Write a program that creates an array of four float elements. Use a for loop to read and store a float value at each index in the array. Then use a for-each loop to print out each element to the console. Solution The solution is partially provided below. Fill in the blanks to complete the missing parts. float[] values - ; // initialize array of 4 elements Scanner scanner = new Scanner(System. in); for (int i = 0; ; i++) { System. out. print("Enter" + (i + 1) + ": "); = scanner. nextFloat(); } for ) { System. out. print(val + " "); } System. out. println();

Ihave a music player on my phone. i can buy songs, add them to playlists and play them. obviously it would be redundant to store each song in each playlist; each playlist is just a list of pointers to the songs. for this lab you will simulate this behavior. your program will need to have options to: add songs to the system library (you will store the text of the first line of the song, rather than the audio) add playlists add songs to a playlist list playlists play a playlist list all of the songs in the library with a count of how many times each song has been played remove a song from a playlist remove a playlist remove a song from the library (and thus from all playlists that contain it) note that we will not be checking many error cases. in real programming this would be bad, you should usually try to recognize and respond to as many types of errors as you can. in the context of class we are trying to acquaint you with as many concepts as possible, so for the sake of educational efficiency we will not be checking most errors in this lab, you may assume that your user provides correct input. you may add all appropriate error testing if you wish, but we will not be testing for it.

22. sata3 allows for data transfer rates of 600 mb/s. explain why you would likely not be able to copy data from one hard drive to another at anywhere close to this speed. also, what could be upgraded on the computer to achieve transfer speeds closer to 600 mb/s
