Eclipse控制台不打印中文字符

我编写了一个Java函数,它接受一个字符串参数,并使用一些逻辑从中生成一个随机id。如果我的字符串包含英文字符,那么一切正常,但是当我传递中文字符时,它们被???

取代

这是我的代码:

public static String generateId(String inputString) {
        /**
         * Split input string on the basis of white spaces
         */
        String arr[] = inputString.split(" ");
        /**
         * Change the first character of first substring to lowercase
         */
        String id = arr[0].substring(0, 1).toLowerCase() + arr[0].substring(1);
        if(arr.length > 1)
        {
        for (int i = 1; i < arr.length; i++) {
            /**
             * Change the first character of remaining substrings to uppercase
             * and append to id
             */
            if(arr[i].trim().length() != 0)
            {
                id = id + arr[i].substring(0, 1).toUpperCase() + arr[i].substring(1);
            }
        }
        }
        int length = id.length();
        Random random = new Random();
        /**
         * If the length of id is less than 8 then append random digits to make
         * length equals to 8 else take a substring of length equals to 8
         */
        if (length < 8) {
            int len = 8 - length;
            StringBuilder sb = new StringBuilder(len);
            for (int i = 0; i < len; i++) {
                sb.append((char) ('0' + random.nextInt(10)));
            }
            id = id + sb;

        } else {
            id = id.substring(0, 8);
        }
        /**
         * Append 4 digits random number to make length of id equals to 12
         * characters long
         */
        return id + String.format("%04d", random.nextInt(10000));
    }

以下是我对不同案例的输出:

 System.out.println(MyClass.generateId("anyid"));

输出:anyid0660920

System.out.println(MyClass.generateId("这是标题"));

输出:???? 14102367

我该如何处理这个问题?

将控制台编码更改为UTF-8

转到Run -> Run Configurations -> Common Tab -> Console Encoding (or just Encoding, in newer versions) -> Choose UTF - 8

默认情况下,它是拉丁语编码(8859),不支持中文。
