Not using an array of strings

Question

how do I write a java method without using an array of strings?
for example:
import java.io.File;
public class rename
public static void main(String[] args)
File src = new File(args[0]);
File dst = new File("c:\\temp\\temp.txt");
boolean wasRenamed = src.renameTo(dst);
I don't want to have main use an array of strings but I want rename to work as a class

Answer 1

This is what I changed it to and am getting an -- Exception in thread "main" java.lang.NoSuchMethodError: main
Sorry this is my first java program
import java.io.File;
class App {
     private App() {
          super();
     static final public void main(final String[] args) {
          switch (args.length) {
               case 1:
                    try {
                         Rename rename = new Rename();
                         rename.rename("c:\\felss\\charles.txt.bak"); // see, it's kind of silly to have same names for class and method
                         System.exit(0);
                    catch (Throwable e) {
                         e.printStackTrace();
                         System.exit(1);
                    break;
               default:
                    System.err.println("Usage: java App [new name]");
                    System.exit(1);
public class Rename {
     public Rename() {
          super();
     final public void rename(final String newName) {
          File src = new File(newName);
          File dst = new File("c:\\felss\\charles.txt");
          boolean done = src.renameTo(dst);
}
