public class ArraySkills { public static void main(String[] args) { // *********************** // For each item below you must code the solution using a plain // Java array. You may not use any of the methods found in the // Arrays class or the Collections classes. Manually perform // all operations without relying on system libraries to do the work. // // *********************** // Use this array for all operations String[] myData; // 1. Instantiate the given array to hold 10 Strings. // 2. Add your name to the Array at index 0 and a friend’s name to the // Array at index 4 // 3. Move your friend’s name to index 0 (overwriting your name) in the // array and “delete” their name from index 4 // 4. Fill up all of the remaining indeces in the array with more names // 5. Swap the values at index 5 and index 1. Put the value at index 5 // in index 1 and the value at index 1 in index 5. // 6. Print the array from beginning to end. // 7. Shuffle the array of strings. In other words, randomize the // contents of the array like you might a deck of cards. It’s OK // to use a Random object or the Math.random() method here. // 8. Find and print the longest and shortest Strings in the array. // It’s fine to use Math class methods here. // 9. Add up the total number of characters in all of the strings in // the array and print the answer // 10. Prompt the user for a String and then perform a linear search // of the array to see if that string is or is not in the array. // Print if it is or is not found. // 11. Remove the item at index 4 of the array by shifting everything // after it one spot over. This is similar to how everybody waiting // in a line steps up one step if somebody in front of them leaves // the line. This means your array should have one empty index at // the end after the shift (delete the duplicate item at the end). // 12. Create a new array that is twice as big as the current array and // copy all of the items from the old array to the new array. When // complete, assign the new bigger array to the myData variable so // the old array gets garbage collected.. // 13. Prompt the user to enter 2 numbers within the range of the array’s // length. If the first is larger than the second print backwards // from that index to the first. If the second is larger than the // first, print forward in the array from the first index to the second. }
