When using for loops and two-dimensional arrays, the outside loop moves across the rows and the inside loop moves across the columns.
In a two-dimensional array, how should each loop be used?Improved for each loops or layered for loops can be used to iterate across 2D arrays. A 2D array's outer loop typically traverses the rows, whereas the inner loop often covers the columns in a single row. The length of a 2D array indicates the number of rows. length array for a row
Why do we use two for loops with two-dimensional arrays?To better understand an array's contents, think of a two-dimensional array as a matrix with rows and columns. A 2D array can be looped over by first iterating through each row, followed by iterating through each column in each row. We require two loops that are nested inside of one another because of this.

In this assignment, you will build a program using techniques from previous CSS courses that counts unique fractions. No new constructs from our readings are expected, and as such, you can complete this program with just a handful of lines (12-25) of code in just one main function. (But do NOT feel that your code needs to be that short!) Note that the use of methods will improve your design and improve your grade. You will need to use loops, ifs, comments, etc., (in other words, structured programming) to complete this assignment and achieve the outcomes listed below. Included below is a sample execution of your program as well as a list of outcomes your program is to implement; notice reduction of fractions is optional in this version of the assignment. Do NOT build any classes (other than your driver, obviously). You are NOT allowed to use any of Java's built-in abstract data types like ArrayList or HashMap or any of that stuff.
Introduction
Your project is to read in a series of fractions from a text file, which will have each line formatted as follows: "A/B". A sample text file is listed below, and the purpose of your program is to read in each fraction and count the number of occurrences for the current fraction. When all the input is consumed (or as the input is consumed), your program will print out its list of unique fraction and their corresponding count – see the output below (and you may assume no blank lines or misleading characters; see the text file link on the website for one of the actual inputs I’ll use when testing your submission).
Sample Text Input
6/3
7/3
6/3
12/6
Sample Console Output
6/3 has a count of 3
7/3 has a count of 1
NOTE: it is also fine (though not required) if your program simplifies the fractions so that the output is:
2/1 has a count of 3
7/3 has a count of 1
---But either way, 6/3 and 12/6 count as the same fraction, so you do need some mechanism for determining if two fractions that look different are actually the same. The only optional part of the assignment is how you display them in the end.

a. int twoPi = 2*3.14159; / / *holds the value of 6 //* Valid? Why?
b. int twoPi = 3.14159; /* holds the value of two times pi */ Valid? Why?
c. int twoPi = 2*3.14159; /* holds the value of two times pi //* Valid? Why?
d. double twoPi = 2*3.14159; /* // holds the value of two time pi */ [comment] // Valid? Why?
Only the final sentence is true: double twoPi = 2*3.14159;
What is Java?Due to the fact that twoPi is storing pi at 3.14159 after being multiplied by 2. Therefore, the comment is true.
The first sentence's remark is incorrect since the program will fail to compile unless the value is entered as int twoPi = (int)(2*3.14159);
the second statement is also incorrect because pi is never multiplied by 2, hence it is impossible to save pi times its original value.
The final sentence is similarly incorrect since using an int datatype variable to store that value of pi times two would result in a compile-time error.
