I need to write different methods for printing phrases with loops and I'm having trouble with printing an array. My assignment is to have each method print the phrase 5 times but I can't figure out how to do it with the array. This is what I have so far and it only prints once. 

  String[] words = {"I'm ","Ready ","Now!"};
  for(int i=0; i < 5; i++)
  {
  System.out.print(words[i]);
  }

  • One loop to count from 1 to 5, another inner one to count from 0 to the last element of the array. – Federico klez Culloca Nov 08 '18 at 16:56
  • You could use nested loops, the outer for loop to tell it to run 5 times, and the inner one which is the loop you already created inside. That would do it 5 times. But you would want to change your current loops `I < 5` to `I < arraylength - 1`. – arahman Nov 08 '18 at 16:56

    I'm pretty sure this will throw an `ArrayOutOfBoundsException` – Nicholas K Nov 08 '18 at 16:56

    Another approach is to create a String by [joining the array elements](https://stackoverflow.com/questions/1515437/java-function-for-arrays-like-phps-join), then use a for loop to print the String 5 times. – Andrew S Nov 08 '18 at 17:01

below code will print the phrase 5 times.

String[] words = {"I'm ","Ready ","Now!"};
  for(int i=0; i < 5; i++)
  {
   for (String word: words) 
    {
     System.out.print(word);
    }
    System.out.println("");
  }

I wouldn't use nested loops. I'd first concatenate the words to form the phrase, then I would write the phrase five times, like this:

String[] words = { "I'm ", "Ready ", "Now!" };
String phrase = String.join("", words);

for (int i = 0; i < 5; i++) {
    System.out.println(phrase);
}

Prints:

I'm Ready Now!
I'm Ready Now!
I'm Ready Now!
I'm Ready Now!
I'm Ready Now!

I'm not sure whether the formatting is important but if not, you could use the Arrays.toString() method:

String[] words = {"I'm ","Ready ","Now!"};
for(int i=0; i < 5; i++)
{
  System.out.println(Arrays.toString(words));
}

You can create a method. For instance it can be implemented like that. 

public void printWords(String[] wordsArray, int repeatPhraseNumber) {
    for(int i=0;i<wordsArray.length;i++) {
       for(int repeatCount=0;repeatCount<repeatPhraseNumber;repeatCount++) {
           System.out.println(wordsArray[i]);
       }
    }
}

And you can call this like that, wordConsolePrinter is an instance of a class that has the printWords method. You can call it as follows.

String[] words = {"Hello","World"};
wordConsolePrinter.printWords(words,5);

And this will produce the following output.

Hello
Hello
Hello
Hello
Hello
World
World
World
World
World

If you need to print all words as a single sentence/phrase, the method should be modified as follows.

public void printWords(String[] wordsArray, int repeatPhraseNumber) {
    for(int repeatCount=0;repeatCount<repeatPhraseNumber;repeatCount++) {
       for(int i=0;i<wordsArray.length;i++) {
           System.out.print(wordsArray[i]);
           System.out.print(" "); // Space between words
       }
       System.out.println(""); // New line
    }
}

And this will output

Hello World
Hello World
Hello World
Hello World
Hello World

Of course this could be implemented without using methods.

This is a really easy task, please try to read more about loops and arrays.
