User Requirements Event handlers are often called event list.pdf
User Requirements
Event handlers are often called event listeners; the terms are often used interchangeably they are
basically the same: The listener listens for the events to happen; the handler is the code in
response to the event. They enable a web page to be more interactive, based on the users
actions.
JavaScript code: For your web page,
A. create and use 5 different JavaScript events EXCEPT click, dblclick, focus, blur, mouseover or
mouseout
B. use the addEventListener() method
C. perform some action for each event addEventListener() method EXCEPT an alert.
D. Display the results and/ or demonstrate each of these items in your HTML file.
Regarding the exceptions: You may use the excepted events and method as long as you satisfy
the required minimums in your code. For example: You may use the click event as long as you
have 5 other different events besides the exceptions listed above.
Theme
Use a vacation theme for your project. All code should be related to any vacation you choose,
realistic or fictional (Trip to the Sun). Use your creativity and have fun with this.

when the average temperature of four consecutive samples meets or exceeds a user-defined
threshold value. A 32-bit unsigned input CT indicates the current temperature, and a 32-bit
unsigned input WT indicates the warning threshold. Samples should be taken every few clock
cycles. A single-bit input clr when 1 disables the alarm and the sampling process. Start by
capturing the desired system behavior as an HLSM, and then convert to a controller/datapath..

Use the following code for the tasks public class Animal .pdf
Use the following code for the tasks:
public class Animal {
private String name;
public Animal ( String name ) {
this.name = name;
}
public String getName ( ) { return name; }
public String speak ( ) {
return name;
}
}
public class Cat extends Animal {
public Cat ( String name ) {
super ( name );
}
public String speak ( ) {
return "Rawr!";
}
}
public class Dog extends Animal {
public Dog ( String name ) {
super ( name );
}
public String speak ( ) {
return "Woof!";
}
}
import java.util.ArrayList;
public class Speak {
public static void main ( String [] args ) {
// Instantiate an object and make it speak.
Animal a = ?;
System.out.println ( a.speak() );
}
}
Task #1:
Examine the contents of the Speak.java class. This file doesn't really contain much. But create at
least 1 animal of either a Dog or Cat type. Then print out the results of the animal speaking. You
should see a "Woof!" or "Rawr!" outputted to the console.
But then modify the Dog or Cat class (whichever you created) such that the speak method returns
the name of the animal, the type of the animal, and then the noise the animal makes. Such that
the output looks something like this:
Barkley (dog): Woof!
OR
Miss Kitty (cat): Meow!
I recommend that you use the getName method to get the name of the animal. Test the output so
that it produces the expected results. The modify the other subclass for animal such that it act
similarly.
Task #2:
Now create your own subclass for animal. Use the Cat or Dog as a guide on how to create the
new subclass. The subclass must be an animal whose first letter of the type is the same first letter
as your name. For instance, if your name is "Zendaya" then you may want to make and animal
subtype "Zebra". Make sure that you make a speak method for the animal such that it makes the
animal's common noise.
Be sure to test the animal out in the same way that you tested for Task #1.
Zebulon (zebra): Yip!
Task #3:
But wait a second. Typical housecats don't really roar (rawr!). That's something that lions do. Make
a copy of the Cat class, naming the copy "Lion" instead. It should do everything a Cat does except
it should be a lion. So really the Lion class should extend the Cat class.
Then go back and change the Cat class so that it says "Meow!" instead of roaring. Test the code
for Cat and Lion in your Speak class to ensure that they both work.
Task #4:
Once you have complete task #3. Create a similar change in the Animal hierarchy for Dog. This
time make a new Wolf class that extends Dog. This new class should do everything a Dog does.
Except when it speaks it should howl: "Awoooooooo!". You can decide how many o's this should
contain. Test the code for Dog and Wolf in your Speak class to ensure that they both work.
Task #5:
We should have a hierarchy of animals that looks like the image at the bottom of the page (except
the Zebra will probably be different). So our last task is to make an ArrayList of all these different
types of animals. Declare and instantiate t.

Use the RTL design process to create an alarm system that sets a single-bit output alarm to 1
when the average temperature of four consecutive samples meets or exceeds a user-defined
threshold value. A 32-bit unsigned input CT indicates the current temperature, and a 32-bit
unsigned input WT indicates the warning threshold. Samples should be taken every few clock
cycles. A single-bit input clr when 1 disables the alarm and the sampling process. Start by
capturing the desired system behavior as an HLSM, and then convert to a controller/datapath..

Use the following code for the tasks public class Animal .pdf
Use the following code for the tasks:
public class Animal {
private String name;
public Animal ( String name ) {
this.name = name;
}
public String getName ( ) { return name; }
public String speak ( ) {
return name;
}
}
public class Cat extends Animal {
public Cat ( String name ) {
super ( name );
}
public String speak ( ) {
return "Rawr!";
}
}
public class Dog extends Animal {
public Dog ( String name ) {
super ( name );
}
public String speak ( ) {
return "Woof!";
}
}
import java.util.ArrayList;
public class Speak {
public static void main ( String [] args ) {
// Instantiate an object and make it speak.
Animal a = ?;
System.out.println ( a.speak() );
}
}
Task #1:
Examine the contents of the Speak.java class. This file doesn't really contain much. But create at
least 1 animal of either a Dog or Cat type. Then print out the results of the animal speaking. You
should see a "Woof!" or "Rawr!" outputted to the console.
But then modify the Dog or Cat class (whichever you created) such that the speak method returns
the name of the animal, the type of the animal, and then the noise the animal makes. Such that
the output looks something like this:
Barkley (dog): Woof!
OR
Miss Kitty (cat): Meow!
I recommend that you use the getName method to get the name of the animal. Test the output so
that it produces the expected results. The modify the other subclass for animal such that it act
similarly.
Task #2:
Now create your own subclass for animal. Use the Cat or Dog as a guide on how to create the
new subclass. The subclass must be an animal whose first letter of the type is the same first letter
as your name. For instance, if your name is "Zendaya" then you may want to make and animal
subtype "Zebra". Make sure that you make a speak method for the animal such that it makes the
animal's common noise.
Be sure to test the animal out in the same way that you tested for Task #1.
Zebulon (zebra): Yip!
Task #3:
But wait a second. Typical housecats don't really roar (rawr!). That's something that lions do. Make
a copy of the Cat class, naming the copy "Lion" instead. It should do everything a Cat does except
it should be a lion. So really the Lion class should extend the Cat class.
Then go back and change the Cat class so that it says "Meow!" instead of roaring. Test the code
for Cat and Lion in your Speak class to ensure that they both work.
Task #4:
Once you have complete task #3. Create a similar change in the Animal hierarchy for Dog. This
time make a new Wolf class that extends Dog. This new class should do everything a Dog does.
Except when it speaks it should howl: "Awoooooooo!". You can decide how many o's this should
contain. Test the code for Dog and Wolf in your Speak class to ensure that they both work.
Task #5:
We should have a hierarchy of animals that looks like the image at the bottom of the page (except
the Zebra will probably be different). So our last task is to make an ArrayList of all these different
types of animals. Declare and instantiate t.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
