I need to define specific numbers out of an array of 52 numbers so I can assign them an image (yes I am creating an applet). I don't think that code is necessary for any of you to answer this question. Any help would be fantastic.

I'm not sure I understand what you're asking. You can set an item in an array this way:
myArray[4] = 52;
That would set array index #4 (remember it's zero based so it's actually the 5th item) to the value of 52. Is that what you're looking for?

I am trying to produce all permutations of an array of size N (i.e. N = 9) with possible elements Z (i.e. Z = [0,1,2,3,4])
Duplicates are allowed, but there needs to be at least one. I am able to write the algorithm to go through all possibilities but the minimum of at least one of each of Z is the part I'm having trouble with.
Looking to do this algorithm in java. Can someone help?

I have a list of strings in random format:
AppName-ver-1.1.0-data.exe
AppName-ver-1.1.1-secondData.exe
AppName-ver-1.2.0-data.exe
AppName-ver-1.2.1-data.exe
AppName-ver-1.2.3-data.exe
AnotherAppName-ver-1.0.0-data.exe
AnotherAppName-ver-1.0.0-secondData.exe
What would be an efficient way in java to find the closest value to string:
AppName-ver-1.2.4-data.exe
UPD: closest - by the naming not length so AppName-ver-1.2.3-data.exe is the expected result
To emphasize what commenters already pointed out:
If you define 'closest' to be the string length, then
AppName-ver-1.2.4-data.exe has the value 26, and
AppName-ver-1.1.0-data.exe
AppName-ver-1.2.0-data.exe
AppName-ver-1.2.1-data.exe
AppName-ver-1.2.3-data.exe
all resemble 26 as well so they are a direct match.
You could also define 'closest' to have the least Hamming Distance. This will give completely different results and AppName-ver-1.2.0-data.exe might win as it is just one bit off.

I tried it with Sieve Of Eratosthenes, but I quickly run into the problem that my boolean array can't go past Integer.MAX
How should I approach this problem?
Arrays
Use 2 or more dimensional maps. So converting long to two integers (for accessing the arrays) will be like this:
array[N / Integer.MAX_VALUE][N % Integer.MAX_VALUE] where N is long and array is the boolean array.

I have a list of users and they have status as attribute and I want
the users who have status 'disable' be at the end of the list. There are 4 types of status: 'disable', 'connect', 'notConnect', 'deleted'.
You can sort the list using a Comparator that evaluates "disable" as larger than any other status.
users.sort(Comparator.comparingInt(user -> "disable".equals(user.status) ? 1 : 0));
You can extend this solution by adding integer rankings for the other statuses as well.

I am currently writing a game in Java, where words in a string will have to be all changed to equal 5 characters a word.
eg. I am writing in Java
Iamwr iting inJav a
I wonder if anyone knows how I would do this?
First remove spaces between words.
Then split that resulting String to length with 5.
Add a space after every 5 character.
