1.String to InputStream

public static InputStream String2InputStream(String name) {    return new ByteArrayInputStream(name.getBytes());  }

 

 

2.InputStream to String

    这里提供几个方法。

1   public static String InputStream2String(InputStream input,String encode) throws IOException { 2     StringBuilder builder = new StringBuilder(); 3  4     InputStreamReader reader = new InputStreamReader(input,encode); 5     BufferedReader bufferedReader = new BufferedReader(reader); 6     String line = null; 7     try { 8       while ((line = bufferedReader.readLine()) != null) { 9         builder.append(line);10       }11     } catch (IOException e) {12       e.printStackTrace();13     } finally {14       input.close();15     }16     return builder.toString();17   }18 19   public static String InputStream2String2(InputStream input) throws IOException {20     StringBuffer buffer = new StringBuffer();21     byte[] b = new byte[1024];22     int n;23     try {24       while ((n = input.read(b)) != -1) {25         buffer.append(new String(b, 0, n));26       }27     } catch (IOException e) {28       e.printStackTrace();29     } finally {30       input.close();31     }32     return buffer.toString();33   }34 35   public static String InputStream2String3(InputStream input) throws IOException {36     ByteArrayOutputStream outputStream = new ByteArrayOutputStream();37     int i;38     try {39       while ((i = input.read()) != -1) {40         outputStream.write(i);41       }42     } catch (IOException e) {43       e.printStackTrace();44     } finally {45       input.close();46     }47     return outputStream.toString();48   }
