输入输出流String间的转换

1.String  to  inputStream

InputStream is = new ByteArrayInputStream(string.getBytes());  

　　

2.InputStream to String

　　　　　　

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
int i;  
while ((i = is.read()) != -1) {  
    baos.write(i);  
}  
String str = baos.toString();  
System.out.println(str); 

　3.String写入OutputStream

OutputStream os = System.out;  
os.write(string.getBytes());

　4.OutputStream写入String

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
//向OutPutStream中写入，如 message.writeTo(baos);  
String str = baos.toString();
