Removing the leading and trailing spaces from a string in Java

To remove the leading trailing whitespace from a given string, we can use the built-in String.trim() method in Java.

In this example, we are removing the leading trailing whitespace from a place string.

public class Main
{
    public static void main(String[] args) {
         String place = "  Manhattan ";
         String trimStr = place.trim();
         System.out.println(trimStr);
   }
}

Output:

"Manhattan"

Similarly, you can also use the following regex pattern inside the replaceAll() method to trim it.

public class Main
{
    public static void main(String[] args) {
         String place = "  Manhattan ";
         String trimStr = place.replaceAll("^\\s+|\\s+$", "");         System.out.println(trimStr);
   }
}
