用流進行byte位元組流的讀寫

import java.io.ByteArrayInputStream;

public class StringByteCount {

	static String str = "This 測試1";

	int countStringByte(String str) {

		int count = 0;
		ByteArrayInputStream sin = new ByteArrayInputStream(str.getBytes());
		int c;
		byte word[] = new byte[2];
		int i = 0;
		try {
			while ((c = sin.read()) != -1) {
				System.out.println("讀到一個位元組:" + c);
				if (c == 0) {
					continue;
				}
				if (c > 0 && c <= 127) {
					count++;
					continue;
				}
				if (c > 127) {
					word[i] = (byte) c;
					if (i == 1) {
						System.out.println("讀到一個漢字:" + new String(word));
						i = 0;
						count++;
					} else
						i++;
				}
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
		return count;
	}

	public static void main(String[] args) {
		StringByteCount sb = new StringByteCount();
		int sum = sb.countStringByte(str);
		System.out.println("總共" + sum + "個字元");
	}
