Eclipse:代码编码格式UTF-8;控制台编码格式GBK;
对“你好”编码解码
Eclipse:代码编码格式UTF-8;控制台编码格式UTF-8;
对“你好”编码解码
public class EncodeDemo { public static void main(String[] args) throws IOException{ String s = "你好"; byte[] b1 = s.getBytes("utf-8"); System.out.println(Arrays.toString(b1)); String s1 = new String(b1, "iso-8859-1"); System.out.println(s1); } }

编码测试: win7中文操作系统,Eclipse工程编码是UTF-8,Console是UTF-8
从eclipse的console中输入中文“你好”,保存在硬盘中txt格式,用记事本打开结果如下:
结论:
in: 默认编码是UTF-8
out:默认编码是UTF-8
要想记事本打开正常:设置out编码为GBK
注意:但是再读取到Eclipse控制台,正常显示出来,不需要设置编码为GBK。
public static void readIn() throws IOException { BufferedReader br = new BufferedReader(new InputStreamReader(System.in,"UTF-8"));//设置控制台读取编码 BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("c:\\a.txt"),"UTF-8"));//设置写入 txt编码 String s = null; while ((s = br.readLine()) != null) { if (s.equals("over")) { break; } bw.write(s); bw.newLine(); } bw.flush(); br.close(); bw.close(); }
