Method Detail

countCharback to summary
public static long countChar(String text, char c)
isEmptyback to summary
public static boolean isEmpty(final CharSequence cs)

Copied from Apache commons-lang3-3.6

Checks if a CharSequence is empty ("") or null.

StringUtils.isEmpty(null)      = true
StringUtils.isEmpty("")        = true
StringUtils.isEmpty(" ")       = false
StringUtils.isEmpty("bob")     = false
StringUtils.isEmpty("  bob  ") = false

Note

This method changed in Lang version 2.0. It no longer trims the CharSequence. That functionality is available in isBlank().

Parameters
cs:CharSequence

the CharSequence to check, may be null

Returns:boolean

true if the CharSequence is empty or null

isLengthOddback to summary
private static boolean isLengthOdd(String str)

public static boolean matches(String text, Pattern pattern)
removeCRback to summary
public static String removeCR(String text)
replaceback to summary
public static String replace(final String text, String searchString, final String replacement)

The modified implementation is based on StringUtils#replace(String text, String searchString, String replacement, int max), Apache commons-lang3-3.6

Replaces all occurrences of a String within another String.

A null reference passed to this method is a no-op.

StringUtils.replace(null, *, *)        = null
StringUtils.replace("", *, *)          = ""
StringUtils.replace("any", null, *)    = "any"
StringUtils.replace("any", *, null)    = "any"
StringUtils.replace("any", "", *)      = "any"
StringUtils.replace("aba", "a", null)  = "aba"
StringUtils.replace("aba", "a", "")    = "b"
StringUtils.replace("aba", "a", "z")   = "zbz"
Parameters
text:String

text to search and replace in, may be null

searchString:String

the String to search for, may be null

replacement:String

the String to replace it with, may be null

Returns:String

the text with any replacements processed, null if null String input
