Programming & AI Tips 💡

6 Simple Tips on How to Start Writing Clean Code 👾 1️⃣ Make code readable for people. 2️⃣ Use meaningful names for variables, functions and methods. 3️⃣ Let every function or method perform only one task. 4️⃣ Use comments for clarification ( if really needed ) 5️⃣ Be consistent 6️⃣ Review your code regularly 〰〰〰〰〰〰 #CleanCode @ProgrammingTip

No Need for Temporary Collections, Yield Might Help ✅ Normally when we need to fetch the items from a collection we might create a Temporary List to hold the retrieved items and return. 🌀 Following is the C# code using the temporary list :

public List<int> GetValuesGreaterThan100 
(List<int> masterCollection)
 {
   List<int> tempResult = new List<int>();
   foreach (var value in masterCollection)
   {
     if (value > 100)
      tempResult.Add(value);
   }
   return tempResult;
 }

➖➖➖➖➖➖➖ To avoid the usage of this temporary collection you could choose to use the yield. 🔥 It will yield the result as and when the result set is enumerated. Below is the code using the yield keyword :

public IEnumerable<int> GetValuesGreaterThan100(List<int> masterCollection)
 {
   foreach (var value in masterCollection)
   {
     if (value > 100)
      yield return value;
   }
 }

Compare two string by equals() instead == in java 💡 Use equals() because this method internally checks == plus content equality check. ☑️ [ CODE ]

public class Test {

  public static void main(String[] args) {
    String s1 = "string"; 
    String s2 = "string"; 
    String s3 = new String("string");
    String s4 = s3;
    String s5 = "str"+"ing";
    
    System.out.println("s1==s2 :"+(s1==s2));
    System.out.println("s1==s3 :"+(s1==s3));
    System.out.println(
      "s1.equals(s3) :"+s1.equals(s3)
    );
    System.out.println("s3==s4 :"+(s3==s4));
    System.out.println(
      "s3.equals(s4) :"+s3.equals(s4)
    );
    System.out.println("s1==s5 :"+(s1==s5));
    System.out.println(
       "s1.equals(s5) :"+s1.equals(s5)
    );
  }
}

[ RESULT ]

s1==s2 :true
s1==s3 :false
s1.equals(s3) :true
s3==s4 :true
s3.equals(s4) :true
s1==s5 :true
s1.equals(s5) :true

Do I need to dispose of Tasks ⁉️

“ Task implements IDisposable and exposes a Dispose method.
Does that mean I should dispose of all of my tasks ? ”

No. Don't bother disposing of your tasks.
