Question

I am new to java programming, Ubuntu, and Eclipse (usually work on win7 ultraedit/monodevelop/visualstudios with C#, C++, MONO, PHP)

I have installed the java-sdk ( + tons of other java packages ) on my machine + Eclipse and cannot run a simple project through Eclipse.

I can build a .java file, by executing the java file in the terminal using javac to build the class file and java file.class to execute it. I want to use eclipse to build and run my project and it’s not working.

In my eclipse run configurations I have it using the JRE java-6-sun-1.6.0.26 (which is installed) but it’s still not working.

When I try and run a simple project

public class main {

    /**
     * @param args
     */
    public static void main(String[] args)
    {
        // TODO Auto-generated method stub
        while(true){ }
    }

}

the only thing in the console is:

main(1)[Java Application] /usr/lib/jvm/java-6-sun-1.6.0.26/bin/java (Sep 20, 2011 12:22:12 PM)

That path and file does exist. I don’t know what’s going on.

Answer 1

You have an infinite loop in your main method. This will run for ever without doing anything.

Try

public static void main(String[] args)
{
    // TODO Auto-generated method stub
    while(true){
        System.out.println(new java.util.Date());
    }
}

and run again.
