Answer:
Following are the code to this question:
import java.util.*;//import package for user input
public class Main//defining class main
{
public static boolean odd_number_digits(int n)//defining boolean method odd_number_digits
{
if(n>0 && n%2!=0)//defining if block that check value is positive and odd number
{
return true;//return value true
}
else//defining else block
{
return false;//return false value
}
}
public static void sum_odd_digits(int n)//defining a method sum_odd_digits
{
int sum=0,i;//defining integer variable
for(i=0;i<=n;i++)//defining for loop
{
if(i%2!=0)//defining if block for odd number
{
sum=sum+i;//add odd number
}
}
System.out.print(sum);//use print method to print sum value
}
public static void main(String[] args) //defining main method
{
Scanner ox=new Scanner(System.in);//creating Scanner object
int n= ox.nextInt();//defining integer variable for input value
System.out.print(odd_number_digits(n)+ "\n");//use print method to call method
System.out.println("Sum of odd numbers: ");//print message
sum_odd_digits(n);//calling method
}
}

Explanation:
In the above code, two methods "odd_number_digits and sum_odd_digits" are defined in which the first method return type is boolean because it will true or false value, and the second method returns the sum of odd numbers.
In the "odd_number_digits" method, an integer variable passes as an argument and inside the method, if block is used that check value is a positive and odd number then it will return a true value.
In the "sum_odd_digits" method, it accepts an integer parameter "n", and define integer variable "sum" inside the method, which uses the for loop, inside the loop if block is used that counts odd numbers and adds its in sum and print its value.

Explanation:
Logical True and Logical False
These are kinda strange operations. Logical true always results in True and logical false always results in False no matter the premise. These operations are often referred to as “always true” and “always false”.
Binary Operators
Binary operators require two propositions. We’ll use p and q as our sample propositions.
Negation
The negation operator is commonly represented by a tilde (~) or ¬ symbol. It negates, or switches, something’s truth value.
We can show this relationship in a truth table. A truth table is a way of organizing information to list out all possible scenarios.
AND
The AND operator (symbolically: ∧) also known as logical conjunction requires both p and q to be True for the result to be True. All other cases result in False. This is logically the same as the intersection of two sets in a Venn Diagram.
Implication
Logical implication (symbolically: p → q), also known as “if-then”, results True in all cases except the case T → F. Since this can be a little tricky to remember, it can be helpful to note that this is logically equivalent to ¬p ∨ q (read: not p or q)*.
