如何在Netbeans中编译单个Java文件？

Question

I have following code in project called Fork.

package fork;

public class Fork {

    public static void main(String[] args) {

       if (args.length == 1 | args[1].equals("test")) {
           System.out.println("test case");
       } else {
           System.out.println("production " + args[0]);
       }      

    }

} 

Project Structure in Netbeans is as follows:

I am trying to make changes in the Fork.java. It would not build successfully because args[ 1 ] gives an error on runtime, which is alright. So, What I do is compile the Fork.java using "javac Fork.java" command in Terminal outside Netbeans. Then the changes reflect in the output.

For instance, I would run the following command from Terminal in my Mac or from the Terminal within Netbeans (both respond same way): "java Fork live test"

Then I would make some changes in Fork.java and Save it. I have "Compile on save" enabled in my project properties.

I would run again the above command, but the changes would not reflect in the output. To see the changes, I would have to go to the Folder where Fork.java is saved, and then compile it using "javac Fork.java" in Terminal. Then I would run the "java Fork live test" from Terminal and see the changes.

I am interested to see whether Netbeans has any equivalent way to compile a single file.

Answer 1

I'm guessing you want to run Fork with arguments (live test) using the NetBeans IDE. You don't want to go through the command line.

1. Right Click on Cup and Saucer icon -> Properties
2. Go to Run, add live test in the Arguments box
3. Run Project F6.

You code builds successfully using Clean and Build Project Shift+F11
