you cant do var.length - 1?

Got an incompatible type error...

public static double mean (int x[ ]){
        int total = 0;
        for (int i=1; x.length - 1; i++)
            total = total + x[i];
        return (total/x.length-1);
    } //end method mean

x.length-1 is an int expression; you need a boolean expression for the 'for-condition' part; you probable meant:

for (int i= 1; i < x.length-1; i++)
   // ...

kind regards,

You have done mistake in for loop,
at the place of condional statement(i.e. x.lingth - 1).
To overcome this error,
either,you have to give any boolean type value or any conditional statement there,
then only the error can be removed.
as like...

for (int i=1; i< x.length ; i++)
total = total + x[i];
