Else

From WikiMD's Wellness Encyclopedia

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.
