Generating random words in Java?

Question

I wrote up a program that can sort words and determine any anagrams. I want to generate an array of random strings so that I can test my method\'s runtime.

Answer 1

You can call this method for each word you want to generate. Note that the probability of generating anagrams should be relatively low though.

String generateRandomWord(int wordLength) {
    Random r = new Random(); // Intialize a Random Number Generator with SysTime as the seed
    StringBuilder sb = new StringBuilder(wordLength);
    for(int i = 0; i < wordLength; i++) { // For each letter in the word
        char tmp = 'a' + r.nextInt('z' - 'a'); // Generate a letter between a and z
        sb.append(tmp); // Add it to the String
    }
    return sb.toString();
}
