replace

public static String replace(String text,
 String searchString,
 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 - text to search and replace in, may be null

searchString - the String to search for, may be null

replacement - the String to replace it with, may be null

Returns:

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

isEmpty

public static boolean isEmpty(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 - the CharSequence to check, may be null

Returns:

true if the CharSequence is empty or null
