hey,
im very new to programming, and though im not an idiot, feel free to treat me like one.
so i have an assignment in which i have to read a series of doubles, print them, sort them and print the sorted array, all in different methods.
so im pretty sure i could do it in the main, but when i try to return an array from the service method to the main. im getting an error that says .class expected. well i guess i should post the bit.

(Toggle Plain Text)

double[] series = new double[100];
int index=0;
System.out.println("Please input a series of numbers. "+"Input -888 when you are done.");
double y = SavitchIn.readDouble();
while (y != -888)
{
series[index]=y;
index++;
y=SavitchIn.readDouble();
}
return series[];

so if i try to compile that, i get...

(Toggle Plain Text)

Service.java:23: '.class' expected
        return series[];
                  ^
1 error

anyone have any clue what im doing wrong?
i know it seems like nothing but it would be a big help to me. thanks.

(EDITED (SykkN): fixed your [ CODE ] tags ...)

Could you post the whole thing?

Here is the whole service method.
this is what is giving me the error.

(Toggle Plain Text)

public class Service
{
public static char convert(char letter)
{
int x;
x =(int)letter +32;
letter=(char)x;
return letter;
}

public double[] read()
{
double[] series = new double[100];
int index=0;
System.out.println("Please input a series of numbers. "+"Input -888 when you are done.");
double y = SavitchIn.readDouble();
while (y != -888)
{
series[index]=y;
index++;
y=SavitchIn.readDouble();
}
return series[];
}
}

thanks

(EDITED (SykkN): same thing here ...)

I'm no Java coder, but one piece of advice: don't but spaces within the [code] tags.
