Another error...

[andybeeeeee]

This program is going to be the death of me i swear....

Anyway, i've just written a method that converts a location string that's in the format xxyy.zzzz into xx.yyyyyy using a conversion formula that i've been given. when i compile the code i'm getting cannot resolve symbol errors and i havent a clue why.... can anyone help me?

  public double convert (String data){ //example of data "5115.1234 N"

       splitData = new String[2];
       String xs;
       String ys;
       int i, length, j=7, post=0;
       double x, y, z, result;
       double ten=10, power;
       char direction;

       for(i=0; i<2; i++)
       {
           post = data.indexOf(".", j); //split the data in two at the dot
           splitData[i] = data.substring(j, post);
           j=post+1;
       }
       xs = splitData[0].substring(0, 4);
       ys = splitData[0].substring(4);
       x = Double.parseDouble(xs);
       y = Double.parseDouble(ys);

       length = splitData[1].length();
       direction = splitData[1].charAt(length);
       StringBuffer sb = new StringBuffer(splitData[1]);
       sb.deleteCharAt(length);  //the string needs to be put in a buffer to remove the last element
       splitData[1] = sb.toString();
       z = java.lang.Double.parseDouble(splitData[1]);
       power = length - 1;
       z = z / Math.pow(ten, power); //change z to 0.z
       y = (y+z)/60; // conversion formula
       result = x+y;
       return result;

  }

i get the errors on the lines that i've made bold

aaannndeeeeee!!!

you are importing java.lang.*;
maybe also java.lang.Math.*;

I think all of java.lang is imported by default but maybe not all the math methods, not sure.

But the S60_2nd_FP3_MIDP_SDK

does not have pow as a method of Math

maybe your using a later edition?

plugging in your code, i get an error/warning on
splitData = new String[2];
as it should be "String[] splitData = new String[2];"

are you using cldc 1.0? as double is only in cldc 1.1

I SWITCHED THE IDE, sorry, to cldc 1.1, and resolved the double errors, but i have import java.lang.*; like i said, dont know whether you need it or not

it is still erroring on pow, saying unresloved symbol

you may have to implement it manually, creating your own pow method

good luck

cheers jason, i'll have a look tomorrow to see if this fixes it all. i'll have to check the cldc that my fone is using cos it might give me some problems down the line if it doesnt like doubles... and i've made my own power method aswell now. cheers for the help

[Jason Glass]

thats cool man, lemme know if it works. and as far as cldc support, not sure on the percentage of devices with or without, but I know for Motorola, or most motorola, or, thats what I was told to do, we have to use cldc 1.0, so if your trying to get out on as many devices as psosoible, keep it in mind

Hi,

Just for your information, there is no need to explicitly include java.lang.*;

The entire namespace is imported by default, in Java.

cool, was wondering whether or not, thanks juarez, and congrats on poster of the month award!

[andybeeeeee]

yeah it works, cheers jason. getting yet another runtime error now which will be fun to get rid of.....
