank

public static boolean isBlank(String s)

Return true if this string is either null or just whitespace.

Parameters:

s - the string

Returns:

true if this string is either null or just whitespace.

isNotBlank

public static boolean isNotBlank(String s)

Return true if this string is not null and not just whitespace.

Parameters:

s - the string

Join the collection of objects to a string.

Objects that are null are represented by the empty string.

Parameters:

objects - collection of objects

delimiter - delimiter between the objects

Returns:

joined string

replace

public static String replace(String template,
                             Map<String,String> replacements,

Replace the placeholders in the template with the values in the replacement mapping.

Parameters:

template - template string

replacements - map from key to replacement value

prefix - prefix of the placeholder

suffix - suffix of the placeholder

Returns:

replaced string
