Question

Is there a java equivalent of the python eval function?

This would be a function which takes an arbitrary string and attempts to execute it in the current context.

Answer 1

It may be that you wish to execute a DOS or unix command in the workflow of Java program execution...

String command = "cmd /c dir /s";
String homeDir = "C:\\WINDOWS";
Process process = Runtime.getRuntime().exec(command + " " + homeDir);

And may be you wish to process the output...

final InputStream in = process.getInputStream();
int ch;
while((ch = in.read()) != -1) {
   System.out.print((char)ch);
}

Close code with try, catch
