Lab 5-3 Using a for Loop

The completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. However, in this lab you should accomplish this using a for loop.

1. Open the source code file named NewMultiply. java using Notepad or the text editor of your choice.

2. Write a for loop that uses the loop control variable to take on the values 0 through 10.

3. In the body of the loop, multiply the value of the loop control variable by 2 and by 10.

4. Save this source code file in a directory of your choice, and then make that directory your working directory.

5. Compile the source code file NewMultiply. java .

6. Execute the program. Is the output the same as Lab 5-1?

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() { }
