以下实例演示了使用 swap() 函数来旋转向量：
Main.java 文件
import java.util.Collections;
import java.util.Vector;
public class Main {
public static void main(String[] args) {
Vector<String> v = new Vector();
v.add("1");
v.add("2");
v.add("3");
v.add("4");
v.add("5");
System.out.println(v);
Collections.swap(v, 0, 4);
System.out.println("旋转后");
System.out.println(v);
}
}
以上代码运行输出结果为：
1 2 3 4 5 旋转后 5 2 3 4 1
