(Sort ArrayList)
Write the following method that sorts an ArrayList:
public static <E extends Comparable<E>> void sort(ArrayList<E> list)
Write a test program that prompts the user to enter 10 integers, invokes this method to sort the numbers, and displays the numbers in increasing order.
Sample Run
Enter 10 integers: 3 4 12 7 3 4 5 6 4 7
The sorted numbers are 3 3 4 4 4 5 6 7 7 12
Class Name: Exercise19_09
(Algebra: perfect square
)
Write a program that prompts the user to enter an integer
m
and find the smallest integer
n
such that
m * n
is a perfect square.
(Hint: Store all smallest factors of
m
into an array list.
n
is the product of the factors that appear an odd number of times in the array list.
For example, consider
m
= 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So,
n
is 10.)
Sample Run 1
Enter an integer m: 1500
The smallest number n for m x n to be a perfect square is 15
m x n is 22500
Sample Run 2
Enter an integer m: 63
The smallest number n for m x n to be a perfect square is 7
m x n is 441
Class Name:
Exercise11_17
Answer is :
import java.util.Scanner;
public class Squares { public static void main(String[] args) { Scanner scan = new Scanner(System.in); //instantiation of Scanner that will take inputs from the keyboard
//the try catch block below is for trapping error with the input try {…
(Average the major diagonal in a matrix) Write a method that averages all the numbers in the major diagonal in an n * n matrix of double values using the following header:
public static double averageMajorDiagonal(double[][] m)
Write a test program that reads a 4-by-4 matrix and displays the average of all its elements on the major diagonal. Here is a sample run:
1 2 3 4.0
5 6.5 7 8
9 10 11 12
13 14 15 16
Average of the elements in the major diagonal is 8.625
