These source code samples are taken from different open source projects. If you really want to print the contents of the file, write the bytes directly: int b; while ( (b = fis.read ()) >= 0) { System.out.write (b); } If you're using Java 9 or later, you can just use: fis.transferTo (System.out); However, neither option will show the contents of a Word document in a readable form. public class MultipartStream extends Object Low level API for processing file uploads. algorithm 102 Questions android 1063 Questions android-studio 176 Questions arraylist 111 Questions arrays 274 Questions eclipse 167 Questions firebase 103 Questions gradle 146 Questions hibernate 254 Questions intellij-idea 148 Questions java 8488 Questions java-8 163 Questions java-stream 145 Questions javafx 117 Questions jpa 166 Questions json 198 Questions junit 120 Questions kotlin 179 .
