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

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;
   }
 }

Access Modifiers 🤷🏻‍♂️🚫

Public 🌎

Using Public, an event or a variable can be accessed from outside of the class, where it belongs.

And also from the outside of the assembly.
〰〰〰〰

Private 🔒

It restricts the use of methods and variables only within the class itself.

It can't be used from outside of the class.

As you declare a private constructor of a class, that class can't be accessed from outside that class, you can't create an object of that class.
〰〰〰〰

Protected ⛓

This allows variables and methods to access from that class and the sub class of the class.

That means that methods can be accessed within that class and from the classes, which actually inherit that class.
