Add Fractions points Let's Go! In this program you will initialize 4 integers that represent each part of two fractions, namely the numerator and denominator of the first fraction and the numerator and denominator of the second fraction Your program should add the two fractions and print out the result For example, a sample program run might look like this The numerator of the first fraction is 1 The denominator of the first fraction is 2 The numerator of the second fraction is 2 The denominator of the second fraction is The sum of 1/2 + 2/5 - $10 Note you do not need to reduce these fractions. Be sure to test your code for postive and negative integers by changing the values of your Initialized variables. Remember, if you have two fractions you add them with ad. bd

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
