A single JUnit test class can only have a single test method.

Consider the following (supposedly) immutable class: public final class Immutable { private final String string; private final int x; private final List list; public Immutable(String string, int x, List list) { this.string = string; // Line A this.x = x; // Line B this.list = new ArrayList (list); // Line C }  public getList()   { return list; }   // Line D    public getInt() { return x; } // Line E   public getString() { return string; } // Line F } Which line(s) of code is/are a problem with respect tothe immutability of class Immutable (select all correct answer(s) and no incorrect answer(s) to get credit):

What are some best practices when writing doc comments for exposed API elements (select all correct answer(s) and no incorrect answer(s) to get credit)?

It is generally better practice to return null instead of empty collections or empty arrays.

The pattern prints out the half-hollow pyramid, as shown in the test cases below.  Note: You do not need to return anything from the function, just have it print directly.  pattern(5): *   **  * * *  ****** pattern(6): *    **   * *  *  * *   ******* pattern(7): *     **    * *   *  *  *   * *    ********

Online Editor Link (Fork this): LINK Alternatively, you can also use the editor here: LINK The multiplicative persistence of a number is the count of steps needed to reduce it to a single digit by multiplying its digits together repeatedly. For example, the multiplicative persistence of 39 is 3 because: Step 1: 3 × 9 = 27 Step 2: 2 × 7 = 14 Step 3: 1 × 4 = 4 And 4 is a single-digit number, so we stop after 3 steps. Write a function calculate_persistence(num) that takes a positive integer as input and returns its multiplicative persistence. Examples: calculate_persistence(4) should return 0 (it’s already a single-digit number, so no steps are needed) calculate_persistence(39) should return 3 (as shown in the example above) calculate_persistence(999) should return 4 (9×9×9=729, 7×2×9=126, 1×2×6=12, 1×2=2) calculate_persistence(77) should return 4 (7×7=49, 4×9=36, 3×6=18, 1×8=8) Your function should work for any positive integer.

An OTA is providing driving rehab to a client with L hemiplegia who is R hand dominant. The OTA recommends the client to use a spinner knob on the steering wheel. Which of the following would this be considered?

Gradually decreasing the amount of time when performing ADLs with a client with TBI until the client is able to perform all ADLs in a reasonable amount of time
