Java数组转换集合
如何将一个数组转换成一个集合?
解决方法
下面的例子演示了一个数组转换成一个集合,使用Java Util类的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(); } Listlist = Arrays.asList(name); System.out.println(); for(String li: list){ String str = li; System.out.print(str + " "); } } }
结果
上面的代码示例将产生以下结果。
How many elements you want to add to the array: red white green red white green
