I am not sure if my coding is wrong (when I compile it, it compiles with no syntax errors) or if I am using BlueJ incorrectly. I am using BlueJ to run my program and when I run it I get the error "Error incompatible types". Just use the BlueJ object creation and testing feature. You do not have to write a TestMatrix class to test the Matrix class. The diagonal formed from the top left corner to the bottom right corner of Integers in the major diagonal of the array 'matrix'. Write a method 'getSumMatrixDiag' that returns the sum of all the Write a method 'getSumMatrix' that returns the sum of all the integers The constructor must also set the rows and cols variables to match the Write a default Matrix class constructor that constructs the 'matrix' array with the following values: The rows and cols will contains values that are less than equal to MAXROWS and MAXCOLS. Private int cols // number of cols to use in matrix We need to use two constants MAXROWS=10 and MAXCOLS=10 to construct 'matrix.' The Matrix class will also need the following attributes: private int rows // number of rows to use in matrix In other words: Index 0: 0, Index 1: 1, Index 2: 2, Index 3: 1, Index 4: 4. Write a program segment so that the elements with even indexes (0, 2, 4 ) are assigned their respective index values and the elements with uneven indexes get the value one. Use the array field that is provided below. Display the resultant array.For my class assignment we need to Write a class called Matrix that contains a private 2-dimensional int array called 'matrix' that can be up to 10 rows by 10 columns maximum. EXERCISE 4: Print the Index of Array in Java. Example:-ĩ) Remove odd numbers from an array Java:- Write Array programs in Java to remove odd numbers from an array. Display results in the given two different formats (write separate programs for them):-ġ1: odd, 12: even, 13: odd, 14: even, 15: oddĨ) Sum of Even and Odd Numbers in Array in Java:- Write a Java program to find the sum of even and odd numbers in an array. Display the sum value. Example:-ħ) Display Even and Odd numbers in an Array:- Write Array programs in Java to display even and odd numbers from a given array of numbers. Take an array, check each element of the array whether is it even or odd and display it. Example:-Ħ) Put Even and Odd Elements in 2 Separate Arrays:- Write a Java program to put even and odd elements of an array in 2 separate arrays. And display both arrays. Take an array, count even-odd numbers, and display the count values. Then sum of array elements = 10 + 20 + 30 + 40 + 50 = 150Īnd the average of numbers = 150 / 5 = 30ĥ) Count Even and Odd numbers in an Array:- Write Array programs in Java to count the even and odd numbers in the given array. Use a method to perform this operation. Take input from the end-user, find the sum and calculate the average. Example:-Ĥ) Find the average of an Array:- Write a Java program to find the average of an array. To display an array you can use the while loop, for loop, for-each loop, or the toString() method given in class.ģ) Find the Sum of Array in Java:- Write Array programs in Java to find the sum of array elements in Java. Take an array, and display it using different approaches. Example:-Ģ) Different ways to Print Array:- Write an array program in Java to display a given array. Let us see Array programs in Java,ġ) Find Length of Array in Java:- Write a Java program to find the length or size of the different array. All the below programs are same as given in the above links, but here you will get the program description with some examples. Read the problem, try to solve it by yourself, and then check the solution. Using custom open-source classes, you will write programs that access and transform images, websites, and other types of data. You will learn to design algorithms as well as develop and debug programs.
