用Java将向量转换为列表的程序
假设以下是带有值的向量-
Vector<String> v = new Vector<String>();
v.add("20");
v.add("40");
v.add("60");
v.add("80");
v.add("100");现在，将上面的Vector转换为List-
List<String>myList = new ArrayList<String>(v);
示例
以下是在Java中将Vector转换为List的程序-
import java.util.*;
public class Demo {
public static void main(String[] args) {
Vector<String> v = new Vector<String>();
v.add("20");
v.add("40");
v.add("60");
v.add("80");
v.add("100");
v.add("120");
v.add("140");
v.add("160");
v.add("200");
System.out.println("Vector elements = " + v);
List<String>myList = new ArrayList<String>(v);
System.out.println("List (Vector to List) = " + myList);
}
}输出结果
Vector elements = [20, 40, 60, 80, 100, 120, 140, 160, 200] List (Vector to List) = [20, 40, 60, 80, 100, 120, 140, 160, 200]
示例
让我们看另一个例子-
import java.util.*;
public class Demo {
public static void main(String[] args) {
Vector<String> v = new Vector<String>();
v.add("20");
v.add("40");
v.add("60");
v.add("80");
v.add("100");
v.add("120");
v.add("140");
v.add("160");
v.add("200");
System.out.println("Vector elements = " + v);
List<String>myList = Collections.list(v.elements());
System.out.println("List (Vector to List) = " + myList);
}
}输出结果
Vector elements = [20, 40, 60, 80, 100, 120, 140, 160, 200] List (Vector to List) = [20, 40, 60, 80, 100, 120, 140, 160, 200]
