File copying through character stream

Only text files can be copied using character streams

/ * * copy files through character stream * * @ param sourcePath source file path * @ param targetPath destination file path * / public static void copyFileByReaderAndWriter (String sourcePath, String targetPath) {/ / source file path File source = new File (sourcePath); / / destination file path File target = new File (targetPath) / / cannot copy if (! source.exists ()) {return;} / / if the source file does not exist, create if (! target.getParentFile (). Exists ()) {target.getParentFile (). Mkdirs ();} FileReader in = null; FileWriter out = null if the destination file directory does not exist Try {/ / character input stream and character output stream in = new FileReader (source); out = new FileWriter (target); char [] c = new char [1024]; int temp = 0; / / read 1024 characters while ((temp = in.read (c))! =-1) {/ / output to file out.write (c, 0, temp) }} catch (IOException e) {e.printStackTrace ();} finally {/ / close stream try {if (in! = null) {in.close ();} if (out! = null) {out.close ();}} catch (IOException e) {e.printStackTrace () } this is the end of the article on "how java can copy files through character stream".
