What errors? Compile time? Runtime? Post them in their entirety, and please wrap your code in the code tags.

1) if you want to use addActionListener(this) the class temp must declare and implements the ActionListener. Remember that the ActionListener is in the package java.awt.event.ActionListener and using import java.awt.* the classes in java.awt.event will not be imported!
2) float is a primitive type and has not methods, so you can't use float.parseFloat() but Float.parseFloat() will work.
3) b1 is not initialized, so using add(b1) will throw a NullPointerException. b2 is initialized twice.
4) why is there a call to show()? it seems to be obsolete.
