I am new to J2ME and am trying to do a simple app for a blackberry. I am trying to read a user's input using a BasicEditField and then convert this to a float do some math and convert the float answer to a string and write back out again.
java:171: valueOf(java.lang.String) in java.lang.Float cannot be applied to (net.rim.device.api.ui.component.BasicEditField)
float cf = Float.valueOf(capf)
If I try to convert to a string first, I get the following error:
java:169: toString() in java.lang.Object cannot be applied to (net.rim.device.api.ui.component.BasicEditField)
String sx = toString(size);
Any suggestions on how to read input, do the math and write output?

You're going to have to get the VALUE stored in the BasicEditField. BasicEditField isn't a String, it's a UI control class.
