Delete Last Char of String

How to remove the last character from a string?

replace will replace all instances of a letter. All you need to do is use substring():

public String method(String str) {
    if (str != null && str.length() > 0 && str.charAt(str.length() - 1) == 'x') {
        str = str.substring(0, str.length() - 1);
    }
    return str;
}

Delete the last two characters of the String

Subtract -2 or -3 basis of removing last space also.

 public static void main(String[] args) {
        String s = "apple car 05";
        System.out.println(s.substring(0, s.length() - 2));
    }

Output

apple car

How to remove first and last character of a string in Rust?

You can use the .chars() iterator and ignore the first and last characters:

fn rem_first_and_last(value: &str) -> &str {
    let mut chars = value.chars();
    chars.next();
    chars.next_back();
    chars.as_str()
}

It returns an empty string for zero- or one-sized strings and it will handle multi-byte unicode characters correctly. See it working on the playground.
