java - Why do the same values get put into my LinkedHashMap Array? -

i using linkedhashmap array. way 'put' , 'get' values?

in linkedhashmap<integer, integer[]> have:

key 1 -> integer array {5,6,2,4}

key 2 -> integer array, {7,2,6,1}

.... goes on

here code snippet use store values

// has store data order received linkedhashmap<integer, integer[]> hparamval = new linkedhashmap<integer, integer[]>();  // temprory integer array store number received integer[] iarrynoofparam = new integer[inoofscalar];  (irow = 0; irow < inoofblocks; irow++) {    (icol = 0; icol < inoofarrval; icol++) {      bbuffgenstr = arrays.copyofrange(buffrecv, istartloc, ioffset);     gendataval oparamval = datastruct.readgenvalue(bbuffgenstr);     bbuff4genstr = oparamval.getvalue();     // store integer array received     iarrynoofparam[icol] = bytebuffer.wrap(bbuff4genstr)         .order(byteorder.little_endian).getint();      istartloc = ioffset;   }    // store array of integer every key   hparamval.put(irow, iarrynoofparam); } 

is hparamval.put correct?

the following code data linkedhashmap

for (integer key : hloadsurveyparam.keyset()) {   system.out.println(" key  # " + key);    (icol = 0; icol < inoofscalar; icol++) {     system.out.println(hparamval.get(key)[icol]);   } } 

is hparamval.get correct of above?

i getting same value, because last values stored in iarrynoofparam keys!

bring line integer[] iarrynoofparam = new integer[inoofscalar]; for loop.

when call put() storing reference of array in linkedhashmap. since storing same reference every time, see values set last. want store new array reference every key in linkedhashmap.
