Java Logical Operators ( And && Or || )

If You Have To Check Two Variable Values To Given  Two Values, You May Some Time Write Many If Else Statements To Check For Many Variable Values.Without Writing Many If Else Statement You Can Check Many Values That Mean Many If Else Statements In A Single Statement By Using AND or OR Logical Operators.  

You Can Use AND(&&) Logical Operator If You Want To Do Something After Every Operator Gets True.

You Can Use OR(||) Logical Operator If You Want To Do Something After Any Of The Operator Gets True.

Following Example Demonstrate How AND , OR Operators Work.

class EasyCodeStuff {
   public static void main(String args[]){
     
      int No1 = 10;
      int No2 = 20;

      //AND Logical Opearator
      if (No1 == 10 && No1 == 20){
         System.out.println("No1 is Equal To 10 AND No2 is Equal To 20");
      }else{
         System.out.print("No1 is Not Equal To 10 OR No2 is Not Equal To 20");
      }
      
      //OR Logical Operator
      if (No1 == 10 || No1 == 20){
         System.out.println("No1 is Equal To 10 OR No2 is Equal To 20");
      }else{
         System.out.print("No1 is Not Equal To 10 AND No2 is Not Equal To 20");
      }
   }
}    

If Else In Java With ( == , != , < , > , <= , >= Opearators)

In This Example I'm Trying To Explain How If Else Statements Work In Java.
You can Check many Logical Operators With If Else Statements.
There Are Mainly 6 Types.

1. Equal                                       ==
2. Not Equal                                != 
3. Less Than                                <
4. Greater Than                          > 
5. Less Than Or Equal               <=
6. Greater Than Or Equal         >=

Following Example Shows Use Of Operators With if Else Statements

class EasyCodeStuff {
   public static void main(String args[]){
     
      int No1 = 10;

      //Equal Opeartion
      if (No1 == 10){
         System.out.println("No1 is Equal To 10");
      }else{
         System.out.print("No1 is Not Equal To 10");
      }
      
      //Not Equal Opeartion
      if (No1 != 10){
         System.out.println("No1 is Not Equal To 10");
      }else{
         System.out.println("No1 is Equal To 10");
      }
       
      //Less Than Opeartion
      if (No1 < 10){
         System.out.println("No1 is Less Than 10");
      }else{
         System.out.println("No1 is Not Less Than 10");
      }

      //Greater Than Opeartion
      if (No1 > 10){
         System.out.println("No1 is Greater Than 10");
      }else{
         System.out.println("No1 is Not Greater Than 10");
      }

      //Less Than Or Equal Opeartion
      if (No1 <= 10){
         System.out.println("No1 is Less Than Or Equal To 10");
      }else{
         System.out.println("No1 is Not Less Than 10");
      }

      //Greater Than Or Equal Opeartion
      if (No1 >= 10){
         System.out.println("No1 is Greater Than Or Equal To 10");
      }else{
         System.out.println("No1 is Not Greater Than 10");
      }
   }
}
