System.console() issue with Mac OS X

[j***@gmail.com]

Hi,

I am running NetBeans 8.0.1 on a Mac running Mac OS X. I am trying to
set up a program to read user entry from the keyboard. I use the
following code:

----------------------------------------------

Console con;

...

try {
con = System.console();
if (con != null) {
selection = con.readLine();
}
} catch (Exception ex) {

}

----------------------------------------------

The problem is, even after the step con = System.console();, the
debugger says that con is null. Do I need to set up something on the
Mac itself, or are there problems with the code?


Thanks,

Jim

Console is weird. Never seems to work in any IDE

use something like this:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
br.readLine();

That should work reliably for you.
