Java has the ''trim'' and ''strip'' operations. Both will achieve a similar result.<br />
The <code>trim</code> method works on Unicode values under <kbd>0x20</kbd>. Whereas, ''strip'' will remove all Unicode white-space characters.
<syntaxhighlight lang="java">
" abc".stripLeading()
</syntaxhighlight>
<syntaxhighlight lang="java">
"abc ".stripTrailing()
</syntaxhighlight>
<syntaxhighlight lang="java">
" abc ".strip()
</syntaxhighlight>
<syntaxhighlight lang="java">
" abc ".trim()
</syntaxhighlight>
For more control over what characters should be removed, you could implement your own methods.
<syntaxhighlight lang="java">
String removeLeading(String string, char[] characters) {
int index = 0;
for (char characterA : string.toCharArray()) {
for (char characterB : characters) {
if (characterA != characterB)
return string.substring(index);
}
index++;
}
return string;
}
</syntaxhighlight>
<syntaxhighlight lang="java">
String removeTrailing(String string, char[] characters) {
for (int index = string.length() - 1; index >= 0; index--) {
for (char character : characters) {
if (string.charAt(index) != character)
return string.substring(0, index + 1);
}
}
return string;
}
</syntaxhighlight>
<br />
An alternate demonstration<br />
Java offers <code>String.trim</code>. However, this function only strips out ASCII control characters. As such it should generally be avoided for processing text.

In Wren 'whitespace' is defined as: space, tab, carriage return, and line feed characters. To trim off other non-printing characters such as form feed and vertical tab, you need to do a little more work.
<syntaxhighlight lang="
var b = "String with trailing whitespace removed \t\r\n"
var c = " \t\r\nString with both leading and trailing whitespace removed \t\r\n"
