#3.2 Java Tutorial | Ternary and Switch | Selection Statement

In this lecture we are discussing about:
1)Ternary operator
a)syntax
b)example
2)Switch
a)what is use of switch?
b)Can we use other literal than integer in cases ?

#1
Ternary operator:
:- ternary operator is used to check one condition and store the result in variable.
a)syntax
variable = (condition)? expression1 : expression2;

b)examples
e.g
int num=10;
String str= num%2==0?"Even":"Odd";

int num=2;
int num2=3;
int max=num2num1?num2:num1; (use angled bracket between num2 to num1)

#2
switch
switch in conditional statements used to check multiple condition.

a)Use of Switch
Switch is use to check multiple conditions it is just work same as
to use multiple else if.

example: to show syntax
int num=5;
switch(num){
case 2:
break;
case 5:
break;
default:
}

b)Can we use other literal than character and integer like string
:- you cannot use if you have jdk 1.7 or below then you cannot use switch with string
:- you can use switch with int, char, byte, short, enum, string .

example:
String str="shiva";
switch(str){
case "shiva":
break;
case "harsh":
break;
case "muskan":
break;
default:
break;
}

Note: in further lecture we discussed how modern switch works.

Great work doing sir..
Thank you so much

[darpananeja]

You are a very nice mentor!! Please keep educating the psyches around the world!!!

[rajanyadav]

sir can u please give us some coding exercise also, after each lecture for better understanding and in next lecture provide solution of questions, not all but some which u think difficuklt.

[vladanulardzic]

Very practical and easy to understand explanation! Thank you. Keep on...

[JAFFAR]

Sir i simple say that your awesome....explaining..thank u

[silentium]

thanks a lot sir u helped me a lot for my exam

[seventeen]

Is this for Java 8 or 9?
Will you also show new things like Streams and Jigsaw?
And like Rajan said, you should have like 3-5 excersise questions.

Sir, Please upload video on Data Structure like implementation of BST in Java.

[faheemahmad]

R R VERY INTELLIGENT SIR...I WANT TO BE LIKE U

[vyshnavidandagula]

Not only no's Shall we use characters in the ternary statements sir....?

[harshitrawat]

one question for you, can I learn machine learning with java its a better option

[santoshtiwari]

sir, which software are u using. plz tell, i too need to make programs. m in std9

[satyam]

Sir why are you repeating java basic lecture because there are basic java videos in your channel...?

[rehankhaled]

Why ternary operator is written as a comment?

[grasstoucher]

Can u plz make a video on *Iteration through loops*
