Execute a command without thread

Question

Hi....i have to execute a command in DOS and i'm using runtime java class with its method exec(). The process works perfectly but in my code i have to execute that command without a thread because the successive operations will work only if the command terminated correctly. What can i do to resolve it?

Answer 1

String cmd = input.getTxtDb2Cmd();
Process p = Runtime.getRuntime().exec(cmd);
int r = p.waitFor();
if (r != 0)
throw new RuntimeException("db2 command failed");
i've to invoke a db2 command that import a txt file in a db table. After this code i've some operations that works with this table so i've to terminate this import before execute other functions.
