You have declared a single dimensional array of type int using the following code: int [] MyInt = new int [10]; You are attempting to initialize all of the arrays segments with a for loop using the following code: for (int x = 0; x <= 10; x++) { MyInt[x] = x; } What will happen when you attempt to compile the program that contains this code?

you assign a value to the primitive variables x and y as indicated below. Which declaration for z must be used for this code to properly compile? byte x = 3; byte y = 2; // insert declaration for z here z = x + y;
