对于给定的两个ArrayList,我们可以使用filter方法来筛选出满足特定条件的元素。 下面是一个示例代码: 代码语言:java 复制 importjava.util.ArrayList;importjava.util.List;publicclassMain{publicstaticvoidmain(String[]args){List<Integer>list1=newArrayList<>();list1.add(1);list1.add(2);list1.add(3);li...

The following Java program swaps two specified elements in a given list. In this example, we are swapping the elements at positions ‘1’ and ‘2’. The elements are these positions in the list are ‘b’ and ‘c’. Please note that indexes start from0. ArrayList<String>list=newArrayList<...
The JavaSetsallow only unique elements. When we push both lists in aSetand theSetwill represent a list of all unique elements combined. In our example, we are usingLinkedHashSetbecause it will preserve the element’sorder as well. ArrayList<String>listOne=newArrayList<>(Arrays.asList("a","...
