This program outputs a downwards facing arrow composed of a rectangle and a right triangle. the arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width.
(1) modify the given program to use a loop to output an arrow base of height arrowbaseheight.
(2) modify the given program to use a loop to output an arrow base of width arrowbasewidth. use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow base.
(3) modify the given program to use a loop to output an arrow head of width arrowheadwidth. use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow head.
(4) modify the given program to only accept an arrow head width that is larger than the arrow base width. use a loop to continue prompting the user for an arrow head width until the value is larger than the arrow base width.
while (arrowheadwidth < = arrowbasewidth) {
system. out. println("enter arrow head width: ");
arrowheadwidth = scnr. nextint();
}

Technician a says that the radiator usually cools better if the front air dam is removed. technician b says that when a condenser has a leak it can be repaired easily with epoxy. who is correct?

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() { }
