bjr svp aidez moi à fusionner ces deux codes en une seule pour que je puisse tester. En faite ces deux codes sources vont me permettre de guider mon robot dans des lieux différents dont les noms se trouvent sur ce fichier excel. merci pour votre aide.
 
 
 
   1er code source:
 
package fr.icam.bb8;
import java.io.InputStream;
import java.util.Scanner;
 
public class UnitR {
 
 long[] systems;
 String[] namings;
 long[][] navmaps;
 
 void init() {
  systems = new long[359];
  namings = new String[359];
  navmaps = new long[359][359];
 }
 
 int read(String name, int index) throws Exception {
  InputStream input = UnitR.class.getResourceAsStream("/" + (name == null ? "" : name + "-" ) + "systems.csv" );
  Scanner scanner = new Scanner(input);
  int i = index;
  while (scanner.hasNextLine()) {
   String line = scanner.nextLine();
   String[] items = line.split("," );
   systems[i] = Long.valueOf(items[0]).longValue();
   namings[i] = items[1];
   i++;
  }
  scanner.close();
  input.close();
  return i;
 }
 
 int index(long id) {
  for (int i = 0; i < systems.length; i++) {
   if (systems[i] == id) {
    return i;
   }
  }
  return -1;
 }
 
 void load(String name) throws Exception {
  InputStream input = UnitR.class.getResourceAsStream("/" + (name == null ? "" : name + "-" ) + "navmaps.csv" );
  Scanner scanner = new Scanner(input);
  while (scanner.hasNextLine()) {
   String line = scanner.nextLine();
   String[] items = line.split("," );
   long source = Long.valueOf(items[0]).longValue();
   long target = Long.valueOf(items[1]).longValue();
   long effort = Long.valueOf(items[2]).longValue();
   int i = index(source);
   int j = index(target);
   if (i == -1 || j == -1) {
    System.err.println("skiping " + source + " -> " + target + " (" + effort + " )" );
   } else {
    navmaps[i][j] = effort;
    navmaps[j][i] = effort;
   }
  }
  scanner.close();
  input.close();
 }
 
 void setup(String name) throws Exception {
  init();
  read(name, 0);
  load(name);  
 }
 
 int index(String name) {
  for (int i = 0; i < namings.length; i++) {
   String source = namings[i];
   if (source == null) {
    continue;
   } else if (source.equalsIgnoreCase(name)) {
    return i;
   }
  }
  return -1;
 }
 
 int ask(Scanner scanner, String text) {
  int s = -1;
  do {
   System.out.print(text);
   String source = scanner.nextLine();
   s = index(source);
   if (s == -1) {
    System.out.println("sorry, i don't know " + source + "." );
   }
  } while (s == -1);
  return s;
 }
 
 void route(Scanner scanner) {
  int s = ask(scanner, "from? " );
  int t = ask(scanner, "to? " );
  String src = namings[s];
  String tgt = namings[t];
  long duration = navmaps[s][t];
  if (duration == 0) {
   System.out.println("there is no direct route from " + src + " to " + tgt + "." );
  } else {
   System.out.println("the direct route from " + src + " to " + tgt + " takes " + duration + "ms." );
  }
 }
 
 void list(Scanner scanner) {
  System.out.print("filtering on: " );
  String filter = scanner.nextLine();
  for (int i = 0; i < namings.length; i++) {
   if (namings[i] == null) {
    continue;
   } else {
    long id = systems[i];
    String pattern = namings[i].toLowerCase();
    String prefix = filter.toLowerCase();
    if (pattern.startsWith(prefix)) {
     System.out.println("  - " + namings[i] + " (" + id + " )" );
     
    }    
   }
  }
 }
 
 void loop(String name) {
  System.out.println("hello! my name is " + name + " and i'm ready." );
  Scanner scanner = new Scanner(System.in);
  boolean exit = false;
  while (exit == false) {
   System.out.print("what are you asking for? " );
   String line  = scanner.nextLine();
   if (line.equalsIgnoreCase("exit" )) {
    exit = true;
   } else if (line.equalsIgnoreCase("list" )) {
    list(scanner);
   } else if (line.equalsIgnoreCase("route" )) {
    route(scanner);
   } else {
    System.out.println("sorry, i don't understand your request." );
   }
  }
  System.out.println("bye!" );
  scanner.close();
 }
 
 void process(String name) throws Exception {
  setup(name);
  loop(name);
 }
 
 public static void main(String[] arguments) throws Exception {
  UnitR unit = new UnitR();
  unit.process("bb8" );
 }
 
}
 
 
 
 
        2e code source:
package fr.icam.bb8;
 
public class UnitBB extends UnitR {
 
 void setup(String... names) throws Exception {
  /* TODO */  
 }
 
 void process(String name, String... names) throws Exception {
  setup(names);
  loop(name);
 }
 
 public static void main(String[] arguments) throws Exception {
  UnitBB unit = new UnitBB();
  unit.process("BB-8", "r2d2", "bb8" );
 }
 
}
 
 

Il suffirai de supprimer un des deux main. Logiquement, je pense que c'est celui du 1er code à supprimer car le deuxième code est un cas étendu du premier.
