F.A.Q. of Statistical Algorithms Importer (SAI), here are common mistakes we have found in Java Project.


Main Class

The first parameter of a Java process is the main class that will be executed. Please note the full package name must be entered as default value, for example:

  • org.d4science.projectx.XClass


How Use File Input

Add input file parameter in Java project:
File Input Parameter, SAI
Java source code in sample:
package org.myfactory.specialgroup;
 
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
 
/**
 * 
 * @author Giancarlo Panichi
 *
 */
public class FileConsumer {
 
	public static void main(String[] args) {
		try {
			Path fileInput=Paths.get(args[0]); //second parameter in the project
			Path fileOutput=Paths.get("output.txt");
			Files.copy(fileInput, fileOutput, StandardCopyOption.REPLACE_EXISTING);
 
		} catch (Throwable e) {
			System.out.println("Error in process: " + e.getLocalizedMessage());
			e.printStackTrace();
		}
	}
 
}
Java code in sample:

File:JavaBlackBox FileInputPrameter.zip

How Use Enumerates Input

Consider the Las Vegas algorithm:
Las Vegas Info, SAI
Indicates the java version
Las Vegas Interpreter, SAI


Indicates the I/O parameters:
Las Vegas Interpreter, SAI


Java source code in Las Vegas:
package org.myfactory.specialgroup;
 
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardOpenOption;
import java.util.function.ToIntFunction;
import java.util.stream.Stream;

			// 52
			factor = (int) (Math.random() * 52);
			if (factor > 26 || (bluff && factor > 13)) {
				winnings = beat * 52;
			} else {
				winnings = 0;
			}
			break;
		default:
			winnings = 0;
			break;
 
		}
 
		return winnings;
	}
 
	public static void main(String[] args) {

			init(args[0], args[1],args[2]);
			Integer winnings = 0;
 
			// read stream
			try (Stream<String> stream = Files.lines(betsFile)) {
				winnings = stream.mapToInt(play::applyAsInt).sum();
			} catch (IOException e) {
				System.out.println("Error reading the file: " + e.getLocalizedMessage());
				e.printStackTrace();
			}
 
			String result = "You Won: " + winnings;
 
			Path fileOutput = Paths.get("win.txt");
			Files.write(fileOutput, result.getBytes(), StandardOpenOption.CREATE);
 
		} catch (Throwable e) {
			System.out.println("Error in process: " + e.getLocalizedMessage());
