How to rename jar file name to new name or modify the existing jar file name ?

Put the jar file in particular location in your machine and provide that path in your code as I have provided as D://apache-tomcat-8.0.39//webapps//examples//test

Code:

import java.io.File;

public class Test {

       public static void main(String[] args) {

              File dir = new File("D://apache-tomcat-8.0.39//webapps//examples//test");

              File[] filesList = dir.listFiles();

              int i=1;

             

              for (File file : filesList) {

                     if (file.isFile()) {

                           File oldfile =new File("D://apache-tomcat-8.0.39//webapps//examples//test//"+file.getName());

                           File newfile =new File("D://apache-tomcat-8.0.39//webapps//examples//test//"+file.getName().replaceAll("__V1.0.jar", ".jar"));

                           oldfile.renameTo(newfile);

                           System.out.println(file.getName().replaceAll("__V1.0.jar", ".jar"));

                                 

                     }

              }

        }

}
