In a class named ReadAndEditFile. java, use the following prompt to get the fileName of the input file from the User: "What is the name of your file?" If the File doesn’t exist, do not crash, but instead display "File Not Found " + fileName and repeatedly prompt until the user has entered a valid file name. If the File exists, read from the File. Capitalize the first letter in the file and capitalize the 1st letter after every period and correct the spacing by removing any duplicate spaces so that there is only 1 space between words.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
