为了反转LinkedList元素的顺序，我们可以使用class的reverse(List<?> list)静态方法java.util.Collections。这是示例：
package org.nhooo.example.util;
import java.util.LinkedList;
import java.util.Collections;
public class LinkedListReverseOrder {
public static void main(String[] args) {
LinkedList<String> grades = new LinkedList<>();
grades.add("A");
grades.add("B");
grades.add("C");
grades.add("D");
grades.add("E");
grades.add("F");
System.out.println("Output in original order:");
System.out.println("=========================");
for (String grade : grades) {
System.out.println("Grade = " + grade);
}
// 颠倒链表对象中的元素顺序。
Collections.reverse(grades);
System.out.println("Output in reverse order:");
System.out.println("=========================");
for (String grade : grades) {
System.out.println("Grade = " + grade);
}
}
}这是程序的输出：
Output in original order: ========================= Grade = A Grade = B Grade = C Grade = D Grade = E Grade = F Output in reverse order: ========================= Grade = F Grade = E Grade = D Grade = C Grade = B Grade = A
