-- conditional statement is a statement that can be true or false.
-- suppose if ask student is pass. (answer yes or no)
-- this type of statement of statement is conditional statement.
#2
In this part we are only discussing about if-else and
in next lecture we are discussing if-else-if ladder, ternary operator and switch statement.
#3
syntax of if-else
-- condition is either true or false after evaluation
-- remember like c and c++, we cannot use number directly as condition of if-else
- if(5) -- not allowed in java
-- you get Type mismatch: cannot convert from int to boolean
if(condition)
{
//code
//either this part execute
}
else
{
//code
//or this part execute
}
#4
example:
if want to check a given number is even or odd then;
int num=13;
if(num%2==0)
System.out.println("Even"); //here we not use braces for single statement {}
else
System.out.println("Odd"); // here we not use braces {}
Note: for single statement braces is not required but for multiple statement it is required.

I was thinking Java is difficult to learn. But you teach every concept friendly , like two friends are taking. Now I think Java is simple and fantastic programming language. Thank you 🙏 @navin reddy sir for teaching us java in simple way. My each concept of java is now clear.

Java is easy if you are well versed in c or c++

"when you use else, there is a compulsion to use if." You have a very excellent way with words. It would be a crime if youre not a PHD. CS professor is one of your callings. Even the explanation of string immutability you have is excellent. Concise and also covering stack/heap memory. Perhaps the best explanations of java concepts on youtube.

Do we not need curly brackets for if and else statements?

@Unknown-rt9vl Жыл бұрын

For larger Statment needed

@hritikyemde1014 Жыл бұрын

If your "if" or "else" block contains more than one statements then it requires curly braces, but if your "if" or "else" block contains single statement then it curly braces are optional

@AnuragRawat01 Жыл бұрын

When you have only one statement after the condition then it's optional to use curly brackets But when you have more than one statement after the condition then it becomes compulsion to use curly brackets 😃 Hope you understand it💯🙏
