As this is pretty much the first program I've ever written, I decided to write a program to ask for two integers and add them both together and then present them to the user (the goal eventually being a basic fully working command line calculator with +,-,* and /. Java files contained within a folder and after trying to figure out how to compile all three files (as they use one another) all at once, I came across this -> javac *.java I'm expecting many compile errors but not the following errors below.

Void accept(String str, float no, float bal) View Replies View Related Compile Error In Line Bufferedreader InputOutput.java:10: error: cannot find symb So I typed this in the command line whilst in the directory containing the three files assuming *.java is the best approach and then I receive the following errors: Jgrasp cannot find symbol how to# I'm writing basically my first program for school. I've written small ones, following instructions, but this is the most vague. I'm not done with the code, but I think the ArrayList is throwing me off. View Replies View Related Compile Error In Hello Java Program I'm trying to gather user input and sum the total. When I am compiling(with javac hellojava.java) it shows following error:Ĭannot find symbol public static void main(string args), and also says package system doesnot exists ("hello java") View Replies View Related Compile Error - Cannot Cast From Integer To Byte Then i saved this file with name hellojava.java(notepad) in C drive in separate folder c:myjavaapp(not in c:java folder). I have a msg object that contains an ArrayList collection. However, in order to send the elements in the array over the udp socket, it needs to be sent as a byte array. ![]() ![]() ![]() So why am I using ArrayList over byte array in first place? Well when I receive data from socket from embedded c program, I need to get an unsigned representation of the data, and thus I need to store it in integers, since bytes in Java are unsigned and unsigned chars in c that are greater than 127 will yield incorrect values in java. I found an error in these code when I compile it How can I resolve this? View Replies View Related Compile Error - Code Uses Or Overrides Deprecated API The problem is I get an "Cannot cast from Integer to byte" when trying to cast the integer to byte: data = (byte)m_data.get(i) Java Code: byte data = msg.toByteArray() ĭatagramPacket response = new DatagramPacket(data, data.length, So I convert the ArrayList to a byte array: But when I send an ack back over the socket, I need to send the data back as bytes.
