Article Introduction：Creating a Column with If-Else-Else Conditions in PandasTo create a new column based on an if-elif-else condition, there are two main approaches:Non-Vectorized ApproachThis approach involves defining a function that operates on rows:def f(row): i

Article Introduction：The ELSE clause in PL/SQL specifies the alternative execution path when the condition is false in the IF-THEN-ELSE statement. The syntax is: IF condition THEN code block 1 ELSE code block 2 END IF. Its uses include specifying operations when a condition is false, handling different results, and handling special cases.

Article Introduction：else is used in Java to create conditional statements that execute alternative blocks of code when the first condition is not met: Syntax: if (condition) { ... } else { ... } Working principle: Execute when condition is true if code block, execute else code block when it is false. else is an optional code block. If there is no else and condition is false, the program continues to execute the code after the if statement block.

Article Introduction：else in Java represents the branch of execution when the if condition is false in an if-else structure, used to provide the opposite behavior or handle another situation. Syntax: if (condition) {...} else {...}, usage example: int age = 18; if (age >= 18) {...} else {...}. It differs from if-else if which allows multiple else if conditions, whereas else block provides only one alternative branch.

Article Introduction：IF ELSE statement in Oracle executes different blocks of code based on conditions. It uses IF (condition) THEN...ELSE...END IF syntax, where condition is a Boolean expression, THEN code block executes when the condition is true, and ELSE code block executes when the condition is false. This statement can be nested, and the ELSE code block is optional.

Article Introduction：JavaScript's if else statement is used to execute a code block based on a condition. The syntax is: if (condition) { code block } else { code block }. It can be nested to create complex branching logic. Conditions can evaluate to boolean values, else statements are optional, and additional branch conditions can be added using else if statements.

Article Introduction：The if and else if statements in Java are used to conditionally control the program flow. Their difference mainly lies in the execution order, condition type and execution: Execution order: if takes precedence, else if is checked subsequently. Condition type: if requires a Boolean value, else if can be any Boolean expression. Executability: If the condition is true, it will be executed, if it is false, it will be skipped; else if will only be checked when the if condition is false.
