Hello All,
I have written a simple program to execute "ls" through java. But it
isnt working. Can any one point out the error?
class ExecDemo{
public static void main(String args[]){
Runtime r=Runtime.getRuntime();
Process p=null;
String cmd{}={"ls"};
try{
p=r.exec(cmd);
}catch(Exception e){
System.out.println(error+cmd[0]);
}
}
}
When I run it, the program does not do "ls" and silently quits. When I
changed "ls" with "vi ExecDemo.java" it said error vi ExecDemo.java.
In the book in which this program is given the command for String cmd[]
is as:
String cmd[]={"ls","/java/src/java/lang/Runtime.java"};
But, I am not able to locate Runtime.java anywhere on my machine..
Please point out the correct procedure to run the above code.
Thanks
Alpesh
