How to Efficiently Remove Leading and Trailing Spaces from Strings in Java?

Convenience Method for Removing Leading and Trailing Spaces from Java String

In Java, there's a need for a convenient method to remove any leading or trailing spaces from a string. Consider the following example:

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

The desired result is to print "no spaces:keep this" without the leading and trailing spaces.

The trim() Solution

Instead of using replace() to remove the spaces, we can employ the trim() method, which specifically targets leading and trailing whitespace characters.

String newString = oldString.trim();

Javadocs for Reference

For further details, refer to the official Java documentation: https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#trim()
