Java and setting a variable equal to an array

How do you set a variable equal to an array in Java. For example I have a class for input and a class for calculations which hold arrays. when I accept the user input from the input class how do I pass that variable into the array of my calculation clas开发者_JS百科s?

You should look into varargs. Code sample below:

public MyClass method(String ...arg);

You can call this method as :

method("test1", "test2", "test3");   // with arbitrary number of values.

Or as

String[] test = something;
method(test);

Unless you have strict requirements to use arrays, you should probably be using a Collection, like a List.

For example, if you're trying to manage an array of ints, you could instead do:

List<int> intList = new ArrayList<int>();

Then, if you really need the data in the form of an array, you can do:

intList.toArray();

Which would return an array holding the integer values in your list. Lists are easier to read and use.
