Delete the last two characters of the String

Question

How can I delete the last two characters 05 of the simple string?

Simple:

"apple car 05"

Code

String[] lineSplitted = line.split(":");
String stopName = lineSplitted[0];
String stop =   stopName.substring(0, stopName.length() - 1);
String stopEnd = stopName.substring(0, stop.length() - 1);

orginal line before splitting ":"

apple car 04:48 05:18 05:46 06:16 06:46 07:16 07:46 16:46 17:16 17:46 18:16 18:46 19:16

Solution 1

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

Solution 2

Use String.substring(beginIndex, endIndex)

str.substring(0, str.length() - 2);

The substring begins at the specified beginIndex and extends to the character at index (endIndex - 1)

Solution 3

You may use the following method to remove last n character -

public String removeLast(String s, int n) {
    if (null != s && !s.isEmpty()) {
        s = s.substring(0, s.length()-n);
    }
    return s;
}

Solution 4

You can use substring function:

s.substring(0,s.length() - 2));

With the first 0, you say to substring that it has to start in the first character of your string and with the s.length() - 2 that it has to finish 2 characters before the String ends.

For more information about substring function you can see here:

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

Solution 5

It was almost correct just change your last line like:

String stopEnd = stop.substring(0, stop.length() - 1); //replace stopName with stop.

OR

you can replace your last two lines;

String stopEnd =   stopName.substring(0, stopName.length() - 2);

It may not work if we increase the string size. So I think it's better to remove from the last what is seen in other answers.

@masud.m updated the answer as you suggested.

Why does Java doesn't want to clean this functionality up? String parsing is extensively used in Orgs of every scale. In Python its as simple as s[:-2]. That's it.

[Harini Sampath]

should be str.length - 3

@Sankalp, Python is easier to learn, but it is slow and sometimes unpredictable. In Java you type more code, but you get fast and reliable result.
