How do we input a bin file in java?

 

to read or write binary files in java you can use BufferedInputStream and BufferedOutputStream functions.Though you will also need to FileInputStream and FileOutputStream functions.

A basic example is below

to read the file:-

 FileInputStream fi = new FileInputStream(new File("(File name here)"));
    BufferedInputStream reader = new BufferedInputStream(fi);
    int ch;
    while ((ch = reader.read()) != -1) {
        System.out.print((char) ch);

reader.close

to write the file

FileOutputStream fo = new FileOutputStream(new File("(File name here)"));
    BufferedOutputStream writer = new BufferedOutputStream(fo);
    writer.write("Hey!".getBytes());
    writer.write("\n".getBytes());
    writer.write("How are you?".getBytes());
    writer.flush();
    writer.close();

In ove cases you need to put your File name of the file you want to read or write instead of(File name here)
