    Unhappy Please Help my teachers suck!!! - keyboard input-

    all i want to do is to simply read in character input from the keyboard

    i have been told to use some thing like

    String MyString = "";

    inputstream isr = new inputstream(system.in);
    Bufferreader br = new bufferreader(isr);

    system.out.print("please enter a number");

    MyString= readline

    Please help i understand this is only half of it and i know this code is very wrong, but i need to use programming lines simular to this else i will fail

    Thank you

    James

    You're almost there...

    .. except for quite a few spelling errors... Note the places where I have
    used uppercases.

    Code:
    String MyString = "";
    
    InputStream isr = new InputStream(System.in);
    BufferedReader br = new BufferedReader(isr);
    
    System.out.print("please enter a number");
    
    myString= br.readLine();
    int myInt;
    // if this is going to be a number then check that this really is a number
    // for this example I'm checking for an integer (no decimals)
    try {
      myInt=Integer.parseInt(myString);
    } catch (NumberFormatException nfe) {
      System.err.println(myString+" is not a valid integer");
    }
