自动装箱/拆箱误解:误以为Integer对象数组和int类型数组可以自动转换,但实际上它们是不同的类型。 解决“array required, but arraylist<integer> found”错误的方法 解决这个问题的关键是将ArrayList<Integer>转换为数组。在Java中,可以通过ArrayList的toArray()方法来实现这一转换。 示例代码 以下是一个示例代码...
'ReDim' statements require a parenthesized list of the new bounds of each dimension of the array Reference required to assembly '<assemblyidentity>' containing type '<typename>', but a suitable reference could not be found due to ambiguity between projects '<projectname1>' and '<projectname2>...
A single-level nested field has a simple data structure that contains only one level. Single-level nested fields are suitable for scenarios in which data structures of multiple levels are not required but hierarchical structures are required. Example: ...

val str: java.util.stream.Stream[String] = ??? str.map[Int](_.toInt).toArray[Int]((_: Int) => Array.ofDim[Int](100000)) produces this great message on 2.12.7: type mismatch; found : Array[Int] required: Array[Int] Note: Int >: Int, but c...
However, if the number of required bit flags is unknown, is variable, or is greater than 32, use BitArray instead. BitArray is in the System.Collections namespace; BitVector32 is in the System.Collections.Specialized namespace. Elements in this collection can be accessed using an integer ...
=MAKEARRAY(4,3,Volunteerλ) I am told it is also possible to do this with 'thunks' (arrays placed within a Lambda function that may be expanded using an empty parameter string) but I have yet to make that work.

Simply surround a comma-separated list of values, instances, or literals with square brackets to create an array literal. You can use an array literal anywhere an instance of an ExpressibleByArrayLiteral type is expected: as a value assigned to a variable or constant, as a parameter to a ...
