    Default writing a program to choose a sentence and random stuck

    Using java.util.Random to choose a random sentence and print it

    Hi everyone,

    First post here! To preface, I am extremely new to Java and programming in general. The extent of my work with the program is simple JOptionPane's and simple math problems and the use of the Scanner to plug numbers into equations.

    Currently I am trying to write a simple program that selects a String sentence from a list of 4 sentences at random and print it. I am stuck as to how to do this. Here is my syntax so far:


    Java Code:
    import java.util.Random;
     public class Sentences {
         public static void main(String[] args) {
        Random sentences = new Random();
        String sent1 = "This is a test!";
         String sent2 = "This is a test quote!";
         String sent3 = "This is a test quote again!";
         String sent4 = "This is a test quote again again!";
            System.out.println ();

    Dont use 4 single string variables, use a string array, so you can generate with help of the random class a integer from 0 to 3. 0 = array[0] = string1 !

    Keep your sentences in an array (or any other collect. forget about is if you don't know about it). Pick the random number within the valid range (which is through the number of sentences you have) and pick the sentence and display. In that way you know need to stick to four sentences.

    And also please use code tags when you are posting code segments next time. Sometimes unformatted codes are difficult to read.
