java - Return 2 integers in a int function -

-

i have 2 classes.

in first class integers low , high needed.

in second class want declare , change low , high.

public class displaymessageactivity extends actionbaractivity {      int low = 0;     int high = 101;

this works fine - after following function run through, integers didn't change.

public int close (view v) {      edittext low2 = (edittext) findviewbyid(r.id.edittext2);     edittext high2 = (edittext) findviewbyid(r.id.edittext3);      int low = integer.parseint(low2.gettext().tostring());     int high = integer.parseint(high2.gettext().tostring());     high ++;      toast.maketext(getapplicationcontext(), "low: " + low +" high: "+high, toast.length_short).show();     if (low > high) { //you can ignore         alertdialog.builder builder = new alertdialog.builder(this);         builder.settitle("false numbers");         builder.setmessage("you set lower number higher higher one.");         builder.show();     } else {         this.finish();     }      return low; //i want return low , high - command not change low or high! }

edited code: 

public class highandlow{     int high= 0;     int low = 101; }    public int[] close(view v){       edittext low2 = (edittext) findviewbyid(r.id.edittext2);     edittext high2 = (edittext) findviewbyid(r.id.edittext3);          low = integer.parseint(low2.gettext().tostring()); //cant find low         high = integer.parseint(high2.gettext().tostring()); //cant find high         high ++;      toast.maketext(getapplicationcontext(), "low: " + low +" high: "+high,             toast.length_short).show();         if (low > high) {         alertdialog.builder builder = new alertdialog.builder(this);         builder.settitle("false numbers");         builder.setmessage("you set lower number higher higher one.");         builder.show();     }         else{              this.finish();         }         return highandlow; //dont work   }

why not create high , low integers properties of class? implement you're usual getters/setters. set them via close method, , them second class when needed first instantiated class.
