Week 6 Practice Problems
[Topic: Arrays]

---

• Problem 1: Create a method that takes in a string array. Then print out all words that are of length 6 or more.

String[] words = {
	"apple", "banana", "cherry", "dog", "elephant", "fish",
	"grape", "hat", "igloo", "jacket", "kangaroo",
	"lemon", "monkey", "noodle", "orange", "penguin",
	"quilt", "rabbit", "snake", "tiger", "umbrella",
	"vanilla", "watermelon", "xylophone", "yogurt", "zebra",
	"sun", "moon", "star", "flower", "ocean", "mountain",
	"river", "cloud", "rain", "snow", "fire", "earth",
	"wind", "volcano", "island", "desert", "forest",
	"castle", "dragon", "knight", "princess", "wizard",
	"unicorn"
};

public static void words6Plus(String[] words) {
	for (int i = 0; i < words.length; i++) {
        if (words[i].length() >= 6) {
            System.out.println(words[i]);
        }
    }
}

• Problem 2: Create a method that takes in a 2D string array. Then print out all words that are of length 6 or more.

String[][] words2D = {
    {"apple", "banana", "cherry"},
    {"dog"},
    {"elephant", "fish", "grape", "hat"},
    {"igloo", "jacket", "kangaroo"},
    {"lemon", "monkey"},
    {"noodle"},
    {"orange", "penguin", "quilt", "rabbit", "snake"},
    {"tiger", "umbrella", "vanilla", "watermelon", "xylophone"},
    {"yogurt", "zebra"},
    {"sun", "moon", "star", "flower"},
    {"ocean"},
    {"mountain", "river", "cloud", "rain"},
    {"snow"},
    {"fire", "earth", "wind", "volcano", "island"},
    {"desert", "forest", "castle", "dragon", "knight"},
    {"princess", "wizard"},
    {"unicorn"}
};

public static void words6Plus2D(String[][] words) {
	for (int i = 0; i < words.length; i++) {
		for (int j = 0; j < words[i].length; j++) {
	        if (words[i][j].length() >= 6) {
	            System.out.println(words[i][j]);
	        }
	    }
    }
}
