public final class StringUtils extends Object
The StringUtils class provides static methods that helps make string manipulation easy. The primary functionality it is meant to provide is the ability to split a string into a string array based on a given delimiter. This functionality is meant to take the place of the split(String) and split(String, int) method that was introduced in J2SE-1.4. Please note, however, that the splitting performed by this class simply splits the string based on the delimiter and does not perform any regular expression matching like the split methods provided in J2SE-1.4.

Method Detail
-
contains
public static boolean contains(String string, String target)
Returns whether the first parameter contains the second parameter.- Parameters:
string
- must not be.
target
- must not benull.
- Returns:
- true if the target is contained within the string.
-
replaceAll
public static String replaceAll(String string, String target, String replace)
Returns the string resulting from replacing all occurrences of the target with the replace string. Note that the target matches literally, and this is not the same behavior as the String.replaceAll, which uses regular expressions for doing the matching.- Parameters:
string
- the start string. Must not benull
.target
- the target to search for in the start string. Must not benull
.replace
- the replacement string to substitute when the target is found. Must not benull
.- Returns:
- String result. Will not be
null
. If target is not found in the given string, then the result will be the entire input string.
-
replaceAllIgnoreCase
public static String replaceAllIgnoreCase(String string, String target, String replace)
Returns the string resulting from replacing all occurrences of the target with the replace string. Note that the target matches literally but ignoring the case, and this is not the same behavior as the String.replaceAll, which uses regular expressions for doing the matching.- Parameters:
string
- the start string. Must not benull
.target
- the target to search for in the start string. Must not benull
.replace
- the replacement string to substitute when the target is found. Must not benull
.- Returns:
- String result. Will not be
null
. If target is not found in the given string, then the result will be the entire input string. - Since:
- 2.1
- See Also:
but case insensitive
-
replaceFirst
public static String replaceFirst(String string, String target, String replace)
Returns the string resulting from replacing the first occurrences of the target with the replace string. Note that the target matches literally, and this is not the same behavior as the String.replaceAll, which uses regular expressions for doing the matching.- Parameters:
string
- the start string. Must not benull
.target
- the target to search for in the start string. Must not benull
.replace
- the replacement string to substitute when the target is found. Must not benull
.- Returns:
- String result. Will not be
null
. If target is not found in the given string, then the result will be the entire input string. - Since:
- 3.0
