我怎么能转换字符串数组转换成Java中的 INT 数组？我从控制台读取整数字符流成字符串阵列，以

How can I convert a String array into an int array in java? I am reading a stream of integer characters into a String array from the console, with

BufferedReader br = new BufferedReader (new InputStreamReader(System.in)); for(c=0;c<str.length;c++) str[c] = br.readLine();

其中，海峡[] 为String类型。我想比较海峡[] 不能对字符（错误）进行内容...因此我想从控制台读取 INT 。这可能吗？

where str[] is String typed. I want to compare the str[] contents ... which can't be performed on chars (the error) And hence I want to read int from the console. Is this possible?

推荐答案

的Integer.parseInt（字符串）; 是你想要的东西。

Integer.parseInt(String); is something that you want.

试试这个：

int[] array = new int[size]; try { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); for (int j = 0; j < array.length ; j++) { int k = Integer.parseInt(br.readLine()); array[j] = k; } } catch (Exception e) { e.printStackTrace(); }

不管怎么说，你为什么不使用扫描仪？如果您使用扫描仪这将会是你要容易得多。 ：）

Anyways,why don't you use Scanner? It'd be much easier for you if you use Scanner. :)

int[] array = new int[size]; try { Scanner in = new Scanner(System.in); //Import java.util.Scanner for it for (int j = 0; j < array.length ; j++) { int k = in.nextInt(); array[j] = k; } } catch (Exception e) { e.printStackTrace(); }
