So easily and at the same time concisely explained! Thank you

import java.util.Scanner;

public class Switchassignment {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.print("Enter your digit: ");
int i1= input.nextInt();
int i2 = i1%2;
switch(i2) {
case (1):
System.out.println("Your digit is Odd = " + i1);
break;
case (0):
System.out.println("your digit is evem = " + i1);
break;
default:
System.out.println("you type wrong digit");

}
}
}

Oh man if only yanderedev knew about this video. He'd lose his job. Thanks, I was looking for a way to not have to nest if statements :)

I continuously watching your videos from the year 2017...
It's too great...
I learned a lot from your videos..
I have a question to ask you...
Till now you uploaded only for C Programming concepts
When will you upload data structures concepts?
Plz reply me if you see this
Thank you neso academy

I use the condition (ternary) operator because switch cant test values on every case. Adding a switch for every value to test floods the code.
Use this instead:
value1 <test> value2 ? ( ifTrue ) : ( ifFalse ) ;
It seems faster than if-else.
Of course for options and lists and stuff i still use switch.
But the video is useful too!

I do recommend to use if-else for calling "break;" in "for" and "while" loops.

Very good explanation but as per I know switch case bit faster and directly it will jump to the case it will not execute every case as you said even if you not put break statement until and unless case satisfies every line verifies in if else

great vid, easy to follow and to-the-point.

import java.util.Scanner;

class Check {
public static void main(String[] args) {

System.out.print("Enter an integer: ");
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();

switch (n % 2) {
case 0 : System.out.println(n + " is an even number.");
break;
default : System.out.println(n + " is an odd number.");
break;
}
}
}
