Iterating inside a java stream filter

return Arrays.stream(partNumbers.get())
.filter(partNumber -> Objects.nonNull(partNumber.getDescription()))
.filter(partNumber -> partNumber.getDescription().toLowerCase().contains(rateAbbr.toLowerCase()))
.findFirst();
The above code would try to find a partNumber from a list of partNumbers where partNumber's description contains a 'rateAbbr'.
This code worked till 'rateAbbr' was a String but now it is changed to a list of rateAbbrs and I need to find a part number whose description contains any of the rateAbbrs. I tried it with streams and no luck yet. any help is appreciated.

just create a private boolean function that iterates over the list and checks if there is match, then call it inside filter method.

Appium : Verify relative element presence

Can you give a suggestion(please see pic) how can I check if selectIndicator is present on one block then I should choose another one. I know how to check if that element isPresent on whole page, but I need to find if it present on particular element. In my example I have Living Room chosen, and I need to check if DVR not chosen -choose that one. Any idea how can I do it? I was trying to check this way, but no luck:
WebElement element= driver.findElementByAccessibilityId("First element").findElementByAccessibilityId("Second element");

If I am not getting you wrong you want to implement a self defined data structure for an appropriate solution. That could be something similar to this :
public class DVRList {
//declare components required to comprise one item
private String dvrOptionText ;
private boolean dvrOptionCheck ;
// implement setter..getter for these two
}
...in some method set the value using the logic
DVRList dvrlist = new DVRList();
WebElement parentOfBoth = driver.findElement(By.xpath("
//android.widget.RelativeLayout[1]/android.widget.R‌​elativeLayout[1]");
String text = parentOfBoth.findElementByAccessibilityId("First element").getText();
dvrlist.setdvrOptionText(text);
if(isElement(parenOfBoth.findElementByAccessibilityId("Second element"))
dvrlist.setdvrOptionCheck(true);
else dvrlist.setdvrOptionCheck(false);
and thereafter you can use these parameters accordingly.
Note : Parameters and approach are generalised and should be modified for serving the exact purpose.

Howto check if a TreeMap contains a specific object?

In an application I have this TreeMap object:
treePath = new TreeMap<String, DLFolder>();
The first String parameter should be the key and the DLFolder is the value.
Ok the DLFolder object have this method dlFolder.getPath() that return a String
So I want to know if the treePath object contains a DLFolder object having a specific path value
Can I do this thing?
Tnx

for (DLFolder dlf : treePath.values()) {
if ("A SPECIFIC PATH".equals(dlf.getPath()) {
// do someting with the dlf
}

In Java 8 this is rather straightforward.
treePath.values().anyMatch(dlf -> dlf.getPath().equals(specificValue))

You can loop through the values of the TreeMap:
for (DLFoder folder : treePath.values())
if (folder.getPath().equals(somePathValue))
// path found!

If the map's key is also the value stored in dlFolder.getPath(), then yes, you can just call treePath.contains("Value");.
Other options include:
Iterating over treePath's values either using an iterator, an enhanced for loop, or the Java 8 streams.
Creating another map to map the same DLFolder objects, but by path.

How to access the values from strings.xml dynamically?

What I want to do is to get a specific text from strings.xml dynamically. I think it will involve to access an object variable dynamically.
There will be a function like:
public void getDynamicString(int level) {
text.setText(R.string.levelText_+level);
}
And in strings.xml there will be <string name="levelText_5">Text level 5</string>
I would rather not create a list with all the text resources. Can one do this in Java/Android.

Use the method getIdentifier(name, defType, defPackage) of the Resources class to get the id of a resource by name. Then you can do a normal getString(id) from the same class.
EDIT: a bit of Googling revealed this: this. You can find sample usage there.

Try: getResources().getString(R.id.stringId).

You should look at using getIdentifier(String, String, String) of the Resources class.

All you have to do is call
this.getString(R.string.levelText_5)
If your in an area of the program in which you have access to a Context or Application, such as a ListAdapter call:
context.getString(R.string.levelText_5)
or
application.getString(R.string.levelText_5)
if you have no access to the context or application then call:
getResources().getString(R.String.levelText_5);
To do it dynamically call:
String name = "levelText_"+level;
int id = getIdentifier(name, "string", "com.test.mypackage");
getResources().getString(id);

I had the same problem and I fixed it using this
okey , whenever you want to access a string from strings.xml dynamically and what i mean by that is to avoid using getResources().getString(R.id.stringId) ,you create a string in which you can manipulate dynamically however you want in our case uriq ("stupid variable name") and then you create resource object which is in my example level_res and initialize it then you use this method called getIdentifier() which accepts your dynamic string as a parameter ,now u simply pass your ressource to the method getstring(mysttring)
String uriq="level"+level_num;
level_res=getResources();
int mystring=getResources().getIdentifier(uriq,"string",getPackageName());
String level=level_res.getString(mystring);

Look for string in arraylist element and pair it with specific image

Im trying to do a MVC application with Model , JSP and Servlet.
From my Model I get an arrayList:
ArrayList<String> myArrayList = new ArrayList<String>();
Each element look like this example: 96125;www.qwerty.com
Lets say I have a image named: www.qwerty.com.png
I want to take myArrayList pass it from my servlet to the jsp. So lets say I call for myArrayList[0] and the first element is 96125;www.qwerty.com I want it to show the image www.qwerty.com.png in my JSP instead of the actual element.
How can I solve this?

For getting just the image name, you can use split method of String Class:
myArrayList[0].split(";")[1]
