publicstaticString usingStringUtilsSubstringMethod(String text) {intlastIndex = text != null ? text.length() - 1 : 0;returnStringUtils.substring(text, 0, lastIndex); } Conclusion In summary, we have covered in-depth different ways to remove the last character from a string in Java. We exp...
We can also remove the last character (or any number of characters) from aStringby making good use of regular expressions. For example, we can use thereplaceAll()method of theStringclass itself,which takes two parameters: the regular expression and the replacementString: TEST_STRING.replaceAll("...
Else, we move to the next character.After iterating over the string, we update our string to the new string we created earlier.Code:/*Java program to remove non-alphanumeric characters withMethod 1: Using ASCII values*/public class Main {// Function to remove the non-alphanumeric ...
