changing from frequencies to percentages

Here i have a piece of code that reads in a text file, however it only outputs how many letters there are in the word(s). I want it to output the percentage of words instead. Could anyone help me figure this out? Would highly appreciate it!

public static void fileanalysis(){
                  Scanner scan;
                    try {
                        scan = new Scanner(new File("G:/test.txt")); //change directory to load in text file
                            } 
                        catch (Exception e) {
                            System.out.println("File was not found ");
                                return;
                  }
                        while(scan.hasNextLine()) {
                            String text2 = scan.nextLine();
                                System.out.println ("\n--------------------------------------------------------------------------------------------------------");
                                System.out.println ("                            Words loaded in from the file: " + text2);
                                System.out.println ("--------------------------------------------------------------------------------------------------------");
                                System.out.print("\n");
                                System.out.print("");
                                char uinput;

                                for(int i = 97; i<123 ; i++){
                                    uinput = (char)i;
                                    System.out.print("   " + uinput );
                                    }                       
                                    System.out.println ("\n--------------------------------------------------------------------------------------------------------");
                                    for(int i = 97; i<123 ; i++)
                                {
                                uinput = (char)i;
                                    System.out.format("   "+frequencies(text2,uinput));
                                }
                                System.out.print("\n\n");
                              main(null);
                        }
            }
                            public static int frequencies(String input, char uinput){
                                int count = 0;
                              for (int i = 0; i < 26; i++)
                                {
                                    if (input.charAt(i) == uinput)
                                    {
                                         count++;
                                    }
                                }
                                return count;
                            }
