Getting methods to work in a simple Java program -

i've got of program working apart few bits aren't, i'm new java it's not obvious i'm meant do.

here methods:

public string getinventorycode() {     return inventorycode; }  public int getquantityinstock() {     return quantityinstock; }  public int getdailydemand() {     return dailydemand; }  public int getreorder() {     return reorder; }  public int getleadtime()   {       return leadtime; }  public int newdeliveryin(int newdeli) {     quantityinstock += reorder;      return newdeli; } 

here main code:

stockitem item_1  = new stockitem("a654y", 1000, 50, 500, 13);  int quantityin = item_1.getquantityinstock();  (int n = 1; n <=50 ; n++) {     quantityin -= item_1.getdailydemand();      system.out.print(n + "\t");     system.out.println(quantityin);      if (n % item_1.getleadtime() == 1 ){          system.out.println("batch ordered");     }      else if (n % item_1.getleadtime() == 0){          quantityin += item_1.getreorder();         system.out.println("batch received");      }     } 

it's simple stock control program counts days 50, each day reducing amount of stock (quantityinstock) x amount (dailydemand) , when gets day (for instance every 10th day (haven't yet made method this, not sure how go it) order more stock (reorder) delivered , added current stock after amount of days after order (leadtime). think i'm there, last bit can't work out.

this output i'm getting @ moment:

 1  950  batch ordered  2  900  3  850  4  800  5  750  6  700  7  650  8  600  9  550  10 500  11 450  12 400  13 350  batch received  14 800  batch ordered  15 750  16 700  17 650  18 600  19 550  20 500  21 450  22 400  23 350  24 300  25 250  26 200  batch received  27 650  batch ordered  ... 

i "batch ordered, batch received" go alongside relevant day (3rd column) instead of under, can't work out how.

any great! thanks.

i printing console after have run through 2 if statements determining weather or not show batch received or batch ordered.

so change for loop this

for (int n = 1; n <=50 ; n++) {     string out = "";      quantityin -= item_1.getdailydemand();      out += n;     out += " " + quantityin;      if (n % item_1.getleadtime() == 1 ){          out += " batch ordered";     }      else if (n % item_1.getleadtime() == 0){          quantityin += item_1.getreorder();         out += " batch received";      }      system.out.println(out);  } 

i created variable named out. keep adding content variable , @ end of loop prints out. way not have worry printing console in fancy ways.

update

here solution stock problem.

int reorderthreshold = 10; stockitem item_1  = new stockitem("a654y", 1000, 50, 500, 13);  int ordertraveltime = 0; boolean orderintravel = false;  for(int = 0; < 50; i++){   //do other things, printing out daily demand ,   if(orderintravel && ordertraveltime < item_1.getleadtime()){//if order has been ordered , has not arrived     ordertraveltime ++;   } else if(orderintravel && ordertraveltime >= item_1.getleadtime()){//if ordered , has arrived     ordertraveltime = 0;     orderintravel = false;      item_1.quantityinstock += item_1.getreorder();   }    if(item_1.getquantityinstock() < reorderthreshold){//if stock gets low, order     orderintravel = true;   } }
