Python nested if..else in one line. Java Conditional Operator - The Java Conditional Operator selects one of two expressions for evaluation, which is based on the value of the first operands.
Fun fact: It's properly called the conditional operator .

You don't get improved performance by having fewer lines in your program. It's called nested if...else statement. Interested in saying a lot while writing a little?
Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesI do have a "main" return for the overall method: return; which just exits the function.Also my function doesn't need an "else" -- nor does every "if" in java is necessarily needed to be accompanied by an else: This wouldn´t compile either, as of my guess, it would throw you a compiler error Like the answers say, to use a ternary operator you need to know what you're going to return if neither one of those is 0.
You can see how the "then" and "else" of an if/else pretty much map directly into the second and third operands of the conditional.
João Miguel Proposed as answer by JMCF125 Monday, October 22, 2012 7:44 PM We can also use ternary expression to define nested if..else block on one line with Python. It is also called ternary operator because it takes three arguments.
And from this, it easy to write it just like a ternary using if - else if - else like Thanks for the added explanation! If you have a multi-line code using nested if else block, something like this: if condition1: expr1 elif condition-m: expr-m else: if condition3: expr3 elif condition-n: expr-n else: expr5

How do I write the following 2 line if-statments into one single line of code:I want to learn how to write it in the Ternary-Operator format:but I don't have an "else" in my example PLUS i have two "if" statements so it's confusing me.Is it possible to combine these 2 if-statements into one line of code?In order to write this with the conditional operator, we Without that final value, you cannot write this with a conditional operator.Thanks for contributing an answer to Stack Overflow! In this tutorial, we're going to demonstrate how to implement if/else logic with Java 8 Streams.
It was used to "jump out" of a switch statement..
Here's a program to find largest of 3 numbers: Example 4: Nested if...else Statement Summary: This tutorial shares examples of the Java ternary operator syntax.. What I like about the (chained) ternary operator is that it very clearly communicates that it's calculating *exactly* one value, for exactly one purpose (assigning it to a variable, returning it, whatever).
... You can nest else if...else in the similar way as we have nested if statement.

Much of the time, attempts to squeeze things into fewer lines of code result in programs that are harder for another person to figure out.Just to point out that in the comment, OP says he as a return at the end so this match the answer.
Java Nested if..else Statement.
We can take a look at this article to catch up on the Java 8 Stream basics. your coworkers to find and share information. That's something an if-else-chain doesn't communicate - you have to look very carefully to be sure. But as we see in the Apple bug, if one were to accidentally attempt to add a second statement to the Many coding styles recommend just using curly braces, even for one line If the statement you’re guarding is small, and not worth the extra heft of curly braces, just put it on the same line.As a bonus, this is how it’s done in Ruby, note how they came up with this idea first☺ The break statement can also be used to jump out of a loop..

The opening brace should be at the end of the line that begins the compound statement; the closing brace should begin a line and be indented to the beginning of the compound statement. In Java, it is also possible to if..else statements inside a if..else statement.
This helped me understand Ternary/conditional operations better.
The do/while loop is a variant of the while loop.
", I'm sure that no; but you can omit the curly braces. Apple’s bug was caused by a common feature of C and languages that inherited its syntax (e.g.
