Using Java’s Float class.
float f = Float.parseFloat("25");
String s = Float.toString(25.0f);
To compare it's always better to convert the string to float and compare as two floats. This is because for one float number there are multiple string representations, which are different when compared as strings (e.g. "25" != "25.0" != "25.00" etc.)

Float to string - String.valueOf()
float amount=100.00f;
String strAmount=String.valueOf(amount);
// or Float.toString(float)
String to Float - Float.parseFloat()
String strAmount="100.20";
float amount=Float.parseFloat(strAmount)
// or Float.valueOf(string)

Float.parseFloat() or Float.valueOf() should work. You'll get a NumberFormatException if the string can't be parsed. From the exception you've posted it looks like you're trying to cast a Float to a String instead of using one of those methods.

Use Float.valueOf(String) to do the conversion.
The difference between valueOf() and parseFloat() is only the return. Use the former if you want a Float (object) and the latter if you want the float number.
