Strip Leading and Trailing Spaces From Java String

Is there a convenience method to strip any leading or trailing spaces from a Java String?

Something like:

String myString = "  keep this  ";
String stripppedString = myString.strip();
System.out.println("no spaces:" + strippedString);

Result:

no spaces:keep this

myString.replace(" ","") would replace the space between keep and this.


Solution 1:

You can try the trim() method.

String newString = oldString.trim();

Take a look at javadocs

Solution 2:

Use String#trim() method or String allRemoved = myString.replaceAll("^\\s+|\\s+$", "") for trim both the end.

For left trim:

String leftRemoved = myString.replaceAll("^\\s+", "");

For right trim:

String rightRemoved = myString.replaceAll("\\s+$", "");

Solution 3:

From the docs:

String.trim();
