[jira] Created: (HARMONY-4357) [classlib][luni] Compatibility:
CharArrayReader.reset() behavior differs on Harmony and RI if the stream
hasn't been marked
[classlib][luni] Compatibility: CharArrayReader.reset() behavior differs on Harmony and RI if the stream hasn't been marked
---------------------------------------------------------------------------------------------------------------------------
Key: HARMONY-4357
URL: https://issues.apache.org/jira/browse/HARMONY-4357
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Elena Sayapina
Priority: Minor
CharArrayReader.reset() behavior differs on Harmony and RI if the stream hasn't been marked
If the stream was constructed to begin reading at a nonzero offset, Harmony reset the stream to the very beginning while RI reset it to the initial offset.
Please, consider the following code:
import java.io.CharArrayReader;
import java.io.IOException;
public class CharReaderTest {
static String str = "offsetHello world!";
static char[] data = new char[str.length()];
static int offsetLength = 6;
static int length = data.length - offsetLength;
public static void main(String[] args) throws IOException {
for(int i=0; i<str.length(); i++) data[i] = str.charAt(i);
CharArrayReader reader = new CharArrayReader(data, offsetLength, length);
System.out.print("Before reset(): ");
for (int i = 0; i < length; i++) System.out.print((char) reader.read());
reader.reset();
System.out.print("\nAfter reset(): ");
for (int i = 0; i < length; i++) System.out.print((char) reader.read());
}
}
