Description
Due: Start of Lab Sessions in Week 2 Problem Statement: Using the Eclipse IDE, write a single class Java program named PrintingPatterns that displays the following patterns separately, one below the other, on the computer screen. See the Sample Output below. Use for loops to generate the four patterns. After your program is capable of printing the patterns with a width of 10 characters (as in the sample output) 1. Change your program so that a single numerical value in your code controls the width of the patterns. That is, changing a single “10” to “20” in ONE place in your code causes the patterns to be printed properly with a width of 20 characters (which means you should use a variable to denote the maximum width). 2. Change your program so that a single character value in your code controls the character in the pattern. That is, changing a single “#” to “*” in ONE place in your code causes the patterns to be printed properly with another character. Other requirements: All characters must be printed individually by a single statement (inside a loop) of the form System.out.print(“#”); A statement of the form System.out.println(); can be used to move to the next line. A statement of the form System.out.print(” “); can be used to display a single space for the last two patterns. There should be no other output statements in the program, and no extra line breaks before or after patterns.
