Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Given the following code, what is the height of "label1"? label1.setBounds(10, 15, 200, 30); A. 10B. 15C. 200D. 30E. Not specified Part 2 - Given the following code, which can add "label1" to a JPanel named "panel1"? JLabel label1 = new JLabel("Hello World !"); A. panel1.Controls.add(label1);B. panel1.add(label1);C. panel1.add("label1");D. panel1.add.Controls(label1);E. label1.add(panel1);

Help me with this java program, thanks!

Semantic Distance is the distance between what people want to do and the meaning of an interface element. Select one: O True O False

TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM.  3. Write an application that reads the radius of a sphere then calculates and displays the circumference, volume and surface area. Use the following formulas, in which r represents the sphere’s radius. Print the output to four decimal places.Circumference = 2 π rVolume = 4/3 π r3Surface Area = 4 π r2 Hint: Section 3.5 of the textbook describes the many methods of the Math class and how they are used. The Math class also contains pre-defined constants like π. Search on the web for how you can use these. Testing: Include test exhibits for inputs that you choose. Make sure you check the results either with a calculator or some other independent source. Hint: Try Google!

21. Which properties will extend a grid item so that it covers multiple rows and columns, specifically the area from row gridlines 3 to 5 and from column gridlines 1 to 3?   Group of answer choices   a. grid-row: 3/5; grid-column: 1/3; b. grid-row: 2/4; grid-column: 4; c. grid-column-start: 3; grid-column-end: 5; d. grid-column-start-end: 1/3; grid-row-start-end: 3/5;

true of false: a) The first step in any programming task is to start coding. b) The only places we would ever want to put a comment in our code are above a method and above a class.
