I am trying to take the input and if there is an @ symbol in the input then it finds the maximum of the integers before and after the @ symbol. The maximum part I have no problem with but I do not know how to access and find the values before and after the @ symbol.

import java.util.Scanner;

public class Max_Min {

    public static void main(String[] args) {
        //gets keyboard
        Scanner keyboard = new Scanner(;
        //puts input into string
        String inputString = keyboard.nextLine();
        //splits string between characters
        String[] splitInput = inputString.split("");

        for (String s : splitInput) {
                //computes the maximum of the two integers before and after the @ 


        //close keyboard

I did do a search to find something simliar (and im sure there is something) but could not find anything. If someone could help that would be great!

Try with this:

for (int i = 0; i < splitInput.length; i++){
    if (splitInput[i].equals("@") && i != 0 && i != splitInput.length -1){
        int max = Math.max(Integer.parseInt(splitInput[i - 1]), Integer.parseInt(splitInput[i + 1]));

Index, Slice, Split, and Manipulate JavaScript Strings, Each character in a JavaScript string can be accessed by an index number, We can use the typeof operator to determine the type of a value. Using traversal in the list, append all the index values except the given index to a new list and then print the new list. For this we will require a new list where we can append all the values except the given index value.

You could try:

String[] splitInput = inputString.split("@");

which would split your string at the @s. Then you can do a iteration over your splitInput array and do a .length on each index.

Get value from a string before and after a special character, var pieces = 'Username|Jackie'.split("|") var before = pieces[0] var You can access these values using index based array manipulation or the  However, a document key (both before and after conversion) can't be longer than 1,024 characters. When you retrieve the encoded key at search time, you can then use the base64Decode function to get the original key value, and use that to retrieve the source document.

You have written the simple for loop, with which you can only access the string, but not its index in the array. If you had the index, you could write:

int possibleMax = Integer.parseInt(splitInput[i - 1]) + Integer.parseInt(splitInput[i + 1]);

To get the index, there are two ways:

for (int i = 0; i < splitInput.length; i++) {
    String s = splitInput[i];


int i = 0;
for (String s : splitInput) {

I don't like either version because both are more complicated than absolutely necessary, in terms of written code. If you would use Kotlin instead of Java, it would be:

splitInput.forEachIndexed { i, s ->

In Java this could be written:

    (i, s) -> …

The problem in Java is that the code inside the … cannot update the variables of the enclosing method. I'm not sure whether this will ever change. It would be possible but needs a lot of work by the language committee.

STACS 94: 11th Annual Symposium on Theoretical Aspects of Computer , An indirect- access machine is an usual Turing machine that additionally has a special If an input position greater than the input length is queried, then the machine that the content of the input index tape is not erased after querying the input. will receive the answer (the value of the function) on the oracle answer tape. On the whole, Substring will start at the index position after the @ symbol and Ends when the string ends. SQL Substring Charindex. In this example, We are going to find the string before the @ symbol in the Email Address column. For this, we are using the substring along with CHARINDEX

A simple way to do this would be

String input = "12@23";
String [] arr = input.split("@");
if (arr.length == 2) {
    System.out.println("Max is "+Math.max(Integer.valueOf(arr[0]),Integer.valueOf(arr[1])));

The Internet Encyclopedia, Volume 3 (P, It then finds the longest string of “a” followed by any single character in the rest, and that the string parts that matched the pattern parts are still available after the match for as Files are accessed within a Perl program through filehandles, which are bound associates the file named “index.html” with the filehandle INPUT. When we refer to a particular index number of a string, Python returns the character that is in that position. Since the letter y is at index number 4 of the string ss = "Sammy Shark!", when we print ss[4] we receive y as the output. Index numbers allow us to access specific characters within a string.

Get value from a string after a special character, Assuming you have your hidden input in a jQuery object $myHidden , you then use JavaScript (not jQuery) to get the part after ? need to find DEMO string after - by above code you can able to access DEMO string substr will  Below are the ways to get the value from all types of form elements. In all cases, the form is called feedback and the element is called field. Text Boxes, <textarea>s and hiddens. These are the easiest elements to access. The code is simply. You'll usually be checking if this value is empty, i.e.

Systems Approach to Social Engineering., The EDPS codes can be accessed as files in the program. The results are then compared with designed values to ensure the As symbols (or labels) can appear before they are defined, it is convenient to make It is equal to read label then the index value is placed in location counter, so that, it again scans the input file  Accessing values through slicing - square brackets are used for slicing along with the index or indices to obtain a substring. In slicing, if range is declared [1:5], it can actually fetch the value from range [1:4]
