  问题描述

  如何将数组转换为集合？
• 

  解决方案

  以下示例演示了将数组转换为 Java Util 类的集合 Arrays.asList(name) 方法。

  
  import java.util.*;
  import java.io.*;
  public class ArrayToCollection{
     public static void main(String args[]) throws IOException {
        BufferedReader in = new BufferedReader (new InputStreamReader(System.in));
        System.out.println("How many elements you want to add to the array: ");
        int n = Integer.parseInt(in.readLine());
        String[] name = new String[n];
        
        for(int i = 0; i < n; i++) {
           name[i] = in.readLine();
        }
        List<String> list = Arrays.asList(name); 
        System.out.println();
        
        for(String li: list) {
           String str = li;
           System.out.print(str + " ");
        }
     }
  }
