In this article, we would like to show you how to trim whitespace from string in Java.

Quick solution:

String text = "   abc    ";

String result = text.trim();

System.out.println(result);

 

Practical example

In this example, we use String trim() method to remove whitespaces from the beginning and from the end of the strings.

public class Example {

    public static void main(String[] args) throws Exception {
        String text1 = "   abc";
        String text2 = "abc   ";
        String text3 = "   abc   ";

        String result1 = text1.trim();
        String result2 = text2.trim();
        String result3 = text3.trim();

        System.out.println(result1);  // abc
        System.out.println(result2);  // abc
        System.out.println(result3);  // abc
    }
}

Output:

abc
abc
abc
