As it could simply be: String result = otherClass.getComplicatedCalculatedText(par1, par2). Removing a character using replaceFirst() method Removing a character using replaceAll() method Removing a character using substring() method Removing a. Obviously I'd need to use a local variable, which is so unnecessary at this point. OtherClass.getComplicatedCalculatedText(par1, par2).length() - 2) Also, think of that: If you determine the string, it becomes even unhandier: String result = otherClass.getComplicatedCalculatedText(par1, par2).substring(0, Q: why is text.substring(0, text.length() - 2) not good enough?Ī: It's very bulky if you compare it with my desired function. I just don't build something like that on my own, although it's trivial. Plus: I work in many different projects and just want to rely on a simple library call like "Strings.nullToEmpty(str)" etc. I go with the opinion that there MUST BE something available already as I would say that tons of people need this kind of function pretty often in their lifetime. I don't write a util method for "null or empty" or other trivial things. Q: Why don't you just build your own util method / class?Ī: I don't want to use an own util method. I know there are many String libraries out there, but don't know many of them and I never saw something like that so I hoped someone of you might know better :) I rather want to do something like: String result = text.cutOffEnd(2) I now would do the following: String result = text.substring(0, text.length() - 2) Let's say I got "Helly there bla bla" and - why ever - I need to cut off the last 2 characters, resulting in "Helly there bla b". Sb.delete(str.length() - 1, str.Everytime I encounter this I ask myself the same question: Isn't there a simpler and less annoying way of cutting a string from the end by X characters. Sb.delete(str.length() - 1, str.length()) This deletes the characters from the specified first index till the specified second index in the given string. We can delete the last character from the string using the delete() method provided in the StringBuffer class. The new string after replacing with a space: string.replace(char oldChar, char newChar) The first parameter is the substring to be replaced, and the second parameter is the new substring to replace the first parameter. ("The new string after replacing with a space: ") The first and most commonly used method to remove/replace any substring is the replace () method of Java String class. It parses two parameters one in which we have to check to which character does it match and the other one is the character to be replaced with the matched character. This is just a regular way to remove or delete a character from the string. Using this function we can remove the last character of the string by providing the index number in the parameter of the method. In StringBuffer, we have leteCharAt() function. This creates a reasonable space in the memory called Buffer. We can declare an object of StringBuffer type. StringBuffer is another type of class with some added functionality to handle strings. (excluding the character present at the last index). It will return a set of characters simultaneously from the starting index up to the last index of the string. We can remove the last character from the string using the substring() method. You can also check: How to remove a particular character from a string in Java? Ways to remove the last Character from String in Java 1) String substring(): There are different ways in which we can remove the last character. Here, we will see how to remove the last character from String in java. Like Math and character classes, String classes also possess some useful functions to operate or manipulate string data. It allows the user to create an object or declare a variable to store a set of characters. Java Class Library(JCL) contains a class called String which is available under java.lang package. In this tutorial, we will learn to remove the last character from String in Java in different ways.
