In this lecture we will learn:
- What are relational operators?
- AND operator
- OR operator
- NOT operator
If we need to combine the result of two or more relational operators, then we use logical operators.
- We use logical operator in between two or more results of relational operators.
- AND operator (&&), OR operator (||) and Not operator (!) are logical operators.
1) In case of AND Operator:
- If both are true - true
- If one is true and other is false - false
- If one is false and other is true - false
- If both are false - false
* If first condition is false then it will not check for the another one and it will increase the execution time.
Thus, because of its less time it is known as short- circuit.
2) In case of OR Operator:
- If both are true - true
- If one is true and other is false - true
- If one is false and other is true - true
- If both are false - false
* If first condition is true then it will not check for the another one and it will increase the execution time.
Thus, because of its less time it is known as short- circuit.
3) In case of Not Operator:
- It is basically used to reverse the things.
It means if result is false, it will do true.
If the result is true, it will do false.
* Not operator just do the opposite.
- We can use as much logical operators as we want in between the relational operations.

00:01 Logical operators in Java allow you to combine multiple conditions 01:30 Logical operators in Java allow computers to make decisions based on multiple conditions. 02:57 Logical operators in Java 04:22 Logical Operators in Java: And, Or, Not 05:46 Logical operators in Java allow for short circuiting, saving time in the evaluation. 07:08 Implementing logical operators in Java 08:27 Logical AND (&&) operator returns true only if both conditions are true 09:55 Logical operators in Java allow for combining multiple conditions

Learned same thing in phython..thanks bro

[@fifaham]

@1:38 You may envision "AND" operator as two switches connected in series, and "OR" operator as two switches connected in parallel. If "AND" is used then both the switches must be ON to produce an active output. If "OR" operator is used then one, or more, of the switches need to be ON to produce an active output. That was from the basic electric circuit perspective. The inverting logic "NOT" is like using an inverting BJT transistor: common Emitter, with input at the Base and output at the Collector (for electrical engineers).

i love this! should help people to visualise it even better if it wasnt clear yet!

[@user-zt5lt4vb5x]

Your explained it was very good sir thank you sir

[@mansikalyankar9834]

You explained it really very well🥹😄

[@rutulkarbhari4963]

even if my condition is true and my code is written right, my output is always giving me false. Why? i tried most of the conditions but the output is always FALSE.

[@ankitsrivastav273]

I had study AND OR NOT gate operation in class 12 phy chapter - semiconductor and logic gates😊

[@mc_6737]

sir in the previous videos you mentioned only class demo..... but here you have mentioned public class demo what is the difference between class and public class sir

[@DHHcovers]

9.59 me and Phil condition false for bhi true aya

[@simonason9342]

What is the diffrence between "public class" and just "class"?

[@user-ld7lg6ch2y]

if we do not specify any modifier then JVM considers it as default access modifier so public class is public with access modifier public class means default with default modifier;

[@mannepallibalaji8786]

class mean it is a default class Which cannot be accessed in other classes Whereas public class can be accessed in any class of the package....

[@Xtreme_Gamer01]

​@@user-ld7lg6ch2y thnx❤❤

[@Actiontitanium]

genuine gajini

[@Mahesh-cw4ix]

there is mistake in that and false false make false not true

[@praveenreddyperam8482]

it is correct only no in given descruption
