Create a Java array FirstArray, type int, length 10. Initialize it with the multiple of 2. Print the array using comma separators. (Hint: Use Arrays.toSring method. You need to import java.util.Arrays package) Print the array with vertical line (|) separator. DO NOT put the vertical line after last element.

Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).

Compare and contrast the array and arrayList. Give at least one example that describe when to use arrayList compared to an array.

Hello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method. Max sure the the last sorted and returned value as the same!

Write a call to Arrays static method equals with arguments arrayl and array2.

Draw a square with a Pentagram hole! The ×ばつ3 square extends from −0.7 to 2.3 on the X axis and from −0.3 to 2.7 on the Y axis. Keep the X and Y arrays named xp and yp, respectively. The template code it's below. I need help with the ellipsis. import matplotlib.pyplot as plt xp = [0, 0.81, 1.62, 1.31, 2.12, 1.12, 0.81, 0.5, -0.5, 0.31, 0] + [None] +[..., ..., ..., ..., ...] yp = [0, 0.59, 0, 0.95, 1.54, 1.54, 2.49, 1.54, 1.54, 0.95, 0] + [None] + [..., ..., ..., ..., ...] plt.axis("equal") plt.axis("off") plt.fill(xp, yp) plt.show() Expected result:

How do you do this? JAVA

We'll go over array notation writing in this part.

We'll go over array notation writing in this part.

In java Define and create a 2-dimensional array of integers with 4 rows and 8 columns. Print the elements of the array in table format (rows and columns). Replace the element in the second row and third column of the array with the value 99.

Try using the ref or out keyword to pass in an array argument and see what happens.

Write a code in java print the largest number in array. Please add comments also and screenshot of output also.
