Suppose you have created a JavaScript event listener that responds to a pointerdown event for the square object by running the graspSquare() function. You want the graspSquare() function to begin by determining the coordinates of the pointerdown event relative to the top-left corner of the browser viewport or window. What should you place in the blank in the following code? function graspSquare(e) {      _____      // additional commands } a. let startingX = e.clientX; let startingY = e.clientY; b. let startingX = e.offsetX; let startingY = e.offsetY; c. let startingX = square.clientX; let startingY = square.clientY; d. let startingX = square.pageX; let startingY = square.pageY;

Use a GUI to open the file and display words Create another class called Word GUI that will be a complete JFrame with a menu bar and menus. There should be two menus: one called File and another called List. The File menu should have the menu items Open and Quit. The List menu should have five menu items: A, E, I, O, U. The content pane of the GUI should have a grid layout of one row and two columns. Clicking on File > Open should allow the user to choose a file. That file should be displayed in the left column, with the lines numbered (starting at 1). When the user clicks on List a choice can be made of one of the five vowels. Clicking on a vowel should list all the words starting with that vowel in sorted order in the right column. Each word should have the line number on which it appeared. Create a class to record the word and its line number Create a class called WordLine that will have two instance variables: a String for the word, and an int for the line number on which the word…
