TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

In Java: Write a method that multiplies all elements in the array by 3 and returns it to the main method.

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false

Java programming help please. Main and other class of code is below. Thank you so so much. i have to Write a program that does the following: You have an array of integers with positive and negative values. using one ourArray object (will post code of "ourArrary" below) , and in two loops maximum, How can you reorganize the content of the array so that all negative numbers are on one side and the positive numbers are on the other side. [-3, 2, -4, 5, -6, -8,-9, 7, 13] The output should be [-3, -4, -6, -8, -9, 2, 5, 7, 13] Our array code: public class ourArray<T> implements iQueue{ private T[] Ar; private int size = 0; private int increment = 100; //default constructor @SuppressWarnings("unchecked") public ourArray () { Ar = (T[]) new Object[100]; size = 0; } //constructor that accepts the size @SuppressWarnings("unchecked") public ourArray (int n) { Ar = (T[]) new Object[n]; size = 0; } //constructor that specifies the initial capacity and the increment...
