32) Write a valid Java statement that generates a random value between 1 and 100, inclusive, and assigns that value to randPer. 33) What library must be imported to use the Java random number generator class and its methods? Give the correct import statement needed to ensure that this class is available for use in the program using it. 34) Write a valid method in Java that performs a simulated coin-toss – meaning it returns boolean value of either true...
Java question Q1) Use the following code snippet which generates a random sized array with random contents to complete the following problems: public int [] createRandomArray() { int size = (int) (Math.random() * 10) + 1; int[] array = new int [size]; for (int i = 0; i < array.length; i++) { array[i] = (int) (Math.random() * 10 ) + 1; } return array; } Assignment...
Create a JAVA application which generates 20 random numbers between 1 and 100 and writes them to a text file on separate lines. Then the program should read the numbers from the file, calculate the average of the numbers, and display this to the screen.
Please write in java program Write an application that generates 100 random integers between 1 and 75 and writes them to a file named "file_activity.txt". Read the data back from the file and display the following: The sum of the numbers in the file The average of the numbers in the file The numbers in the file in increasing order To sort an array: int[] arr = new int[20]; Arrays.sort(arr); -- this sorts an array To sort an ArrayList: ArrayList<Integer>...
