lv_count_last = lv-count - 1.
replace string+lv_count_last(lv_count) in string by ' '.
This should work.

I got a new wireless connection for my mac and cannot figure out how to delete the last connection service I had. Everytime I shut the computer, the network goes back to the other one. I cannot find the file ANYWHERE

Under Network Preferences, select the WiFi
click on "Advanced..." button
Select the network you want to delete from the list and click on "-"
Click "Ok"
Click "Apply"
Well done ;-)
You may also want to delete the wireless key from Keychain.
Open Keychain, seach for the old wifi network name, slect it and click delete

How to delete the last element of a collection without iterating it?

how to delete the last element of a collection without iterating it?

To add to jverd's reply, even if you could determine the last element, in some collections it is not guaranteed to always be the same.
From HashSet:
It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time.

How to delete the last "\n" ??

Hey!
I have a string with alot of "\n" within it, how can i only delete or substring or something to get rid of the last appreared "\n" ?
I generates a text dokument like:
hi "\n"
hi "\n"
hi "\n" Dont want the last one "\n" here!!
Can i do that with substring ?
/Thanks
Mike

There is a substring method like this:
substring(int beginIndex, int endIndex)So you could use the lastIndexOf() mehod to find the last index of "\n", then use the substring method.

How to select the last elements in a string

Hi Guys
I am using UART RS232 protocol and i need to calculate the check sum. My data came in decimal and in the end it must be doubles to manipulate it. So my problem is, for example, the sum of all elemants is in decimal 1742 and in hex is 6CE and i wont only the last two elemants, CE that corresponds to 206 that is the result of my checksum. Can anyone help me?
Thanks

Thanks Syrpimp
My data came from HMI in decimal like the example that i show above. Each cell is a value. You used an array, but i think that i can't use it because it must be done automatically and the data field have variable length.
The UART protocol frame has a start frame field that corresponds to two ‘{‘ characters and an end frame field that corresponds to two ‘}’. Additionally, besides the data field, that has variable length, it has a byte that corresponds to the command type and another that is the checksum. The following table illustrates the protocol.
Bytes considered in checksum
Command Data
Start Frame
Cmd
(hex)
Data0
Data1
Data2
Data3
Data4
Data5
Data6
Data…
CHK SUM
End Frame
1 Byte CHK SUM (sum of all data bytes truncated to 1 byte)

I receive data like this:

you just copied and pasted what the OP had written

to make me look like

kind regards,
JosNope, I used the Alt-[numeric code] combinations to manually type each character. Cut-n-paste is for wimps, and actually typing single-stroke keys is for milquetoasts.

Read last char of a String

I have the following code that functions like a basic RPN calculator:
public class Main {
     * @param args the command line arguments
     static public ArrayList<Double> stack = new ArrayList<Double>();
     static double numberInput;
     static double answer;
     static String operation;
//Prints Welcome screen, initialized checkforInput
     public static void main(String[] args) {
         System.out.println();
         System.out.println("Welcome to RPNCalc by theCoffeeShop()");
         checkForInput();
//Checks for input, redirects to appropriate method
     public static void checkForInput() {
         Scanner reader = new Scanner(System.in);
      String input = reader.nextLine();
         if(isDouble(input) == true) {
            double number = Double.parseDouble( input );
            stack.add(0, number);
            repeat();
         } else {
            operation = input;
            operation();
//Processes numeric operations
     public static void operation () {
         if(operation.equals("+")) {
             answer = stack.get(1)+stack.get(0);
             stack.add(0, answer);
             System.out.println(answer);
             repeat();
         } else if (operation.equals("-")) {
             answer = stack.get(1)-stack.get(0);
             stack.add(0, answer);
             System.out.println(answer);
             repeat();
         } else if (operation.equals("*")) {
             answer = stack.get(1)*stack.get(0);
             stack.add(0, answer);
             System.out.println(answer);
             repeat();
         } else if (operation.equals("/")) {
             answer = stack.get(1)/stack.get(0);
             stack.add(0, answer);
             System.out.println(answer);
             repeat();
         } else {
             System.out.println("Incompatible operation");
             repeat();
//Called when ready to recheck for input
     public static void repeat() {
         checkForInput();
//Checks if string is double
     public static boolean isDouble( String input )
        try
            Double.parseDouble( input );
            return true;
        catch(Exception e)
           return false;
}To perform a basic operation (5+2), you would do the following
5
enter
2
enter
(plus)
enter
Computer prints 7.
I would like it to function like this:
5
enter
2(plus)
enter
Computer prints 7.
To do this, I have to be a be to split a string into 2 parts, the operation and the number. I think I could do this with a StringBuffer, but How to read the LAST char of a StringBuffer, instead of just a specific char? If there is a way to do it w/out a StringBuffer, I'm open to suggestions.

Hint:
The last character of a String (or StringBuilder or StringBuffer, etc.) is at the index (length_of_string - 1).
Are you sure you're supposed to solve the problem this way? Usually homework assignments of this sort involve writing a whole parser.

Hi Kumar,
I think you can just delete it in the sales order directly, if you are using make-to-order scenario, then there will be special stock left for the sales order as the production has been goods receipt, you need to use MM transaction move the stock to unrestricted use stock. If you are using make-to-stock scenario, there should be no further problem. If you are using assembly order, please try to reject the sales order item to see if it could fullfill your requirement.

Rachel
