Hiho,


just got some Problem when using program-snippets that are using Exeptions.
For Example:

Code: Select all

import lejos.nxt.*;

public class BatteryTester {
    public static void main(String[] args) throws Exception {
   


        LCD.drawString("Battery: " + Battery.getVoltage() + " Volt", 0, 0);
        LCD.drawString("Battery: " + Battery.getVoltageMilliVolt() + " mVolt", 0, 1);
        Thread.sleep(5000);

    }
    }


When trying to compile i always get:

Code: Select all

Compiliere C:\java-src\BatteryTester.java mit Java-Compiler (Mindstorms-Modus)
.\Exception.java:1:1: class or interface expected
try {
^
.\Exception.java:6:5: class or interface expected
    throw e; //Leite nach oben weiter
    ^
.\Exception.java:7:1: class or interface expected
} catch (Exception e) {
^
.\Exception.java:10:1: class or interface expected
} catch (OutOfMemoryError e) {
^
.\Exception.java:13:1: class or interface expected
} catch (Throwable t) {
^
.\Exception.java:16:1: class or interface expected
} finally {
^
.\Exception.java:19:1: class or interface expected
}
^
BatteryTester.java:4:51: cannot access Exception
bad class file: .\Exception.java
file does not contain class Exception
Please remove or make sure it appears in the correct subdirectory of the classpath.
    public static void main(String[] args) throws Exception {
                                                  ^


Thanks in advance for your help.

The code seams fine for me. Can you give a description of the command you're using? (I assume your using the command line), what version of lejos are you running?, have you got classes.jar on the classpath?.

Thanks,

Chris

It looks like you have a file called Exception.java in the same folder as BatteryTester.java. You should remove Exception.java. Do you have such a file? If so, what are you trying to do with it?

Thanks a lot. Indeed there was a Exception. java in the wrong place^^
