Measuring Time 🕰

Many applications require a very precise time measurement. For this purpose, Java provides static methods in System class. 🔆

1️⃣ - currentTimeMillis(): Returns current time in MilliSeconds since Epoch Time, in Long.
view sourceprint?

long startTime = System.currentTimeMillis();
long estimatedTime = System.currentTimeMillis() - startTime;

2️⃣ - nanoTime(): Returns the current value of the most precise available system timer, in NanoSeconds, in long.

nanoTime() is meant for measuring relative time interval instead of providing absolute timing.

long startTime = System.nanoTime();
long estimatedTime = System.nanoTime() - startTime;

Use explanatory variables 💡

Bad :

const address = 'One Infinite Loop, Cupertino 95014';

const cityZipCodeRegex = /^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$/;

saveCityZipCode(address.match(cityZipCodeRegex)[1], address.match(cityZipCodeRegex)[2]);

Good :

const address = 'One Infinite Loop, Cupertino 95014';

const cityZipCodeRegex = /^[^,\\]+[,\\\s]+(.+?)\s*(\d{5})?$/;

const [, city, zipCode] = address.match(cityZipCodeRegex) || [];

JavaScript Clean Code 🛠

We will read more code than we will ever write. It's important that the code we do write is readable and searchable.💡

Bad :

// What the heck is 86400000 for?
setTimeout(blastOff, 86400000);

Good :

// Declare them as capitalized `const` globals.
const MILLISECONDS_IN_A_DAY = 86400000;

setTimeout(blastOff, MILLISECONDS_IN_A_DAY);

Don't add unneeded context 💡
If your class/object name tells you something, don't repeat that in your variable name.

Bad :

const Car = {
  carMake: 'Honda',
  carModel: 'Accord',
  carColor: 'Blue'
};

function paintCar(car) {
  car.carColor = 'Red';
}

Good :

const Car = {
  make: 'Honda',
  model: 'Accord',
  color: 'Blue'
};

function paintCar(car) {
  car.color = 'Red';
}

🖼 Rescale Image In Java 🖼

An image can rescaled using AffineTransform. First of all, Image Buffer of input image is created and then scaled image is rendered. ✔️

BufferedImage imgSource = 
   ImageIO.read(new File("myImage.jpg"));

BufferedImage imgDest = 
   new BufferedImage(100, 100,
   BufferedImage.TYPE_INT_RGB);

Graphics2D g2d = imgDest.createGraphics();

AffineTransform affinetransformation =
   AffineTransform.getScaleInstance(2, 2);

g2d.drawRenderedImage(imgSource,
    affinetransformation);

ImageIO.write(imgDest, "JPG", 
   new File("outImage.jpg"));

Functions should do one thing 💡

Bad :

function emailClients(clients) {
  clients.forEach((client) => {
    const clientRecord = database.lookup(client);
    if (clientRecord.isActive()) {
      email(client);
    }
  });
}

Good :

function emailActiveClients(clients) {
  clients
    .filter(isActiveClient)
    .forEach(email);
}

function isActiveClient(client) {
  const clientRecord = database.lookup(client);
  return clientRecord.isActive();
}

📦 Macro To Get Array Size Of Any Data Type In C 📦

The following macro will help you in getting the size of an array of any data type. It works by dividing the length of the array to the size of its field. 💡

Code:

#define num(x) (sizeof (x) / sizeof (*x)) 

int  _tmain() {
   int numbers[10] = 
       {1,1,1,1,1,1};

   char *chars[20] =
       {"","","","","","","","",""};

   printf("Size of numbers[10] is %d\n", 
       num(numbers));

   printf("Size of chars[20] is %d\n",
       num(chars));
}

Output:

  Size of numbers[10] is 10 

  Size of chars[20] is 20  

  Press any key to continue . . .

  } else {

  }
}

Good :
