Examples of java.io.RandomAccessFile.readChar()

java.io.RandomAccessFile.readChar()
Reads a 16-bit character value from this stream. @return char the next char value from the source stream. @throws IOException If a problem occurs reading from this DataInputStream. @see DataOutput#writeChar(int)

        raf.writeChars("HelloWorld");
        char[] hchars = new char[10];
        "HelloWorld".getChars(0, 10, hchars, 0);
        raf.seek(0);
        for (int i = 0; i < hchars.length; i++)
            assertEquals("Incorrect string written", hchars[i], raf.readChar());
        raf.close();
    }
