java - 字符串数组到字符串

Question

我正在尝试获取任意长度的 String[] 并将其打印为字符串，最好带有字段分隔符。现在我有:

String[] start = {"first", "second", "third"}; //[] to convert
String cC = "";
String finish = ""; // Final String
String cC1 = "";
{
    for (int i = 0; i < puts.length; i++) {
        cC = puts[i] + ", ";
        cC1 = (finish + cC);
        finish = cC1;
    }
}

但由于某种原因它只返回“第二个”值。如何才能正确连接这些值？

另外，我可以使用 finish += cC 来简化代码吗？ ？谢谢。

Answer 1

String[] start = {"first", "second", "third"};
String addedTogether = Arrays.toString(start);

System.out.println(addedTogether);
//prints [first, second, third]
