Random list, SecretPhrase Java Project -

my school project requires me modify last assignment (code below) pull random phrase list of @ least 10 user guess. drawing blank on this. appreciated. understand have add class import text file or list, need modify loop in order randomly select?

    import java.util.scanner; // allows user read different value types      public class secretphrase {      string phrase; //     scanner scan = new scanner(system.in);      secretphrase(string phrase){         this.phrase = phrase.tolowercase();     }      public static void main(string args[]){         secretphrase start = new secretphrase("java great"); // phrase user have identify         start.go(); // starts program      }      void go(){         string guess;         string word="";         string[] words = new string[phrase.length()]; // array store charachters         arraylist<string> lettersguessed = new arraylist();            for(int i=0;i<phrase.length();i++){              if(phrase.charat(i)== ' '){words[i] = " ";}              else{words[i] = "*";} // array uses * hide actual letters         }          int gcount =0; // records count              while(!word.equals(phrase)){ // continues loop             word = "";             int lcount = 0;             system.out.print("guess letter> ");             guess = scan.next();               for(int i=0;i<phrase.length();i++){ // accounts attempts user use more 1 charachter @ time.                 if((guess.charat(0)+"").equals(phrase.charat(i)+"")&&(lettersguessed.indexof(guess.charat(0)+"")==-1)){                      words[i] = ( guess.charat(0))+ "";                      lcount++;                  }             }             lettersguessed.add(guess.charat(0)+""); // reveals letter in phrase             system.out.println("you found " + lcount +" letters"); // prints out total number of times charachter in phrase              for(int i=0;i<words.length;i++){                 word=word+words[i];              }             system.out.println(word);             gcount ++;         }         system.out.println("good job! took " + gcount + " guesses!" ); // prints out result total count      } } 

in existing code, creating secretphrase object phrase guess:

public static void main(string args[]){     secretphrase start = new secretphrase("java great");     start.go(); // starts program  } 

you should replace list (either arraylist or linkedlist fine) , populate data (given either file, user input or hard-coded):

arraylist<secretphrase> phrases = new arraylist<secretphrase>(); //reading file: file file = new file("myphrases.txt"); filereader reader = new filereader(file); bufferedreader br = new bufferedreader(reader); string phrase = null; while ((phrase = br.readline()) != null) {     phrases.add(new secretphrase(phrase)); } 

now either use random on phrases.size() , execute go on it, or if you're looking series of phrases, can create permutation , loop on them. i'm not sure requirements here are.
