floats and Float objects

[joe weakers]

Hi there. Just a quick question on floats and Float objects. I am trying to insert into a Properties object a String and a float. Code is as follows

Properties props = new Properties();
props.put(String value, float value); //this gives the error

Error(61,18): method put(java.lang.String, float) not found in class java.util.Properties

I know there is the idea of the Float object as oppose to the simple float value. Will inserting a Float object overcome my problem and if so how do I convert a float into a Float object. Cheers Joe

Check out the documentation for java.util.Properties. Especially the line that says:

Each key and its corresponding value in the property list is a string.

So you can't set a property to a Float or a float. You can, however, convert a float to a String using String.valueOf(). To do the conversion in the other direction, consult the documentation for java.lang.Float.
