Java Collection - 如何替换列表中的元素

The object being replaced is returned by the set() method.


    
import java.util.Arrays;
import java.util.List;
public class MainClass {
  public static void main(String[] a) {
    List list = Arrays.asList(new String[] { "A", "B", "C", "D" });
    list.set(2, "X");
    System.out.println(list);
  }
}
