Hallo,

Heb hier een java programma dat een controle doet als er argumenten worden
meegeven via de command prompt. Bv. java MetOfZonderArgumenten in.txt
out.txt

Maar, hij geeft volgende foutmelding

Volumes/Extra/Development/JavaDev/MetOfZonderArgumenten.java:6: cannot
resolve symbol
symbol  : method length  ()
location: class java.lang.String[]
        if (args.length() == 0) {
                        ^
1 error
Process javac exited with code 1


En hier volgt de code

import java.lang.String;

class Controle {
    public boolean hasArguments(String[] args) {
                
        if (args.length() == 0) {
            return true;
        }
        else {
            return false;
        }
    }
}

public class MetOfZonderArgumenten {
    public static void main(String[] args) {
        Controle argumenten = new Controle();
        if(argumenten.hasArguments(args)) {
            System.out.println("GEEN");
        }
        else {
            System.out.println("WEL");
        }
    }
}

Wat loopt hier fout ?

Alvast bedankt voor de tips

Mvg,

Christof
