Java reference

String.strip()

Removes any Unicode whitespace from both ends of a string.

Available since: Java 11

Syntax

public String strip()

Return value

StringA new string without leading and trailing whitespace.

Examples

Stripping both ends and only one end:

void main() {
    String s = "  hi  ";
    IO.println("[" + s.strip() + "]");
    IO.println("[" + s.stripLeading() + "]");
    IO.println("[" + s.stripTrailing() + "]");
}

Output:

[hi]
[hi  ]
[  hi]

strip() also removes Unicode spaces that trim() keeps:

void main() {
    String s = " text ";
    IO.println(s.trim().length());
    IO.println(s.strip().length());
}

Output:

6
4

Notes

Whitespace is whatever Character.isWhitespace() returns true for. The non-breaking space is not included and is removed by neither strip() nor trim().
