打印向量的元素

您可以使用 println 语句直接打印向量的所有元素。

System.out.println(vect);

或者，您可以使用 hasMoreElements() 和 nextElement() 方法逐个打印其元素。

示例

import java.util.*;
public class VectorPrintingElements {
   public static void main(String args[]) {
      
      // initial size is 3, increment is 2
      Vector v = new Vector();

      v.addElement(new Integer(1));
      v.addElement(new Integer(2));
      v.addElement(new Integer(3));
      v.addElement(new Integer(4));
      System.out.println("Capacity after four additions: " + v.capacity());

      // enumerate the elements in the vector.
      Enumeration vEnum = v.elements();
      System.out.println("\nElements in vector:");

      while(vEnum.hasMoreElements())
      System.out.print(vEnum.nextElement() + " ");
      System.out.println();
   }
}

输出

Capacity after four additions: 10

Elements in vector:
1 2 3 4
