Ask for user input on the same line

[QuantumPhysics]

Okay well, you guys were right, Java is easy is to learn if you are fluent with other languages. Anyways, the year just started and all but I just want to ask one question that's been bothering me quite a bit. I am using the Eclipse Indigo IDE. The question I want to know is after I prompt the user to input a line during run-time it asks for input on the next line as so:

Please enter a number:
5 (user entered number)

How can I change it so that it asks for input next to the end of the line and not below the statement like here:

Please enter a number: 5

I know with C/C++,Python,COBOL and FASM this is default but, well of course java having all its stupid malfunctions this annoys me... How do I ask for input on the same like what would i change

int input;
Scanner user_input = new Scanner(System.in);
System.out.println("what command is used?");
input = user_input.nextInt();

Any help would be great! Thanks.

[Simply replace System.out.println with System.out.print. Print does not add a newline, println does.

Oh lol never even thought of that. My teacher said that the only way to output text is to type system.out.println. Thanks Insectoid, that worked well!

Java:

System.out.println("what command is used?"); input = user_input.nextInt();

I spy a potential error

[QuantumPhysics]

Nope, no error

Indeed. How about an error message?
