How to declare a static string array in Java?

Question: I want to declare a static string array using an array in .

How to declare a static string array in Java?

I have a Java program that has two functions and a static string array. Can anybody tell me how to declare a static string array in java?

To initialise an array at construction time you can specify a list values in curly braces:

private static final String[] STRING_ARRAY = ;

In my example I have assumed that you won’t want to change the instance of array and so have declared it final . You still would be able to update individual entries like so:

But you won’t be able to replace the array with a different one completely. If the values are going to change a lot — especially if the number of values are going to change — then it may be worth considering using List instead.

public static String[] stringArray = new String[size]; // give some "size"

public static String[] stringArray = ;

public static String[] array =;

Java — static object array, For that, each object of Point class must associated to an object of Array class. But, the array p you are creating is in static context. So, you have to either make the Point class a static one or make the array p a non-static one. 3. parseInt is not a method of String class. parseInt is a static method of Integer …

How to create a static array of strings?

Note This question contains syntax that predates Rust 1.0. The code is invalid, but the concepts are still relevant.

How do you create a global static array of strings in Rust?

For integers, this compiles:

static ONE:u8 = 1; static TWO:u8 = 2; static ONETWO:[&'static u8, ..2] = [&ONE, &TWO];

But I can’t get something similar for strings to compile:

static STRHELLO:&'static str = "Hello"; static STRWORLD:&'static str = "World"; static ARR:[&'static str, ..2] = [STRHELLO,STRWORLD]; // Error: Cannot refer to the interior of another static

This is a stable alternative for Rust 1.0 and every subsequent version:

There are two related concepts and keywords in Rust: const and static:

For most use cases, including this one, const is more appropriate, since mutation is not allowed, and the compiler may inline const items.

const STRHELLO:&'static str = "Hello"; const STRWORLD:&'static str = "World"; const ARR:[&'static str, ..2] = [STRHELLO,STRWORLD];

Note, there is some out-of-date documentation out there that doesn’t mention the newer const, including Rust by Example.

Another way to do it nowadays is:

const A: &'static str = "Apples"; const B: &'static str = "Oranges"; const AB: [&'static str; 2] = [A, B]; // or ["Apples", "Oranges"]

Just used this to allocate a small POC level for a game in Rust

And loaded using the following function

How to initialize a static string array in solidity?, You can use the string keyword, or in your case, a fixed-sized (3) array of strings. pragma solidity ^0.8.4; contract MyContract < // string in storage string [3] verifiedResult = ["verified successfully", "verified failed", "not clear"]; function foo () external < // string in memory string [3] memory anotherStringArray = ["verified

Static constant string array, how to use

How can I initialize and use an static constant string array? I made an example, the header:

const static string validFileTypesToSendToClient[];

const string Settings::validFileTypesToSendToClient[] = ;

This works, but how can I use this? For example in this case:

string fileTypesToAllow[] = Settings::validFileTypesToSendToClient;

Initialization with ‘’ expected for aggregate object.

So, how can I use a static constant array of string in a proper way? I already found this: Initializing a static const array of const strings in C++ but they don’t describe how to use it.

Built-in array assignment doesn’t exist in C++. You can, however, do this:

#include #include std::array string_array = < "foo", "bar", "baz", >; int main() < std::arraysecond_string_array = string_array; >

It’s C++11, but it is supported by almost every compiler nowadays. (It seems questionable why you would like to copy such an array in the first place btw. Also, this is one of the cases were I’d consider using const char*, even though you can definitely forget the assignment with that one.)

string fileTypesToAllow[] = Settings::validFileTypesToSendToClient;

is wrong. C/C++ doesn’t allow array assignment. You may assign an array to pointer, but another array.

In the following line, you are declaring a new array of strings, and trying to initialize it with another array. This is not allowed in C++.

string fileTypesToAllow[] = Settings::validFileTypesToSendToClient;

What you should do instead is to declare the array, and then copy the values over:

const int size = 3; // Same as the size of the Settings::validFileTypesToSendToClient array string fileTypesToAllow[size]; for(int i = 0; i

You can’t assign an array to another array, you have to copy element one by one:

 string fileTypesToAllow[3]; for(int i=0; i

To access array, you could do like this:

Could just use vector instead of array or std::array

struct Settings < const static std::vectorvalidFileTypesToSendToClient; static std::vector makeData() < std::vectorv; v.push_back("html"); v.push_back("css"); v.push_back("js"); return v; > >;

const std::vector Settings::validFileTypesToSendToClient = Settings::makeData();

Now you can copy validFileTypesToSendToClient easily:

int main() < std::vectorfileTypesToAllow = validFileTypesToSendToClient; return 0; >

Is there a way to define a static String array from strings.xml

I want to declare a static string array using an array in strings.xml .

private static final String[] tip_types = getResources().getStringArray(R.array.tip_types_array);

but you cannot use getResources() ‘in a static context’. Is there a way to do this or must I not use a static variable?

private final String[] tip_types = getResources().getStringArray(R.array.tip_types_array);

works, but then the declared array is not static.

To fetch resources (including strings) you always need a context. When you create a static field, even within an Activity, you cannot access the instance fields and therefore there’s no context available.

You have two options to solve the problem:

Method 1
You can create an Application class that stores the application context in a static field upon creation and get your string array using the application context.

private final static String[] tip_types = YourApplicationClass.getAppContext().getResources().getStringArray(R.array.tip_types_array);

Method 2
You can create a getter for your static variable where you pass a context. Like a singleton you check if the array is already resolved, and return it right away or fetch is using the supplied context. This has the advantage of lazy initialisation, the array is only created when it’s actually needed.

private static String[] tip_types; private static String[] getTipTypes(Context context) < if(tip_types == null) < tip_types = context.getResources().getStringArray(R.array.tip_types_array); >return tip_types; >

The first one, you need declare a NfcApplication custom class which extend from Application class:

public final class NfcApplication extends Application < private static NfcApplication sApplication; public static NfcApplication getInstance() < return sApplication; >@Override public void onCreate() < super.onCreate(); sApplication = this; >@Override public void onTerminate() < super.onTerminate(); sApplication = null; >>

The second one, then you can call the context by this way

private static final String[] ARRAY_LIST = NfcApplication.getInstance().getResources().getStringArray(R.array.label_unit_array_str);

Passing array of String as static param in Struts 2, You have also include setParams(Map params) in the action to the interceptor set the values of the params. Use different keys name1, name2, name3 in your case to retrieve the values of the map. You can also try overwrite property (not documented) for the static params to not overwrite the value with the same …
