System.out.println not printing, weird output

Hello everyone I am VERY new to java and have written a simple class to hold the x-coord, y-coord and radius of a circle. So far I have written class, constructor, etc. up until a print of the current x coordinate of the circle.

here is the code:
[Java] mejava2 - Pastebin.com

this is the output, that i am receiving after building and running. PS I am using Netbeans.
javaoutputme - Pastebin.com

Can anyone explain why it is not just printing the x integer, and what all of the stuff in the output means.

Thanks.

after creating your object MyCircle, when are you calling method printx?

I'm not following the external link but if you're having trouble printing your circle's current co-ordinates, i'm just thinking a common mistake for new java programmers would be a type mismatch. The output has to be a String, not a number (Int, Double, etc)

So if your co-ordinates are a number, convert it to a String before you print it, or use the java Formatter e.g.

Code:

---

int circleX = myCircle.getX();
System.out.printf("The current X coordinate is: %d",circleX);

Thank you for your reply, I have been following the oracle tutorials, that is how I am learning. I have reached the point of declaring classes and whatnot, so I was hoping someone could assist me with the printing issue.

Ozzyman, thank you for your help, are you suggesting I create a variable integer, circleX; or that I place "%d" in my output code? I am confused because you told me to create a string, while circleX would be an integer, but I am also unsure because I don't know what %d does.

I don't see anywhere the output of running the code. All you have done is to build the project.

Junky, the output im getting in the Netbeans output window after running is on the page the link leads to, below the text you quoted.

Yes I followed the link and the last line is "BUILD SUCCESSFUL (total time: 0 seconds)". That is building the project not running it.

Yes it says build successful: that happens when I click run. I am not sure what else to click, I figured "run main project" would run my project. I posted this topic because there is no output of the integer of the x coordinate of the circle, which should output "3".

notice System.out.printf is not the same as System.out.print, the 'f' stands for formatter.
there is another way to write this:

Code:

---

String myString = String.format("The number is %d and it is output with a formatter",myNumber);
System.out.println(myString);

---

The java formatter replaces the %d with an integer. 'd' stands for decimal number. So if myCircle.getX() = 3, the output for this code:

Code:

---

int circleX = myCircle.getX();
System.out.printf("The current X coordinate is: %d",circleX);

---

Would be this:
The current X coordinate is: 3
