java - 如何从 JAVA 中的两个集合中获取不匹配的字符串？

转载作者：行者123 更新时间：2023-11-29 06:33:55

我应该如何只获取一次不匹配的元素？我的代码如下:

Set<String> hashSet = new HashSet<String>(); //consist 90 elements
Set<Object> hashSet2 = new HashSet<Object>();// consist 9 elements
for (String string : hashSet ) {
                for(Object obj: hashSet2){
                     if(obj.equals(string)){
                         System.out.println(string + "\t is present in tracking     sheet");     
                     }
                     if(!obj.equals(string)){
                          System.out.println(string + "\t is not sheet");

                     }
                    }

         }

首先使用 if() 我能够获得两个集合中的元素。使用第二个 if() 我得到了第一组中所有元素的结果。

    GBS-41315    is not in sheet

感谢大家提供意见和解决方案。我选择了一个作为可接受的答案(KISS:保持简短)(如果允许的话会选择更多 :-))，但很多都是有帮助的。

最佳答案

就这样吧:

Set<String> hashSet = new HashSet<String>(); // consist 90 elements
Set<Object> hashSet2 = new HashSet<Object>(); // consist 9 elements
for (String string : hashSet) {
    if (hashSet2.contains(string)) {
        System.out.println(string + "\t is present in tracking     sheet");
    } else {
        System.out.println(string + "\t is not sheet");
    }
}
