Use the file class in Java to bulk create files and bulk modify file names

Batch file creation

1         intCont = 1;2String s = "e:\\ learning material \\Java notes-";3          while(cont<100){4File f =NewFile (s+cont+ ". txt");5             if(!f.exists ()) {6 f.createnewfile ();7             }8cont++;9}

Batch Modify file name

1File File =NewFile ("e:\\ Learning materials");2String SF =File.getabsolutepath ();3File[] F=file.listfiles ();4         intCont =1;5          for(File file2:f) {6String oldname =file2.getname ();7String name = Oldname.replace ("Java note-", "" ");8String newname = sf+ "\ \" +name;9File FF =NewFile (newname);Ten             Booleanb =File2.renameto (FF); One              A             if(b) { -SYSTEM.OUT.PRINTLN ("Modified successfully" +cont+ "files"); -cont++; the             } -}
