![]() ![]() ![]() cd C:\Users\comp\Java Practiced program Press enter Step 6: Set the path of Compiler. ![]() Step 5: Use the following command to go to the folder where the previous Java program is stored. The main methods get an array of strings as an argument, these are the command line arguments you may pass to your program.Įvery array in java holds a variable called length that says how many elements are within that array. Note: If you are using multiple classes in your program you will need to compile all of the files. Step 4: Go to the command prompt by using start->Run->cmd OR start-> type cmd in the search program and file. To run it, we need to run java with the name of the class as the argument (Not the file!) Wrong java MyFirstClass.class all java programs are run through command prompt. This will create a file called MyFirstClass.class that holds the compiled java code. Next you can type start command in Command Prompt window.If we take the code from the previous lesson and put it in a file called MyFirstClass.java, in order to compile it we need to run: javac MyFirstClass.java In order for those to be available you must download and install JDK (Java Development Kit). You need to have a console and you need to have the following commands available in order to compile and run Java. It shouldn't really matter if you use Linux, Mac or Windows.
