+ 1 First you should ensure that both arrays are of the same length. Second you don't need a second loop for this task. You can just iterate over both with the same index i and compare the values at exactly this point. If you're comparing each element at index one in first array ...
CompareTwoListsListArrays 总结 通过Java8中的Stream API,我们可以轻松地对比两个List是否相等。使用equals方法可以快速比较两个List的内容和顺序是否一致,从而判断它们是否相等。希望本文能帮助您更好地理解Java8中对比两个List是否相等的方法,并且能够在实际开发中应用到这个知识点中。
java.util.Arrays.sort(stu);for(Student s:stu) { System.out.println(s); } } } 结果 但是在设计类的时候,往往没有考虑到让类实现Comparable接口,那么我们就需要用到另外的一个比较器接口Comparator。 从上面的实例我们可以发现,compareTo(T o)只有一个参数,而Comparator接口中必须要实现的compare(T o1,T...
