If you are running the program from command line, maybe you wan to put the FormatString.java in your bin folder.

With Eclipse

ProjectRootFolder
               bin
                  FromatString.java
                  ReplacingText.class

               src
                  ReplacingText.java

With Netbeans

ProjectRootFolder
               build
                   classes
                        FromatString.txt

                        replacinttext
                                ReplacingText.class

               src
                  ReplacingText.java

C:\Users\Dhaval\Desktop\Java Assignment\ReplacingText\build\classes>java replacingtext.ReplaceText FormatString.java public private
