- Write a method that prints numbers using the following header:public static void printNumbers(int num1, int num2, intnumberPerLine)This method prints the characters between num1 and num2 with the specifiednumbers per line. Write a test program that prints ten characters per line from 1to 100. Numbers are separated by exactly one space.1. Write the following method that returns the intersecting point between two lines (p1, p2) and (p3, p4): public static Point2D getIntersecting Point ( Point 2D pl, Point2D p2, Point 2D p3, Point2D p4); The method returns null if the two lines are parallel. Write a test program that prompts the user to enter three points and displays the center point. Here is a sample run. (Hint: for finding the intersecting point between two lines, see Programming Exercise 8.31.) Enter x1, yl, x2, y2, x3, y3, x4, y4: 2 2 5 -1.0 4.0 2.0 -1.0 -2.0 The intersecting point is at (2.88889, 1.1111) Enter x1, yl, x2, y2, x3, y3, x4, y4: 2 2 7 6.0 4.0 2.0 -1.0 -2.0 The two lines are parallelQ1. Create a method that transforms a time given in seconds to a String that shows the hours, minutes, and seconds like the time on a digital clock. The String returned from the method shows the time as hours:minutes:seconds. Use the following header: public static String convertTime(int totalSeconds) Write a test program that asks the user for the time in second then displays the time in hours:minutes:seconds. Hint: Use the / operator to get the number of minutes, and the % operator to get the number of seconds left over. Sample runs Enter time in seconds: 150 0:2:30 Enter time in seconds: 2533 0:42:13 Enter time in seconds: 15463 4:17:43
- Exercise 2: The intersection method computes the intersection of two rectangles- that is, the rectangle that would be formed by two overlapping rectangles if they were drawn, as shown at right. You call this method as follows: Rectangle r3 = r1.intersection (r2); Write a program IntersectionPrinter that constructs two rectangle objects, prints them as described in Exercise 1, and then prints the rectangle Intersection object that describes the intersection. Then the program should print the result of the intersection method when the rectangles do not overlap. Add a comment to your program that explains how you can tell whether the resulting rectangle is empty. The random class implements a random number generator, which produces sequences of numbers that appear to be random. To generate random integers, you construct an object of the Random class, and then apply the nextInt (50) gives you a random number between 0 and 49. Use the Random class to construct the two rectangle objects.In a C# Console App do the following Write a method that takes three integers and returns true if their sum is divisible by 3, false otherwise. Write a method that takes two strings and displays the string that has fewer characters. Write a method that takes two bool variables and returns true if they have the same value, false otherwise. Write a method that takes an int and a double and returns their product.Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
- 1. Write the following method that returns the intersecting point between two lines (p1, p2) and (p3, p4): public static Point 2D getIntersecting Point ( Point 2D pl, Point 2D p2, Point 2D p3, Point2D p4); The method returns null if the two lines are parallel. Write a test program that prompts the user to enter three points and displays the center point. Here is a sample run. (Hint: for finding the intersecting point between two lines, see Programming Exercise 8.31.) Enter x1, yl, x2, y2, x3, y3, x4, y4: 225 -1.0 4.0 2.0 -1.0 -2.0 The intersecting point is at (2.88889, 1.1111) The two lines are parallel6. Write a method that reads three strings from the keyboard. Although the strings are in no particular order, display the string that would be second if they were arranged lexicographically. 7. Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a…The area of a rectangle can be computed using the following formula: area = width * height; Write a method that returns the area of a rectangle using the following header: public static double getArea(double width, double height) Write a main method that prompts the user to enter the width and height of a rectangle and displays its area. Input example: 1.2 3.4 Output example: The area of the rectangle is 4.08Create a method that takes a value and tell whether it is null or not.Declared as: boolean isZero (float a)Create a method that takes a value and indicate whether it is positive or negative by a return aBoolean value.Declared as: boolean isPositive (float a)Write a static method that draws an arrow line from astartingpoint to an ending point in a pane using the following method header:public static void drawArrowLine(double startX, double startY,double endX, double endY, Pane pane) Write a test program that randomly draws an arrow line, as shown in Figure.SEE MORE QUESTIONS
