Else
Else is a term often used in programming languages, including but not limited to Java, Python, and C++. It is used in conditional statements, specifically in if-else statements, to specify a block of code to be executed if the condition is false.
Syntax[edit | edit source]
The syntax of an else statement in Java is:
if(condition) { // block of code to be executed if the condition is true } else { // block of code to be executed if the condition is false }
In Python, the syntax is:
if condition: # block of code to be executed if the condition is true else: # block of code to be executed if the condition is false
And in C++, the syntax is:
if(condition) { // block of code to be executed if the condition is true } else { // block of code to be executed if the condition is false }
Usage[edit | edit source]
The else statement is used in decision making in programming. It allows the programmer to specify a block of code to be executed if the condition in the if statement is false. This can be used in a variety of situations, such as validating user input, controlling program flow, and handling errors.
Examples[edit | edit source]
Here is an example of an else statement in Java:
int x = 10; if(x > 10) { System.out.println("x is greater than 10"); } else { System.out.println("x is not greater than 10"); }
In this example, the program will print "x is not greater than 10" because the condition (x > 10) is false.
