Question

I want to read a String character by character which is already in an array.

String ss = "makassar";
String my_array[] = ss.split("");
for (int i = 1; i < ss.length()+1; i++) {
  if (my_array[i]=="m") {
     Toast toast = Toast.makeText(this, "Array is M", Toast.LENGTH_SHORT);
     toast.setGravity(Gravity.CENTER, 0, 0);
     toast.show();
     // Toast not show
  }
}

Toast is not getting displayed. Why? Any idea?

Answer 1

You should use equals() and not operator== to compare strings.

operator== checks for identity of objects [if the left and the right are the same object], while equals() checks equality [if the 2 strings equal each other].

Change this:

if (my_array[i]=="m")

to this:

if ("m".equals(my_array[i]))

Also, note that my_array[1] is the second element, and not the first, so you might want to start from i = 0 and not i = 1
