API使用不当:调用的方法需要数组作为参数,但错误地传入了一个ArrayList对象。 类型不匹配:在编写代码时,没有注意到方法签名中参数类型的具体要求,导致类型不匹配。 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>

const arrayList = [1, 3]; You can use the filter method to create a new array that includes only the rows from the table where the id is in the arrayList: const filteredTable = table.filter(row => arrayList.includes(row.id)); ...
For such arrays it is still possible to place the space for the array in the stack frame of its subroutine, but an extra level of indirection is required (see Figure 7.6). In order to ensure that every local object can be found using a known offset from the frame pointer, we divide ...
Initialization When performing initialization for an array, it is required to specify the size of the array. It is not necessary to mention the size of an ArrayList. Performance Arrays are faster ArrayList is slower Generic Type An array can store primitive data as well as objects, but it can...

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: ...
