The system starts vacuuming by activating the two spinning brush motors. The system starts moving the vacuum using a simple, random walk algorithm as follows. The system signals the wheel motors to move forward so that the vacuum moves forward. When the system detects an obstacle, the system rotates the wheels in a randomly selected degree and then moves signals the wheel motors to move forward. The system updates the battery level indicator every 1 minute (when the battery level reaches 15% or lower) The user presses the power button again. The system stops vacuuming by deactivating the brush and wheel motors. It should be noted that if the…arrow_forward

Attach your .java file to the Assignment page. Which of the following five people is the most interesting famous computer scientist? Grace Hopper Ada Lovelace Katherine Johnson Frances Allen Shafi Goldwasser Let’s say that we ask a group of 20 people to vote for which one of the computer scientists is most interesting. Each voter votes for one candidate and, of course, we are interested in who wins. Our data is a matrix with each row representing one of the five computer scientists and each column representing one of the 20 voters. The data in the matrix consists of 1s and 0s. The number 1 in each column represents a vote for the candidate represented by that row. Here is an example matrix (the data matrix is just the numbers). Next to each row is the name of the computer scientist represented by…arrow_forwardusing Java GUI Interface languagearrow_forwardUse object-oriented design to design a class called Rectangle that will receive thelength and breadth of a rectangle, validate the input data and calculate and displaythe area of the rectangle.a Design the class table.b Write an algorithm for each operation.c Write a test or driver algorithm to test the solution.
