Java Reading from a File using FileChannel -

i've been getting strange outputs code upon reading large file, file printed using while loop 99,999 digits however, upon reading file , printing contents outputs 99,988 lines. also, using bytebuffer option reading file? i've seen other code using charbuffer, i'm not sure 1 should use, , in cases should use them. note: filepath path object pointing file on disk.

    private void bytechanneltrial() throws exception {         try (filechannel channel = (filechannel) files.newbytechannel(filepath, read)) {             bytebuffer buffer = bytebuffer.allocate(1024);             string encoding = system.getproperty("file.encoding");             while (channel.read(buffer) != -1) {                 buffer.rewind();                 system.out.print(charset.forname(encoding).decode(buffer));                 buffer.clear();             }         } 

usually, flip() called before buffer data read. rewind() method bellowing works:

public final buffer rewind() {     position = 0;     mark = -1;     return this; } 

it not set 'limit' flip() does:

public final buffer flip() {     limit = position;     position = 0;     mark = -1;     return this; } 

so, take tray using flip() instead of rewind() before reading.
