how to run a command at terminal from java program?

You need to run it using bash executable like this:

Runtime.getRuntime().exec("/bin/bash -c your_command");

Update: As suggested by xav, it is advisable to use ProcessBuilder instead:

String[] args = new String[] {"/bin/bash", "-c", "your_command", "with", "args"};
Process proc = new ProcessBuilder(args).start();

I vote for Karthik T's answer. you don't need to open a terminal to run commands.

For example,

// file: RunShellCommandFromJava.java
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class RunShellCommandFromJava {

    public static void main(String[] args) {

        String command = "ping -c 3 www.google.com";

        Process proc = Runtime.getRuntime().exec(command);

        // Read the output

        BufferedReader reader =  
              new BufferedReader(new InputStreamReader(proc.getInputStream()));

        String line = "";
        while((line = reader.readLine()) != null) {
            System.out.print(line + "\n");
        }

        proc.waitFor();   

    }
}

The output:

$ javac RunShellCommandFromJava.java
$ java RunShellCommandFromJava

Can you create games that run in the terminal or command line that are like pong?

Oh, sure, just not easily at all. You'd need something like ncurses to do this for just any terminal. That's not a beginner's library at all. It's misleadingly difficult. The general idea is to have a single main loop that refreshes the game state (and thus what is drawn) at frequent intervals. You'd have to capture the keyboard inputs (which ncurses can do) to detect how to move the player's paddle. The physics of pong are very simple, so the main difficulty is figuring out how to draw things. More on reddit.com
