Write a program that prompts the user to enter the three points for p0, p1, and p2 and displays whether p2 is on the left side of the line from p0 to p1, right side, the same Line, or on the Line segment. Here are some sample runs:

Explain and print the output of the above code when the parameters to the foo function are passed by reference. Explain and print the output of the above code when the parameters to the foo function are passed by value result. Explain and print the output of the above code when the parameters to the foo function are passed by name.arrow_forward(Java in Eclipse) Write code that finds the sum of two matrices. Use the following method header public static int[][] addMatrix(int[][] a, int[][] b) The rules for adding two matrices are:1. both matrices should have the exact same dimensions (i.e. height and width) – you need to check for this rule in your program.2. both matrices should have elements that have compatible types – you don’t have to add extra code to check this rule in your method as it will only accept int arrays included is a test class and a sample runarrow_forward(Convert decimals to fractions)Write a program that prompts the user to enter a decimal number and displays the number in a fraction.Hint: read the decimal number as a string, extract the integer part and fractional part from the string, and use the Rational class in LiveExample 13.13 to obtain a rational number for the decimal number.

- (Rectangle Class) Create a class Rectangle with attributes lengthand width, each of which defaults to 1. Provide methods that calculatethe rectangle’s perimeter and area. It has set and get methods for bothlength and width. The set methods should verify that length andwidth are each floating-point numbers larger than 0.0 and less than 20.0.Write a program to test class Rectangle.(Java Programming Language)arrow_forward(Please do not give solution in image format thanku) Using Java, Integer variables totalBudget and productCost are read from input. A product costs productCost to make, and a budget is given by totalBudget. Assign remainingBudget with the remaining budget after making as many products as possible.arrow_forwardDo not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics: It contains at least eight characters. It contains at most 12 characters. It contains only alphabetic characters, digits and the underscore (‘_’) character. It does not start with a digit. It has a mix of upper-case and lower-case characters. Your class must contain the following method: public static String checkPassword(String input) This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.arrow_forward

- (GREATEST COMMON DIVISOR) The greatest common divisor of integers x and y is the largest integer that evenly divides into both x and y. Write and test a recursive function gcd that returns the greatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equal to 0, then gcd (x, y) is x; otherwise, gcd (x, y) is gcd (y, x % y), where % is the remainder operator.arrow_forward11.arrow_forward(Needs to write a java program. The imput file that the code will be tested on will be really large, but a code that can work on the provided sample in the picture should work just fine) An image is an array, or a matrix, of pixels (picture elements) arranged in columns and rows. RGB is one of the models used in color pixels. In a color image, each RGB pixel is an integer number which contains the mixture of red, green and blue colors. In this assignment, you will be provided with an image data file, image.dat. The first line in data file contains the height (rows) and width (columns) of the image. The following lines gives the red, green and blue color integer values for each pixel. The following sample.dat is given as an example: (The given example can be seen on the picture down) According to this input file, the image has 4 rows and 2 columns. The pixel at [0][0] has red value 117, green value 117 and blue value 245. Write a Java program that reads from the given input file and…arrow_forward
