Multitasking makes it simple for you to flip between the several applications you have open. Is it possible to run several operating systems on the same computer? That begs the question: yes or no? What alternatives are there for you to consider in the event that this is the case?

Timer Class Concepts tested: Classes 1) Write a class called Timer that models a stopwatch with start, stop, and reset buttons.  It has the following members:     a) -int startTime; // variable tracking when the timer was started (unused when timer is not running). In number of seconds since 1970     b) -int timeOnClock; // variable tracking the time on the clock since last reset in seconds     c) -bool isRunning; //variable tracking wether the clock is running or stopped     d) +Timer(); //constructor, initializes all to zero/false     e) +Timer(bool startNow); // constructur that starts clock automatically if startNow is true     f) +int getTime(); // returns time on clock in seconds. If clock is running, this must also include the time since it was last started     g) +void addTimeToClock(int seconds); // allows manually adding time to the clock     h) +void reset(); // resets time on clock to zero     i) +void start(); // starts clock     j) +void stop(); // stops clock     k)…

Class Connect6State Cloneable Connect6State - A representation of a Connect6  game state. We assume a square grid board size specified to be a positive integer less than or equal to 26. Size 19 is common. The first and second players place pieces on the board that are black and white, respectively. Each piece is placed in an unoccupied grid position. On the first turn, the first player places one piece. Afterwards, players alternate placing two pieces per turn. Play continues until either one player completes a consecutive line of 6 or more of their pieces or no play is possible. The player with 6 or more pieces in a horizontal, vertical, or diagonal line is the winner. If no legal play is possible, the game is a draw Field Detail BLACK public static final int BLACK a constant indicating a black player/piece See Also:Constant Field Values WHITE public static final int WHITE a constant indicating a white player/piece See Also:Constant Field Values NONE public static final…
