Hi, I'v been trying to write a simple Java EE app, which deals with car renting. The entity beans and session beans are ready, so I've created a JSP for representation.

well you have a few mistakes.. For ex. ageOf Interest is what? I mean is it a variable (and should be ageOfInterest)? Then, you define twice the variable trainingzone. The second one should be trainingzone1 or something like that. And to read double values from standard input you need first …

You could try a double variable, like this: [CODE] for (float c=0.0;c<2.1;c+=0.02) { ... } [/CODE] Inside that for, you compute the values for your function, then you save these either in an array of type double, or (if you want them to be available later) into a text file.

I'm sure Google will help you out. Try searching for 'Power Set Java' Why do you take OOP courses (or whatever) if you don't want to learn?

You should read a value, parse it put in your array and then start over. You cannot have parsedouble[] (actually the correct version is parseDouble(args)). When you read a value, you cannot convert it to an array. Just put it to the next location in your array.

Dude, what is this piece of code supposed to do? By the way, first you should take a look on Java syntax. And also, start with 'Hello World' type applications to learn how to write correct, readable Java code.

So, assuming you aren't using arrays with thousands of elements, you can use this [code] do swap = 0; for (int i=0;i<n-1;i++) // n- nr of elements if (anArray[i]>anArray[i+1]) { temp = anArray[i]; anArray[i] = anArray[i+1]; anArray[i+1] = temp; swap = 1; } while (swap) [/code] This is the code …
