Java中两个大小不相同的数组列表如何比较大小和打印差异

如何解决Java中两个大小不相同的数组列表如何比较大小和打印差异

我在下面的程序中使用了两个比较两个数组列表的方法，但是我不想错过当两个数组列表的大小相同但包含不同值的情况。下面的代码也可以最小化。

ArrayList<String> firstList = new ArrayList<String> ( Arrays.asList("Cake","pizza","pasta") );
ArrayList<String> secondList = new ArrayList<String> ( Arrays.asList("Chocolate","fruits","pancake"));

if (!firstList.equals(secondList)) {
    if (firstList.size() > secondList.size()) {
        firstList.removeAll(secondList);
        SOP("Differance" + firstList+ "---------Total Number of Group mismatch----------"+ firstList.size());
    } else if (firstList.size() < secondList.size()) {
        secondList.removeAll(firstList);
        SOP("Differance" + secondList+ "---------Total Number of Group mismatch----------" + secondList.size());
    }
} else {
    SOP("Both are same");
}

解决方法

如果您要使用第三方实用程序，则可以直接使用

System.out.println(CollectionUtils.disjunction(firstList,secondList));

为最大限度地减少简单性，请使用下面的第三个列表

public static void main(String[] args) {
        ArrayList<String> firstList = new ArrayList<String> ( Arrays.asList("Cake","pizza","pasta","fruits") );
        ArrayList<String> secondList = new ArrayList<String> ( Arrays.asList("Chocolate","fruits","pancake"));         
        List<String> result = new ArrayList<String>();
        add(secondList,result);
        add(firstList,result);
        System.out.println(result);
    }

    public static void add(ArrayList<String> list,List<String> result) {
        for (String string : list) {
            if(result.contains(string)) {
                result.remove(string);
            }else {
                result.add(string);
            }
        }
    }

或者如果您可以修改您的列表（任何一个）都可以您可以迭代一个列表，然后检查另一列表中的数据

for (String string : firstList) {
            if(secondList.contains(string)) {
                secondList.remove(string);
            }else {
                secondList.add(string);
            }
        }
        System.out.println(secondList);

这不是一种有效的解决方案，但是它可以满足您的需求，也可能满足您的期望：
