Trim Last Character from a 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 can I remove the last character of a sentence in JavaScript?

Since the str.slice function returns the sliced part between two index as a substring, in your case, you should use str.slice(0,-1), that is equals to str.slice(0, str.length - 1). And it means that is going to return every character from zero index without the last character of the string passed.

function morseCode(str) {
    morseCode = {
    "A": ".- ",
    "B": "-... ",
    "C": "-.-. ",
    "D": "-.. ",
    "E": ". ",
    "F": "..-. ",
    "G": "--. ",
    "H": ".... ",
    "I": ".. ",
    "J": ".--- ",
    "K": "-.- ",
    "L": ".-.. ",
    "M": "-- ",
    "N": "-. ",
    "O": "--- ",
    "P": ".--. ",
    "Q": "--.- ",
    "R": ".-. ",
    "S": "... ",
    "T": "- ",
    "U": "..- ",
    "W": ".-- ",
    "X": "-..- ",
    "Y": "-.-- ",
    "Z": "--.. ",
    '1':'.---- ',
    '2':'..--- ',
    '3':'...-- ',
    '4':'....- ',
    '5':'..... ',
    '6':'-.... ',
    '7':'--... ',
    '8':'---.. ',
    '9':'----. ',}
    
    str = str.replace(/[!,?]/g , '');
    
    str = str.replace(/\s/g, '');
    
    return str.toUpperCase().split("").map(el => {
       return morseCode[el] ? morseCode[el] : el;
    }).join("").slice(0,-1);  // this returns the string without the last character.
    
};

EDIT:

What I've noticed in this type of questions that quite everyone suggest to remove the last char of given string. But this does not fulfill the definition of Trim method.

Trim - Removes all occurrences of
white space characters from the
beginning and end of this instance.

MSDN-Trim

Under this definition removing only last character from string is bad solution.

So if we want to "Trim last character from string" we should do something like this

Example as extension method:

public static class MyExtensions
{
  public static string TrimLastCharacter(this String str)
  {
     if(String.IsNullOrEmpty(str)){
        return str;
     } else {
        return str.TrimEnd(str[str.Length - 1]);
     }
  }
}

Note if you want to remove all characters of the same value i.e(!!!!)the method above removes all existences of '!' from the end of the string,
but if you want to remove only the last character you should use this :

else { return str.Remove(str.Length - 1); }
