public class SimpleProcess
extends java.lang.Process
The example below demonstrates the use of this class.
class ExecuteProcess { public static void main( String args[] ) { if ( args.length > 0 ) { String processName = args[ 0 ]; try { SimpleProcess process = new SimpleProcess( Runtime.getRuntime.exec( processName ) ); ); int exitStatus = process.waitFor(); System.out.println( "The process ran successfully" + " with an exit status of " + exitStatus + "." ); } catch ( Exception e ) { System.out.println( "The process was not successful. " + " Reason: " + e.getMessage() ); } } else { System.err.println( "Please specify a command" ); } } }
