java - How find common number from two textview -

i have 2 textview , 2 buttons.

textview tv1,tv2; button yes,no; 

now

   tv1.settext("1 2 3 4 5");    tv2.settext("3 4 5 6 7"); 

and

   yes.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {             //here want show common number (3,4,5)              }         });      no.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {      //here want show number  no matched in both textview             }         });  

now question when click on yes show (3,4,5 because common) tv1 , when click on no show (1,2,6,7) tv1.

i can set text if have more numbers.

you may put number array or list easy find common number.

public list<integer> findcommonelement(int[] a, int[] b) {      list<integer> commonelements = new arraylist<integer>();      for(int = 0; < a.length ;i++) {         for(int j = 0; j< b.length ; j++) {             if(a[i] == b[j]) {                 //check if list contains common element                 if(!commonelements.contains(a[i])) {                     //add common element list                     commonelements.add(a[i]);                 }             }         }     }     return commonelements; } 

and may check using:

int myarray[] = { 2, 2, 7, 7, 2, 1, 5, 4, 5, 1, 1 }; int myarray2[] = { 2, 3, 4, 7, 10 };  log.d("common", string.valueof(findcommonelement(myarray, myarray2)));
