As we know java String is char array. When we look through code source
for
StringBufferInputStream and StringReader read method we can see
difference
between:

StringBufferInputStream:
public synchronized int read() {
    return (pos < count) ? (buffer.charAt(pos++) & 0xFF) : -1;

StringReader:
public int read() throws IOException {
    synchronized (lock) {
        ensureOpen();
        if (next >= length)
        return -1;
        return str.charAt(next++);
    }
    }

As we see StringBufferInputStream's read method return only low byte
from char as int . That is why it is deprecated.

I need to generate an InputStream from a String containing some test

StringBufferInputStream is deprecated, and the documentation points to
StringReader.

However, after looking through java.io several times, I have not found
how to construct an InputStream from a Reader.

What is the proper, undeprecated, replacement code for:

> InputStream in = new StringBufferInputStream(someString);

InputStream in = new ByteArrayInputStream(someString.getBytes(encodin=

g));

must be a candidate.

Thanks.

That works, and gets rid of the warnings. But why does the
StringBufferInputStream documentation say "As of JDK 1.1, the preferred
way to create a stream from a string is via the StringReader class." if
StringReader cannot do StringBufferInputReader's job?
