I know I can open cmd with this code

Runtime.getRuntime().exec(new String[]{"cmd.exe","/c","start"});

but i want to create JButton for open cmd ,run command and show result in cmd screen(not console java) together.

ex. open cmd and run command "java -v" for check java version or "npm install"

my code

btnChkVersion.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            //I DONT KNOW :(
        }
    });

I'm afraid we don't know either, what don't you know? – Mar 01 '17 at 18:08

So what happens when you use the first code snippet inside the second one? – UnholySheep Mar 01 '17 at 18:11
@UnholySheep it show cmd screen only one but i want to run command(ex. java -v) together – salmorn Mar 01 '17 at 18:17
And if you adapt the array to be `{"cmd.exe","/c","start","java","-v"}` you don't get that result? I'm still unsure what exactly the problem is (or what the exact result is supposed to look like) – UnholySheep Mar 01 '17 at 18:36
Why not just query the java version inside the runtime? – Mark Rotteveel Mar 01 '17 at 19:05
@UnholySheep {"cmd.exe","/c","start","java","-v"} it work! but cmd screen is auto close. – salmorn Mar 01 '17 at 21:56
