Examples of java.io.InputStream.skip()

java.io.InputStream.skip()
Skips n number of bytes in this InputStream. Subsequent read()'s will not return these bytes unless reset() is used. This method may perform multiple reads to read n bytes. This default implementation reads n bytes into a temporary buffer. Concrete subclasses should provide their own implementation. @param n the number of bytes to skip. @return the number of bytes actually skipped. @throws IOException If the stream is already closed or another IOException occurs.

    @Test
    public void testSkip() throws IOException {
        byte[] src = "HELLO MINA!".getBytes();
        ByteBuffer bb = ByteBuffer.wrap(src);
        InputStream is = new ByteBufferInputStream(bb);
        is.skip(6);


        assertEquals(5, is.available());
        assertEquals('M', is.read());
        assertEquals('I', is.read());
        assertEquals('N', is.read());
