How can I print 1 random string from 4?

Question

String haiku1 = "As the wind does blow\nAcross the trees, I see the\nBuds blooming in May."; 
String haiku2 = "I walk across sand\nAnd find myself blistering\nIn the hot, hot heat."; 
String haiku3 = "Falling to the ground,\nI watch a leaf settle down\nIn a bed of brown.";  
String haiku4 = "It’s cold and I wait\nFor someone to shelter me\nAnd take me from here.";

I need to print a random string out of the four listed above. How could I do this? I know I must use random. Thanks for any help

It's better to put your strings in an array.

String haiku[] = new String[4];
haiku[0] = "/*your string*/";
haiku[1] = "/*your string*/";
haiku[2] = "/*your string*/";
haiku[3] = "/*your string*/";

Then generate random number from 0-3 to access the index of your array.

Random randomizer = new Random();         //import java.util.Random;
int index = randomizer.nextInt(4);
System.out.println("Generated random string: " + haiku[index]);

Like this -

    ...
    int nextInt = new Random().nextInt(4);
    switch (nextInt) {
    case 1:
        System.out.println(haiku1);
        break;
    case 2:
        System.out.println(haiku2);
        break;
    case 3:
        System.out.println(haiku3);
        break;
    case 4:
        System.out.println(haiku4);
        break;

    }

Create an array of your above Strings and use java.util.Random class to generate random number for array index.

Is there a way to do this without using arrays? – user1755022 Jan 10 '13 at 07:35

Generate a random number and then access value stored at particular position in array:

  Random r = new Random();
  int index = r.nextInt(4);

I would do it this way:

String[] myArray = {haiku1,haiku2,haiku3,haiku4};
Random rand = new Random();
int randomnum = rand.nextint(4);
System.out.println(myArray[randomnum]);

    String[] array={haiku1,haiku2,haiku3,haiku4};

    Random rndm=new Random();

    System.out.println( "Generated Random String: "+array[rndm.nextInt((array.length-1) - 0 + 1) + 0]);

How can I print 1 random string from 4?
