Can we use the ternary operator without assignment?
You cannot use the Java Ternary Operator alone as a stand-alone statement. So don’t write a ternary operator without an assignment operation. Also the return value is essential. You cannot put null return method calls inside branch expressions of a ternary operator.

How is the conditional operator used in decision making?
Here is a simple example of decision making using if and else: int a = 10, b = 20, c; if (a < b) { c = a; } else { c = b; } printf("%d", c); This example is longer than 10 lines, but that is not necessary. You can write the above program in just 3 lines of code using a ternary operator.
When would you use a conditional operator?
Conditional operators are used to evaluate a condition that is applied to one or two Boolean expressions. The result of the evaluation is true or false.
Is it possible to use a conditional operator instead of a conditional IF statement?
Conditional branching: yes, ‘?’ Sometimes, we need to perform different actions based on different conditions. To do that, we can use the if statement and the conditional operator ? , which is also called the “question mark” operator.
What is the ternary operator in Java?
Java’s ternary operator allows you to write an if statement in one line of code. A ternary operator can evaluate to true or false. Returns a specified value depending on whether the statement evaluates to true or false.
Which is better conditional or if-else?
If the condition is preferred in case the program needs to be executed only in true block. In this case, it is necessary to work to use the ternary operator. The nested ternary operator is not readable and cannot be easily debugged. If else is more readable and easier to debug in case of a problem.
Is the conditional operator faster than if-else?
Yes, it matters, but not for the performance of the code execution. Faster coding (performance) is more relevant to loops and object instantiation than simple syntactic constructs. The compiler must handle the optimization (it will all be on top of the same binary!)
When to use conditional operators in variable assignment?
In some scenarios, where there are if-else conditions in variable assignment cascade. We can use chained conditional operators to replace cascading if-else conditions on a single line by including a conditional expression as a second statement. Let’s take the following example of a cascading/nested if-else statement.
How is the conditional operator similar to the if else statement?
It is similar to the if-else statement. The if-else statement takes more than one line of statements, but the conditional operator completes the same task in a single statement. The conditional operator in C is also called the ternary operator because it operates on three operands. The operands can be an expression, constants, or variables.
How is the conditional operator similar to the ternary operator?
Since the conditional operator works with three operands, it is also known as the ternary operator. The behavior of the conditional operator is similar to the ‘if-else’ statement since the ‘if-else’ statement is also a decision-making statement. Meaning of the above syntax.
How to conditionally assign a value to a variable?
If ‘x’ is 0, assign the value ‘a’ to the variable ‘y’ Otherwise (if ‘x’ is 1) assign the value ‘b’ to the variable ‘y’. Note: – You are not allowed to use any conditional operator (including the ternary operator) or any arithmetic operator (+, -, *, /). Recommended: Test your approach in {IDE} first, before moving on to the solution.
