The codes solves the real life problems like Encryption and decryption of Caesar Cipher, Finding common words in a file, a Make Story template and replacing words from a hashmap. 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. This article covers multiple programs in Java that merges two given arrays into the third array. Merge the arrays A and B into a single array C, such that the resulting array is sorted alphabetically. Quick summary: The java codes in this folder is built in BlueJ and completed towards the certification of 'Java Programming: Arrays, Lists, and Structured Data'. 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: Write three methods to process the ArrayList using each of the three loop types: for, foreach and while. The rows and cols will contains values that are less than equal to MAXROWS and MAXCOLS. ArrayList and Loops Create a class named Loops and do the following: Create an ArrayList named Contacts and fill with the following Names: John, Maria, Matt, Chris, Jen (in this order). The following programs require using arrays. Print histogram (with, say 10 bins of size 0.1). For each, the input comes from standard input and consists of N real numbers between 0.0 and 1.0. Private int cols // number of cols to use in matrix The following programs require using arrays. 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 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. 60 Exercises: calculations, convert height into centimeters, loops, program to convert table of miles into km, arrays, program to reverse order of array, strings, lottery numbers generator, text characters count, static methods, program to convert temperature values, classes, lists, etc.
