How to remove last comma (,) of a string in Java

In this tutorial, we are going to learn about how to remove the last comma (,) of a given string in Java.

Using the substring() method

We remove the last comma of a string by using the built-in substring() method with first argument 0 and second argument string.length()-1 in Java.

Slicing starts from index 0 and ends before last index that is string.length()-1.

Here is an example:

String str = "Hello,";

// remove last character (,)
str = str.substring(0, str.length() -1);

System.out.println(str);

Output:

"Hello"
