Android String Edit and Array's value positioning

Question

I have two problem. Please try to solve...

No 1. Suppose I have two string:-

String one = "Android is awesome";
String two = "Android is";

Now my question is, can I get awesome by comparing those two string like we do with int.

int abc = 50;
int def = 35;
int ghi = abc - def;

output :-

ghi = 15;

So, this is what we do basically with int, long, double... Is it possible also with String?

No 2. Now, suppose again I have a string-array

ArrayList<String> list = new Arraylist()<>;
list.add("beautiful");
list.add("awesome");
list.add("cool");

Now, if string-comparing is possible, then suppose I have got a new String three from comparing one and two.

So, here,

String three = "awesome";

Now, again, I am using if-statement

if(list.contains("awesome")){

**Problem here starts. See the commented texts**

//Here if **awesome** is found in **list**, so can I get the position of **awesome** in the **list**?
}

Forgive me for a big and rough question. Please help me. I am really so sad with this problem.

I don't understand what you are trying to achieve. But if you want to get position of certain element in list you can use indexOf method of ArrayList docs.oracle.com/javase/7/docs/api/java/util/… — Pragnani Kinnera

i don't understand your first question. What is suppose to be the result of "Android is awesome" - "Android is" ? Awesome ? Or another thing ? For the second question, use methods contains and indexOf of Arralist — marco

If you want the remaining string by comparing two strings, try the following

String one = "Android is awesome";
String two = "Android is";
    if(one.contains(two)){
        Log.i("remaining string ",one.split(two)[0].replace(" ",""));
        Log.i("remaining string ",one.split(two)[1].replace(" ",""));
    }else{
        Log.i("remaining string ","");
    }

Then use the remaining string to find the index from list.Try the following ,

  list.indexOf(remainingstring);

Glad it helps. But check for the splitted array. You may get the remaining string at 0 or 1 st position. So be careful with that.
