people! so, i'm trying make battleship game (classic!) in java, basic array , method knowledge. created boolean board 2 dimensions place boats , here's code:
public void placerbateau(int x, int y, boolean dir, int longueur){ int abs = this.x; int ord = this.y; this.longueur = longueur; if(!tabplat[x][y]){ if(dir){ for(abs=ligne; ligne<ligne+this.longueur; abs++){ tabplat[abs][ord] = true; } } else { for(ord=colonne; colonne<colonne+this.longueur; ord++){ tabplat[abs][ord] = true; } } } } public class bataillenavale { public static void main(string [] args){ boolean [][] tabplat = { { false , false , false , false, false } , { false , false , false , false, false } , { false , false , false , false, false } , { false , false , false , false, false } , { false , false , false , false, false } , { false , false , false , false, false } }; plateau plat1 = new plateau(tabplat); plat1.placerbateau(2, 2, true, 2); plat1.tir(2, 2); system.out.println(plat1.tostring()); } basically, place boat, want cycle, , make true (change initial value) every cell within interval defined in statement. this:
exception in thread "main" java.lang.arrayindexoutofboundsexception: 6 @ plateau.placerbateau(plateau.java:39) @ bataillenavale.main(bataillenavale.java:6) which refers following line of code:
tabplat[abs][ord] = true; i understand stands for, don't how can have problem this.
ps - i'm sorry english.
the error here:
ligne<ligne+this.longueur you never change ligne or longueur goes on until reaches beyond array.
same colonne<colonne+this.longueur
