how do i remove the contents of an array element such that if
hello(0) = "hello"
hello(1) = "hello123"
hello(2) = "hello123123"
i want the result to be
hello(0)="hello123"
hello(1) = "hello123123"
Using LINQ:
hello = hello.Skip(1).ToArray
You need to create a new array that's one element smaller than your source array, and copy the contents of the source array (excluding the first element) into the new array.

i have a list of objects called gobletinv that i want to add and remove objects from
right now to add a new object I've just done this
gobletinv(gobletpointer).mainstattype = MST.Text
gobletinv(gobletpointer).mainstatvalue = MSV.Text
gobletinv(gobletpointer).substat1type = ST1.Text
gobletinv(gobletpointer).substat1value = SV1.Text
gobletinv(gobletpointer).substat2type = ST2.Text
gobletinv(gobletpointer).substat2value = SV2.Text
gobletinv(gobletpointer).substat3type = ST3.Text
gobletinv(gobletpointer).substat3value = SV3.Text
gobletinv(gobletpointer).substat4type = ST4.Text
gobletinv(gobletpointer).substat4value = SV4.Text
gobletpointer += 1
i currently have no idea how i would remove an object from this list
Let's assume that the type your collection holds is called Stat. Let's also assume that gobletpointer is an Integer with an initial value of 0.
Each line where you are referencing the collection, you start it off with:
gobletinv(gobletpointer)
What this does is get the item from the collection at a given index.
So right now when you set the various property values to their respective TextBox value, you are overwriting the existing item in the collection.
If you wanted to add a new item to the collection, you would use the Add method (documentation). For example:
gobletinv.Add(New Stat() With {
mainstattype = MST.Text,
mainstatvalue = MSV.Text
substat1type = ST1.Text,
substat1value = SV1.Text,
substat2type = ST2.Text,
substat2value = SV2.Text,
substat3type = ST3.Text,
substat3value = SV3.Text,
substat4type = ST4.Text,
substat4value = SV4.Text
})
Now if you wanted to remove the object from the collection, it depends on how you want to remove it. But here is an example of leveraging the RemoveAt method (documentation) to remove the first record from the collection:
gobletinv.RemoveAt(0)
Update: This is a fiddle demonstrating how to add/remove items to the collection. https://dotnetfiddle.net/c0W6yS
Looking for a way to go to a few websites (10 sites) and grab a set of data, need a proper way to do since I am new to coding.
code:
WebUI.openBrowser('');
WebUI.navigateToUrl("www.site1.com");
WebUI.maximizeWindow();
String text1 = WebUI.getText(findTestObject("xpath"));
Do I need to do this for all the 10 websites?
Let's say you have the 10 URLs in an array. Create another empty array that will hold the text values:
WebUI.openBrowser('');
def mySites = ["www.site1.com", "www.site2.com", "www.site3.com", "www.site4.com", "www.site5.com", "www.site6.com", "www.site7.com", "www.site8.com", "www.site9.com", "www.site10.com"];
def myTexts = [];
Then loop your above code in a for loop, and add the text values to the array (note: xpath element name is the same for all the sites in this example, you should edit that according to your needs):
for(i=0; i<mySites.size; i++){
WebUI.navigateToUrl("www.site1.com");
WebUI.maximizeWindow();
myTexts << WebUI.getText(findTestObject("xpath"));
}
I am new to apache velocity, I want to create a subList Object from the List Objects which are coming from some service call in .vm file.
We need to render the list based on some logic in parts, for that we want to create sublist from list.
$table.getBooks() //contains all the Books objects
Below is the sample code which I tried but it did not work.
#set($segregatedList = [])
#set($size = $table.getLineItems().size())
#foreach($index in [0..$size-1])
#set($value = $index + 4)
#set($minimum = $math.min($nItems,$value))
$segregatedList.add($table.getBooks().subList($index,$minimum)))
$index += 4
#end
I executed the code, while rendering $segregatedList is coming as null.
I verified $table.getBooks() contains the Objects as when I am passing this,Objects are getting rendered successfully.
Can someone please tell what I am doing wrong or how can I create a sublist ?
First you are increment index with 4 and can cause an IndexOutOfBoundsException, so need to change until size-5 (and therefore remove math minimum check)
Second you are adding single Element instead of all Elements using addAll
Third your size check if on wrong parameter - should be on relevant $table.getBooks()
And last make sure your list have more than 5 elements
#set($segregatedList = [])
#set($size = $table.getBooks().size())
#foreach($index in [0..$size-5])
#set($value = $index + 4)
$segregatedList.addAll($table.getBooks().subList($index, $value)))
$index += 4
#end
I have an ArrayList ArrayList<String> externalDataList = new ArrayList<>(1600);and I would like to display in a textArea first 3 strings, but I can't succed:
Here is my code
textareaShowPreview.setPrefRowCount(3);
Iterator<String> it = externalDataList.iterator();
int tot = 0;
while(it.hasNext() && tot<3){
String element = it.next();
textareaShowPreview.setText(element + "\n");
System.out.println("elements are: " + element);
tot++;
}
The sout correctly print first 3 strings
element are: 23/05/2007 ,30.9455,31.2545,30.9091,30.9545,7518142
element are: 24/05/2007 ,30.6545,31.0909,30.5364,30.6909,12851606
element are: 25/05/2007 ,30.6636,30.8545,30.4818,30.8091,9392088
but in textArea I have only first one
How do I have to modify my code to show in textArea all three strings, one string per row?
Use appendText instead of setText here is a link.
The setText, delete the previous text and set the text you are giving to it. The append keep the current text in your text area.
Hope it helps!
I have a Java array such as:
String[] arr = new String[] {"123","doc","projectReport.doc"};
In my opinion the natural way to access would be:
#set($att_id = $arr[0])
#set($att_type = $arr[1])
#set($att_name = $arr[2])
But that it is not working. I have come with this workaround. But it a bit too much code for such an easy task.
#set($counter = 0)
#foreach($el in $arr)
#if($counter==0)
#set($att_id = $el)
#elseif($counter==1)
#set($att_type = $el)
#elseif($counter==2)
#set($att_name = $el)
#end
#set($counter = $counter + 1)
#end
Is there any other way?
You can use use Velocity 1.6: for an array named $array one can simply do $array.get($index).
In the upcoming Velocity 1.7, one will be able to do $array[$index] (as well as $list[$index] and $map[$key]).
You could wrap the array in a List using Arrays.asList(T... a). The new List object is backed by the original array so it doesn't wastefully allocate a copy. Even changes made to the new List will propagate back to the array.
Then you can use $list.get(int index) to get your objects out in Velocity.
If you need to get just one or two objects from an array, you can also use Array.get(Object array, int index)
to get an item from an array.
String[] arr = new String[] {"123", "doc", "projectReport.doc"};
In my opinion the natural way to access would be:
#set($att_id = $arr[0])
#set($att_type = $arr[1])
#set($att_name = $arr[2])
The value for this can be get by using $array.get("arr", 1) because there is no direct way to get the value from array like $att_id = $arr[0] in velocity.
Hope it works :)
Velocity 1.6
$myarray.isEmpty()
$myarray.size()
$myarray.get(2)
$myarray.set(1, 'test')
http://velocity.apache.org/engine/1.7/user-guide.html
there is an implicit counter $velocityCount which starts with value 1 so you do not have to create your own counter.
Brian's answer is indeed correct, although you might like to know that upcoming Velocity 1.6 has direct support for arrays; see the Velocity documentation for more information.
I ended up using the ListTool from the velocity-tools.jar. It has methods to access an array's elements and also get its size.
I has the same question and it got answered on another thread
#set ( $Page = $additionalParams.get('Page') )
#set ( $Pages = [] )
#if ( $Page != $null && $Page != "" )
#foreach($i in $Page.split(";"))
$Pages.add($i)
#end
#end
