将int []与一次Integer进行比较 [英] Compare int[] with once Integer

问题描述

我有的表[] 。我和每个用户进行循环操作：

I have table of int[]. I have for loop with every user and I do:

int[] ids = (values) 
for (User user : listAfterProcessing) {
    if (user.getId().equals(ids)) { ... } 
}

他们没有工作，虽然用户ID在这个表中...
感谢您的帮助：）

They didnt work, Although the user id is in this table... Thanks for help :)

推荐答案

您正在检查 getId（）的结果是否等于整个数组 ids ，默认情况下是与数组的哈希码的比较。

You are checking whether the result of getId() equals the entire array ids, which is by default a comparison to the array's hashcode.

根据这个问题的答案：如何将int []转换为List< Integer>在Java？

According to an answer in this question: How to convert int[] into List<Integer> in Java?

没有快速的转换方法。

there is no quick way to convert.

我在答案的第一个版本中建议的Arrays.asList（）解决方案在这里不起作用，抱歉。

The solution with Arrays.asList(), which I suggested in the first version of my answer, doesn't work here, sorry.
