import java.io.*;
  
class GFG {
    public static void main(String args[])
    {
  
        // initialising variables directly
        int a = 5;
  
        // printing value of a
        System.out.println("The value of a is: " + a);
    }
}

Output:

The value of a is: 5

# Python 3 code to demonstrate variable assignment 
# upon condition using One liner if-else
  
# initialising variable using Conditional Operator
# a = 20 > 10 ? 1 : 0 is not possible in Python
# Instead there is one liner if-else
a = 1 if 20 > 10 else 0
  
# printing value of a
print ("The value of a is: " + str(a))

Output:

The value of a is: 1
