  • How to get Max and Min value entered in a DOS console?

    Hi there? I wanted to get the Maximum and Minimum value that I entered in a console and displays it. This is using the java.lang.Math class and using it's method max and main. please help. thanks - new to java

    Sounds like you need very basic advice: Start with the tutorials: http://java.sun.com/docs/books/tutorial/index.html
    And if the algorithm is the problem:
    - Make two variables that hold the current maximum and minimum value
    - whenever a value is entered, compare it with the minimum, if it is smaller, set the minimum to that value
    - ditto with maximum
    at the end the two variables contain the maximum and minimum values.

    Hi Guys
    I know the program which I did is stupid .. I am getting the result for max and min value?
    But I how can I get the value of km, h, lit in one line
    Equno..max_date,min_date,min_value_km..max_value_km....min_value_h...max_value_h...min_value_l...max_value_l
    with my program i am getting the vlaue of max and min value but not in one line.
    the main parameter is recdu which is KM,L,H
    Can anyone tell me the logic please

  • I am a rookie and need help with max and min values

    Hello all, i am into this intro to java class. my assignment is to write a program that prompts the user for two integers and then prints the sum, difference, average, product , distance (absolute value of the difference) Maximum(largest of the two) and Minimum(smallest fo the two) here is my code so far
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.lang.Math;
    public class Sample4

          try // attempt the following
    {           // create the stream to read from
    InputStreamReader istream = new InputStreamReader(System.in);   // create a buffer to hold the stream
    BufferedReader console = new BufferedReader(istream);           // prompt the user
          System.out.println("Enter a number please");              // get input as a string
          String input = console.readLine();                        // convert to an integer
          int num1 = Integer.parseInt(input);

          int sum = num1 + num2;                                    // get the sum of the two inputs
          int difference = num1 - num2;                             // get the difference of the two inputs
          int product = num1 * num2;                                // get the product of the two inputs
          int average = sum / 2;                                    // get the average of the two inputs
          int abs = Math.abs(difference);                           // get the absolute value of the two inputs
              // new section

    } // if something breaks, catch the exception
    catch (IOException e)
       System.out.println(e); // displays the exception
       System.exit(1);  // quits the program
    }what will be the right syntax or code to find the MAX and MIN values of two numbers a User Inputs, hope someone can help with this. thank you for your help.

    Thanks alot man, sheesh i do not know why my book
    doesnt give me all the static methods. but i do really
    appreciate your help. peaceA complete list of the java.lang.Math methods can be found at http://java.sun.com/j2se/1.4/docs/api/java/lang/Math.html
    btw,
    max(a, b) == (a > b) ? a : b

    Hi there,
    Create 4 column,
    1st will show regular values for the key figure,
    2nd will show Cumulative value, in Query Designer, Just right click on the this 2nd key figure properties, calculation tab there you can check on Cumulated option, and define the calculation direction as Calculate along the Column.
    3rd will show Minimum value , Just right click on the this 2nd key figure properties, calculation tab calculate single valuea as minimum.
    4th will show Minimum value , Just right click on the this 2nd key figure properties, calculation tab calculate single valuea as Maximum.

  • Get old and new values from DBTABLOG table

    Hi,
    I am developing a report to display all changes to some fields of PKHD table over a date range. CDHDR & CDPOS do not capture the changes while DBTABLOG does.

  • Report required max and min value on daily basis

    Hello EXPERTS
    I have requirement to create a report. Requirement is like this. I have a dealer say d1. This dealer has 6 supervisor say sup1, sup2, sup3…..sup6. Daily they open jobcards.
    suppose on 1st march sup1 opened 6 jobcard, sup2 opened 4, sup3 8 and so on. similarly on 2nd march sup1 opened 5 sup2 6 sup4 15 and so on.
    I have all dimension and facts are available.
    The report should display this
    -------------------------------------------------- 1-Mar ---------2-Mar
    Max no of open jobcard per sup------ 8--------------- 15
    Min no of open jobcard per sup------- 4----------------- 5
    Your help will be much apriciated
    Regards

    Hello David,
    Thanks for response. But the below solution is not meeting our requirement. By doing this, it is giving the total no of Jobcard opened on a particular date.
    I have a requirement , suppose on 1st march supervisor 1 opens 20 jobcard, sup 2 opens 25 jobcards and sup 3 opens 15 jobcards. So, if i am selecting max value then my result should be like this
    March 1 --------------------------- 25

  • Get , store and retrieve values from JComboBox, JT.......

    please can you show me how to collect informations from some JComponents like JComboBox, JList , JTextField, JTextArea etc and store them on clicking on a single button and also retreiving them by clicking on another single button

    below are some functions that u can use:
    JComboBox: getSelectedItem()
    JList: getSelectedValue()
    JTextField, JTextArea: getText()
    basically u need to have button, add an action listener for the button, and store the value using the above functions when the button is clicked.

  • Finding difference between Max date and Min date from single date field

    Dear Experts,
    Here I am with a scenario where i didnt find any solution in SDN and in most threads it is unanswered.
    I have 1 KF which is a date field. With reference to Serial no, I want to find out the Max and Min date from the same KF. I created 2 CKF where the same KF is used in both CKF to find the Min and Max dates,
    Ex:
    Serial No | Material | Actual Del date | Max | Min | Difference
    0123 | 300012 | 01.01.2009 | 31.01.2009 | 01.01.2009 | 30
    0123 | 300013 | 07.01.2009 | 31.01.2009 | 01.01.2009 | 30
    0123 | 300018 | 15.01.2009 | 31.01.2009 | 01.01.2009 | 30
    0123 | 300014 | 30.01.2009 | 31.01.2009 | 01.01.2009 | 30
    0124 | 300019 | 02.01.2009 | 10.01.2009 | 02.01.2009 | 8
    0124 | 300012 | 06.01.2009 | 10.01.2009 | 02.01.2009 | 8
    0124 | 300017 | 10.01.2009 | 10.01.2009 | 02.01.2009 | 8
    This is the way how I want the output where now I am able to get the values right till Max and Min and not the difference. I even created the 3rd CKF the find the difference but it is not working.
    How can I find the difference between the Max and Min dates?
    Regards,
    Chan

    Hi
    You have FM --DAYS_BETWEEN_TWO_DATES you can use this while Customer Exit.
    Try to Have 2 RKF for Min Data and Max Date and create a formula/CKF on the same ..
    Hope it helps

  • How can i write max and min data online during acquisition

    Hello,
    I am not keen with programming and your help will be greatly appreciated.
    I make temperature acquisition from an IR camera and I record online 38 different spots at a frequency of 10 samples/min.
    I also record two temperatures from thermocouples at the same sampling rate.
    I would like to make the acquisition during 5 sec every 20 sec and extract the max and min temperature from the thermocouples and write these values in a text file like show below :
    Temp_max 5 sec 22.1
    Temp_min 5 sec 2.1
    Temp_max 10 sec 42.1
    Temp_min 10 sec 4.1
    Temp_max 15 sec 82.1
    Temp_min 15 sec 6.1
    I also would like to make the same with two or three different spots of the IR camera. I think that if I have a good solution for the thermocouple, I can make it for the camera.
    I use LabView 8.2 with NIDaqmx acquisition.
    Thank you in advance

    Hello Evrem,
    Thank you for your advice. In fact, I have already attended to the training course you mentioned. I should think about going to the module Basic II. I do not have problem to connect/pilot various type of instruments but I am not very efficient with loop and arrays !
    I am fine with the data acquisition and the timing and I can sort data during 5 sec with "Array max & min". Then, I can display all data. What I have problem to do is to extract the max & min from the array, keep these 2 values for being writtten in a file at the end of my loop and start again during the next 5-sec cycle. At present, I only have the last max & min results from the last acquisition !
    Any example of how recording max & min online during 5-sec cycle acquisition will be welcome.
    Best regards,
    Labdummy

  • Thread use to find max and min in an array of objects??

    Hello everyone,
    I need to find the min and max int value in a array of Objects.
    This has to be done using threads--like divide the entire array into 10 or so blocks and find the local min and max in each block., Each block is run on a thread and finally comparing them to find the global max and min.How should I do this? I am new to Java programming and in particular to threads.
    Thanks for your time and patience in answering this newbie question.
    JP

    Hi,
    if i understand your problem, you have a big array with a lot of int values and you need to create a few arrays with a part of the big one in each, next each in a thread find the max and the min, next return the max and the min of each thread and compare these max and min to obtain the globals max and min?
    In that case you can create a class in which is your big array. you create a second class implementing Runnable, in its creator you put the instance of the
    first class and 2 int which are the beginning and the ending index. in this class add a method run in this method you create a loop to compare the current value to the max and min values, and you replace if you need to do. In the first class you put the main where you create a few instance of the second class in a thread :
         private Thread threadName = new Thread(new SecondClass(this, start, end));
    Next you start all these thread:
    threadName.start();
    At the end of the run method of the second class you have to write your result in the max and min fields of the first class(int type, you have to create it)
    Write it only if it's necessary (if the current max is > than the already existing max).
    I think it's complete!
    Sorry if it's not really easy to understand, I'm french, but you can answer if you have more questions.
