java - 我的交错链接列表功能没有更改所需的列表

Question

我试图交错两个列表，这样：

list1 以 {a1,a2,a3,a4,a5} 开头 list2 以 {b1,b2,b3,b4,b5} 开头

我希望他们成为 {a1,b2,a3,b4,a5} {b1,a2,b3,a4,b5}

这是我的代码：

public void interleave(A3LinkedList other) {
  A3Node thisCurrent = this.head;
  A3Node otherCurrent = other.head;
    int count = 1;
    while(count <= this.length){
        System.out.println("List1 current at loop "+ count + ": " + thisCurrent); // just to debug
        System.out.println("List2 current at loop "+ count + ": " + otherCurrent);

        A3Node tempThis = thisCurrent;
        A3Node tempOther = otherCurrent;

        //if(count%2 == 0){ //if count is even, aka every second object in list
            thisCurrent = tempOther; // makes thisCurrent same as otherCurrent
            otherCurrent = tempThis; // makes otherCurrent same as temp saved
        //}


        thisCurrent = thisCurrent.next;
        otherCurrent = otherCurrent.next;
        count ++;
    }
}

while 循环中 println 方法的输出显示节点交换正确，但另一个测试程序的最终结果显示列表根本没有改变。

while循环内部的输出：

List1 current at loop 1: A
List2 current at loop 1: L
List1 current at loop 2: M
List2 current at loop 2: B
List1 current at loop 3: C
List2 current at loop 3: N
List1 current at loop 4: O
List2 current at loop 4: D
List1 current at loop 5: E
List2 current at loop 5: P
List1 current at loop 6: Q
List2 current at loop 6: F
List1 current at loop 7: G
List2 current at loop 7: R

测试器的输出：{ABCDEFG} {LMNOPQR} 测试失败：第 203 行的 testInterleave 失败的测试：第 204 行的 testInterleave

可以看到，测试器的输出不是它应该的，它没有通过测试。为什么？
