Question

I’m Working on Java, Following is my code snippet,

ProcessBuilder pb = new ProcessBuilder();
Map<String, String> envMap = pb.environment();
envMap.put("Dumyy", "myValue");
Process p = envMap.start();

With above i got following error:

error: cannot find symbol Process p = envMap.start();

How to resolve this error?

Answer 1

envMap is a map and it does not have a method start.
Your code should be:

ProcessBuilder pb = new ProcessBuilder();
Map<String, String> envMap = pb.environment();
envMap.put("Dumyy", "myValue");
Process p = pb.start();
