JAVA: Getting the press any key to continue thing

[Winston]

Hey guys as the thread name implies, how do u do it, im doing console programming in java, and i wann know how to do the press any key to continue thing, so watever key is pressed then it does something, i know how to read user input but i dont think thats how to do it. Thanks

Not 100% sure, but I took a quick look in the API, and I'm guessing you should use KeyListener keyPressed(KeyEvent.KEY_PRESSED).

[Winston]

hmmm i have no idea how to implement it, its so confusing

[kjordan2001]

Don't think you could have a single key press do it since Java reads a line at a time. You could have them press enter, but that's about it.

[Winston]

ok well how do i retrive if enter is pressed?

[kjordan2001]

System.in.read()

[Winston]

wait wait... i need to put this in a if statement

so would it be

if (System.in.read(WHAT GOES HERE?))

{

}

[kjordan2001]

Nothing goes there (unless you want it in a byte[]), no need for an if statement, it just waits for a key press.

[Winston]

ummm so wait

public void Test()

{

[this is a block of code that's executed]

System.out.println("Press enter to return to menu");

System.in.read();

}

ummm but cant i put it in a if statement becoz i need to know when enter has been pressed so that i can call another method

[kjordan2001]

Nothing continues until enter is pressed so put the call after.

[Winston]

Thanks for your help.

hmm...I would still use a keyListener, but I guess it's easier to just use the standard system input.

[kjordan2001]

keyListener is really more for GUI. I'm not sure there's a prewritten class in the Java API for a command line keyListener but they're very easy to use in AWT/Swing.
