  • C#,
  • Java.

Before we getting started, let's first know more about Conditions

What're Conditions?

  • Conditions are a decision-making statement.
  • Perform different actions depending on a boolean condition that may be true or false.

Conditions Type

  • If statement: is used to specify a block of code to be executed, if a specified condition is true.
  • If - else statement: is used to specify a new condition to test, if the first condition is false then it will be redirected to the else part.
  • Logical conditions: Are features of programming languages "conditional statement", we will list them below:-
    •  Less than: a < b
    •  Less than or equal to: a <= b
    • Greater than: a > b
    • Greater than or equal to: a >= b
    • Equal to a == b
    • Not Equal to: a != b

Condition In C#

  • IF Statement.
  • IF-ELSE statement.
  • ELSE-IF Statement.

C# If statement

  •  Use the if statement to specify a block of C# code to be executed if a condition is True.
  • The syntax of  if  statement in C# is:
if (condition) 
{
  // block of code to be executed if the condition is True
} 

if statement in c#

C# If – else  Statement

  • An if statement can be followed by an optional else statement, which executes when the first condition is FALSE.
  • The syntax of If – else  in C# 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 True 
}

if else in C#

C# Else if  Statement

  • Use the else if statement to specify a new condition if the first condition is False.
  • The syntax of  else if  statement in C# is                                  
if (condition1)

{
  // block of code to be executed if condition1 is True
} 

else if (condition2) 

{
  // block of code to be executed if the condition1 is false and condition2 is True
} 

else

{
  // block of code to be executed if the condition1 is false and condition2 is False
}

Conditions In Python

  • IF Statement
  • IF-ELSE Statement
  • ELIF Statement

Python If Statement

  • Use the if statement to specify a block of C# code to be executed if a condition is True.
  • (white space at the beginning of a line) to define the scope in the code
  • The syntax of  if  statement in python  is
if condition  
#block of code to be executed if the condition is True

Python if condition

Python (If–else) Statement

  • An if statement can be followed by an optional else statement, which executes when the first condition is FALSE.
  • (white space at the beginning of a line) to define the scope in the code of if and else
  • The syntax of If – else  in Python 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

if-else in python

Python Elif statement

  • The elif keyword in pythons is the way of saying "if the previous conditions were not true, then try this condition". 
  • Also, make sure that the white space at the beginning of a line is to define the scope in the code of if and Elif.
  • The syntax of If – else in Python is:
if condition
#block of code to be executed if the condition is True 
Elif condition 
# block of code to be executed if the condition is False

elif statement in python


Conditions In Java

  • IF Statement
  • IF-ELSE Statement
  • ELSE-IF Statement

Java If Statement

  • Use the if statement to specify a block of C# code to be executed if a condition is True.
  • The syntax of  if  statement in java is: 
if(condition)  {
// block of code to be executed if the condition is True
}

Java (If-else) Statement

  • An if statement can be followed by an optional else statement, which executes when the first condition is FALSE.
  • The syntax of If – else  in C# 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
}

Java else if Statement

  • Like other programming languages the else if statement in java is to specify a new condition if the first condition is False.
  • The syntax of  else if  statement in Java is
if (condition1)

{
  // block of code to be executed if condition1 is True 
} 

else if (condition2) 

{ 
// block of code to be executed if the condition1 is false and condition2 is true
 } 

else 

{
 // block of code to be executed if the condition1 is false and condition2 is False
 } 

Conclusion

In this post, we have learned how to write different Conditions in C#, Python, and Java programming language.
