( Hint: Please DO NOT USE selection or loop statements! )

1.1.6 Modify UseArgument.java to make a program UseThree.java that takes three names as command-line arguments and prints a proper sentence with the
names in the reverse of the order given, so that, for example,
java UseThree Alice Bob Carol prints Hi Carol, Bob, and Alice.
public class UseArgument { // UseArgument.java public static void main (String[] args) {
System.out.println( “Hi, ” + args[0] + “. How are you?” );
}
}

1.2.28 Order check. Write a program that takes three double command-line arguments x, y, and z and prints true if the values are strictly ascending or escending ( x < y < z or x > y > z ), and false otherwise.
1.2.30 Uniform random numbers. Write a program that prints five uniform random numbers between 0 and 1, their average value, and their minimum and maximum values. Use Math.random(), Math.min(), and Math.max().
1.2.34 Three-sort. Write a program that takes three integer command-line arguments and prints them in ascending order. Use Math.min() and Math.max().
1.2.35 Dragon curves. Write a program to print the instructions for drawing the dragon curves of order 0 through 5. The instructions are strings of F, L, and R characters, where F means “ draw line while moving 1 unit forward,” L means “ turn left,” and R means “turn right.” A dragon curve of order n is formed when you fold a strip of paper in half n times, then unfold to right angles. The key to solving this problem is to note that a curve of
order n is a curve of order n-1 followed by an L followed by a curve of order n-1 traversed in reverse order, and then to figure out a similar description for the reverse curve.
