Explain why the load is protected if someone were to accidentally flip the battery around from it’s current configuration.

What is this circuit called? What does the circuit do? 

What classification of amplifier is this? What is its conduction angle? How good is its linearity compared to the other classifications? How good is its efficiency compared to the other classifications?

What are the key lifecycle methods of an Activity? Write one sentence for each method detailing when it’s called.  Note: Don’t just parrot the names as descriptive.

What is this circuit/what does it do?

Which states shown on the map had disputed results?

//Write down all the errors in this program class Parent { private int num = 10; public Parent() { System.out.println(“Parent Constructor”); } private void display() { System.out.println(“Display from Parent”); } private void Method() { System.out.println( “Method in Parent”); } public void callPrivate() { Method(); }}class Child extends Parent { private int num = 20; public Child() { System.out.println(“Child Constructor”); } void display() { super.Method(); System.out.println(“Display from Child”); } private void privateMethod() { System.out.println(“Private Method in Child”); } public void callPrivate() { super.display(); }} class Test { public static void main(String[] args) { Parent p = new Child(); Child c=new Parent(); c.num=40; c.display(); c.callPrivate(); }}

If you remove the load from the common emitter amplifier, does the gain go up, down, or have no effect?

// Write the outputs of println statements  class A { int value = 10; A() { this.value += 10; } void printValue() { System.out.println(“A: ” + value); }}class B extends A { int value = 20; B() { super(); this.value += 20; } @Override void printValue() { System.out.println(“B: ” + value); }}class C extends B { int value = 30; C() { super(); this.value += 30; } @Override void printValue() { System.out.println(“C: ” + value); }}class Main { public static void main(String[] args) { A obj1 = new A(); A obj2 = new B(); A obj3 = new C(); obj1.printValue(); obj2.printValue(); obj3.printValue(); System.out.println(“obj1 value: ” + obj1.value); System.out.println(“obj2 value: ” + obj2.value); System.out.println(“obj3 value: ” + obj3.value); }}

Retrieving Images and their IDs Write a function to dynamically retrieve the list of images as resource ids (R.drawable class), and return the list. Remember the Trick or Treat application we implemented in Lab4.  Hint: As part of the TreatController, we implemented this logic but probably statically. public class TreatController {   // Function to fetch all drawable resource IDs dynamically using reflection    private List getDrawableResourceIds() {     // Your code to retrieve the list of resource IDs goes here…     return drawableIds;    } }
