The difference between Java read () and ReadLine ()

1. Read ()

Function: Reads the number of individual characters and returns 1 if it has been read (ranging from 0 to 65535)

Examples are as follows:

                    and nbsp                   Byte[ ] buf = new byte[1024]

< Span class= "hl-types" >                                         Int len

< Span class= "Hl-code" >                    &NBS P                   While (len = in< Span class= "Hl-code". read (buf ) ) > 0) {     //single read count until end return-1

                              &N Bsp                 Out. Write (buf 0len

< Span class= "Hl-identifier" >                            ,         &NB Sp  

< Span class= "hl-brackets" >                                       In.close

                           ,         &NB Sp   Out. Close

 

< Span class= "Hl-code" >< Span class= "Hl-identifier" > 2, readLine ()

Function: Reads a line of text.

Examples are as follows:

String str;

                            &NBS P            while ( (strinreadline ( ) ! = null) {   //If the previous file is empty, the output

                             ,         &NB Sp         System. Out. Println (str)

< Span class= "Hl-identifier" >                             ,         &NB Sp
