Question

In Parts This Skill Builder will require you to write several functions in which loops will be the focus. In addition, some of these function will require you to design and implement finite state machines. So, let's get started! The template below has a class called SkillBuilder6 with a set of skeleton methods provided. The requirements for each method is provided below Left Triangle In the template below, SkillBuilder6 has a method with the following signature: public static String leftRightTriangle (int height) that returns a string consisting of asterisks in a left-right triangle pattern with a height, height. When the method is invoked as follows SkillBuilder6.leftRightTriangle (5) the result is a string that is equivalent to the following If printed, System.out.println (SkillBuilder6.leftRightTriangle (5)) The result is Invoking the method with a different argument, SkillBuilder6.leftRightTriangle (3) results in, and if printed, System.out.println (SkillBuilder6.leftRightTriangle (3)) results in, Right Triangle In the template below, SkillBuilder6 has a method with the following signature: public static String rightRightTriangle (int height)

Answer 1

public class SkillBuilder6 {

public static String leftRightTriangle(int height)

{

String str = "";

int i, j;

// outer loop to handle number of rows

// n in this case

for(i=0; i<height; i++)

{

// inner loop to handle number of columns

// values changing acc. to outer loop

for(j=0; j<=i; j++)

{

str += "* ";

}

str += "\n";

}

return str;

}

public static String rightRightTriangle(int height)

{

String str = "";

int i, j;

// outer loop to handle number of rows

// n in this case

for(i=0; i<height; i++)

{

// inner loop to handle number spaces

// values changing acc. to requirement

for(j=2*(height-i); j>=0; j--)

{

str += " ";

}

// inner loop to handle number of columns

// values changing acc. to outer loop

for(j=0; j<=i; j++)

{

str += "* ";

}

// ending line after each row

str += "\n";

}

return str;

}

}
