System.out will not flush before input

Question

Hello everyone,
I am using Netbeans 5.5, JDK6, and J2EE. I am new to the environment so I wrote a test application that would prompt a user to enter a string and then echo it. I have:
String str = "";
BufferedReader br = new BufferedReader(new nputStreamReader(System.in));
System.out.print("Enter a string: ");
System.out.flush();
try
str = br.readLine();
catch(IOException ex)
System.out.print(ex.toString());
System.out.print(str);
What is really bizarre is that System.out will NOT flush no matter what. My application will always ask for input before it even prompts the user for the string. This is what the output looks like when running:
init:
deps-jar:
compile:
run:
hello
Enter an string: hello
BUILD SUCCESSFUL (total time: 5 seconds)
Notice how I had to enter the string first? The only way that I have seen that it flushes is if I used println() instead of print. But what if I don't want the prompt to have an end line in it. This just seems like weird behavior. Also, I have tried using a Scanner for input and the results are the same. Not really sure what to do. Any help would be most appreciated. Thanks.

Answer 1

are you running this inside netbeans as well? the "console" view in netbeans (and eclipse, and probably other IDEs) is not a real console, it's a GUI component that the IDE writes to. it's behaviour isn't guaranteed to act like a real console. I've seen this sort of thing on eclipse before, but never used netbeans. but it still stands that an IDE's console view isn't an actual console/terminal window. that may well be the root of the problem
