How can i do a cast from a java.lang.Object to float?

Question

My friend is using Eclipse and doesn't have any problem with this lines:

float secOp = (float) computingStack.pop();
float firstOp = (float) computingStack.pop();

I'm using Netbeans and gives an error in both lines, says that the types are not convertible. I tried to use valueOf() and parseFloat, but any was useful. I'm using generic data for my stack.

Do you have different java development versions?

I think you can't cast from object to primitive type. Did you try floatValue()?

float secOp  =  ((Float)computingStack.pop()).floatValue();
