I need to update an ArrayList if object exists based on id in the object.
Thanks in Advance
Arraylist have a mArrayList.contains() method and than you can get the element index by looping and update item if you are requesting to update in the ArrayList and not somewhere else :
mArrayList.set(yourdesiredIndexOfTypeInt , desiredValueOrObject);

If I were to print
System.out.println(-Math.abs(-14));
would it print -14 or would it disregard the negative sign on the outside of the Math.abs code?
You will get -14. Please go try your code first to see its behaviour

I'm trying to insert this values to a new table but eclipse doesn't read this query:
INSERT INTO my-list SELECT * FROM cars WHERE color='RED'
Use executeUpdate() Or execute() to issue data manipulation statements. executeQuery() is only meant for SELECT queries.

I have a some trouble about my own simple android project. I save data pair (key-value), and I dont want to save same data. ( for example: I save the data "Car"- "Blue" once. and then application can not permisson save again same the data.) I wrote already update method but I couldnt use for search & control data repetition. How can I solve ?
Make the combination of the two columns a Primary Key
You can also use if else block along with SELECT statement to validate inputs.

I used microsoft.exchange.webservices.data.core.service.item.Item;
in microsoft.exchange.webservices.data.core.ExchangeService.
Use java.util.Set clas instead of list.
Set items = new HashSet<Item>();
Set is the collection of unique values.
