How to Remove the Last Character from a String in Java
Being able to manipulate strings is a common task in programming.
One of those tasks include removing the last character of a string.
In this post, we'll look at how to remove the last character of a string in Java.
Removing the last character
To remove the last character of a string, let's first start with our example string:
String string = "Hello World";
Now, we can use the
substring method which takes a start index and an end index and returns a substring of the original string.
We can pass it a start index of 0 and an end index of the length of the string minus 1, which is the index of the last character.
Combined, this has the effect of excluding the last character of the string:
String string = "Hello World"; String substring = string.substring(0, string.length() - 1); System.out.println(substring);
Keep in mind that
substring is a method that returns a new string, so we can't just use it to modify the original string.
That is why we created a new variable to store the new string.
In this post, we looked at how to use the
substring method to exclude the last character of a string.
Just pass in
string.length() - 1 to the
substring method and you'll get the substring without the last character.
