    When programming, you will need to write codes that perform actions. These actions can be anything from displaying a message on the screen or opening a new window on the screen.

    To perform these actions, you will need to write codes that execute specific commands. These commands can be something like moving an object on the screen or changing the color of the screen.

    These commands are called methods, and they require some input and output. A method receives input data and outputs output data as a result of executing the command.

    There are three parts of a method: definitions, declarations, and implementations. Today, we will only be discussing definitions-the structure of a method definition and how to write your own.

    Syntax for method add

    write the definition of a method add, which receives two integer parameters and returns their sum.

    To write the definition of a method, you must first know the syntax. A method definition starts with the word “def”, followed by the name of the method, then enclosed in braces.

    Following this, you must write a list of parameters the method accepts, then a vertical line, then the code that is run when the method is called, and finally ends with the word “return” followed by what is returned.

    So in general, it looks like this: def nameOfMethod(param1: value1 type param2: value2 type) -> return type.

    For example, let’s write the definition of our add() method: def sum(a: int = 0, b: int = 0) -> int { return (a + b) }.

    Examples of using method add

    Now that add is defined, you can use it. The following examples show different ways to call the add method and receive the sum of two integers.

    Implications of using methods

    write the definition of a method add, which receives two integer parameters and returns their sum.

    Methods are a fundamental part of almost every program. Almost every program you use on a daily basis has many methods that perform different tasks to get the job done.

    Applications like Gmail, Instagram, and YouTube all have different methods for performing actions. For example, in Instagram, you can only post photos or videos, not both at the same time. This is because of the way they designed their app.

    In Gmail, you cannot send money through the app, but you can invert the color of the email so that it looks like you are writing on a whiteboard. These are very specific tasks that are enforced by the developers.

    In general, methods allow for more control over what happens in a program. Because they are self-contained pieces of information, they can be tested and corrected more easily.

    Method parameters

    write the definition of a method add, which receives two integer parameters and returns their sum.

    When writing methods, you can require the method to receive specific data with what is called a parameter. A parameter is defined as a value or set of values that a method receives when it is called.

    For example, in the above example, the sum method was called and required two integer parameters. When the method was executed, it received values for a and b and then computed the sum of these values.

    Parameters are named values that are passed into a method when it is called. The name of the parameter determines what data type the parameter requires. There are several different data types for parameters, each with their own limitations.

    Parameters can be declared before or after the code for the method itself. Generally, it is best to declare all parameters before any code so that viewers can understand what parameters are needed to use the method.

    Return type

    write the definition of a method add, which receives two integer parameters and returns their sum.

    A method can also specify what type of value it will return. This is called the return type and it can be any data type, such as integer or string .

    When a method returns a value, execution passes back to the point where the method was called. The returned value is used in place of the call to that method.

    For example, imagine we have a method that adds two integers and then returns the sum. If we call this addMethod() function on two integers, 5 and 10, then it will return 15 as its result. We could then assign this result to another variable:

    int sum = addMethod(5, 10); // Calls the ‘addMethod()’ function with arguments ‘5’ and ’10’ int sum = addMethod(); // This is also a valid way to call the function int sum = addMethod(5, 10); // Both of these are equivalent // to // assigning the returned value ’15’ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 … 607 608 609 610 …

    Example using the method add()

    write the definition of a method add, which receives two integer parameters and returns their sum.

    Now, you will create a method add() that receives two integer parameters and returns their sum. You will do so by typing the following into your console:

    add() {

    let a = this.a; // this refers to the instance of the Aircraft class, in this case the instance being modified by add()

    let b = this.b; // same thing here!

    return a + b; // Add the values of a and b together and return that value.

    Comparing to an interface

    write the definition of a method add, which receives two integer parameters and returns their sum.

    A method can be defined to accept parameters of a specific data type and return a specific data type. When this is done, the method is restricted to work with only that data type.

    For example, a method that sums two integers can be defined as taking in two integers and returning an integer value. The method itself would then define what happens to the two integers summed and how the integer value is returned.

    When working with instances of classes, this restriction on methods helps enforce the properties of that class. For example, if a class is defined as holding only integers, then any methods that it has cannot accept or return any other data types.

    Interfaces can also be defined with methods. Then, classes that implement the interface must implement all of its methods. Methods in interfaces are also restricted to accepting and returning specific data types.

    When to use a method

    write the definition of a method add, which receives two integer parameters and returns their sum.

    Methods are a common way to separate logic in your code. Methods allow you to create new functions that you can call from other parts of your code.

    For example, a method would be define the term homeless , then define several sub-definitions such as poor , shelterless , and lack of permanent residence .

    You could then call one of these definitions via a method. You would do this by calling the method name, passing any required parameters, and receiving the returned value.

    In programming languages, methods are very similar. You define a method with some parameters and a function body that does something. The only difference is the syntax for calling the method.

    There are many reasons to use methods in your code. One reason is to keep related code together in one place so that it is easier to manage and maintain.
