Java string trim

Java trim() method of String class removes any trailing and leading spaces from a string.

Here trim method does not accept parameters.

Trim method returns the string with deleted spaces.

Example : java string trim

public class TrimJava
   public static void main(String[] args)
      String strOriginal = " Great Barrier Reef";

      String strTrimmed = strOriginal.trim();
      System.out.println("Before using trim() method: " + strOriginal);
      System.out.println("Using trim() method: " + strTrimmed);

Output :

String trim java
Before : Great Barrier Reef
After : Great Barrier Reef


  • trim() method in java uses unicode value, that is, \u0020.
  • unicode value is checked before and after a string.
  • trim() method in java does not remove middle spaces, that is, for example there is a string “Core Java” so the space between “Core” and “Java” will not be eliminated.
