Write a method called printDesign that produces the following output. Use nested for loops to capture the structure of the figure. -----1 ----333-- ---55555--- --7777777-- -999999999-
Write a Java program called SlashFigure that produces the following output. Use nested for loops to capture the structure of the figure. !!!!!!!!!!!!!!!!!!!!!! 1\!!!!!!!!!!!!!!!!!!// \\\\!!!!!!!!!!!!!!//// \\\\\\ !!!!! !!!!!////// 11!!!!! /// \ww.!////////// $!!!!!!!!!!!!!!!!!!!!!! 1\!!!!!!!!!!!!!!!!!!// \\\\!!!!!!!!!!!!!!//// \\\\\\ !!!!! !!!!!////// 11!!!!! /// \ww.!//////////$
Modify your SlashFigure program from the previous exercise to become a new program called SlashFigure2 that uses a global constant for the figure’s height. (You may want to make loop tables first.) The previous output used a constant height of 6.

Complete the following code, replacing the "FINISH ME" parts with your own code:to produce the following output:2 times 1 = 22 times 2 = 42 times 3 = 62 times 4 = 8 public class Count2 { public static void main (String [] args) { for (int i = /* FINISH ME */) { System.out.println (/* FINISH ME */);
Assume that you have a variable called count that will take on the values 1 , 2 , 3 , 4 , and so on. You are going to formulate expressions in terms of count that will yield different sequences. For example, to get the sequence 2 , 4 , 6 , 8 , 10 , 12 , ... , you would use the expression (2 *

Suppose that you have a variable called line that will take on the values 1, 2, 3, 4, and so on, and a class constant named SIZE that takes one of two values. You are going to formulate expressions in terms of line and SIZE that will yield different sequences of numbers of characters. Fill in the
