Writing to STDOUT, then reading from STDIN?

Question

I have been researching this lately, as i've been programming 5 years and never had the opportunity to use it.
The documentation on the official Java tutorial is pretty scarce, but it SEEMS like i should be able to write to STDOUT, then have it wait for me until i read from STDIN.
I tried the following code:
PrintStream os = System.out;
System.setOut(os);
InputStream is = System.in;
System.setIn(is);
os.write("I HOPE THIS WORKS!!!!!!!!!".getBytes());
int available = is.available();
byte BYTE[] = new byte[6]; //just trying to read the first 6 bytes, for the heck of it!
is.read(BYTE);However, when i run the os.write method, the String just prints to the console. i thought my code was sufficient to reassign it and prevent it from being output there. what am i missing here?
thanks!

I tried the following code:You however are missing the point that a stream has two ends. The streams you are grabbing do not let you control both ends (within java.)
So you need to create a stream, rather than using an existing one.
