Java's arithmetic capabilities are extremely simple and are very easy to use. Remember that all programming languages store values in variables. Look at this piece of code.
int a = 5;
int b = 10;
The above code created 2 variables. Both of them are integers, and they are named 'a' and 'b' respectively. The first (a) was assigned a value of 5, and the second (b) was assigned a value of 10. Let's see how we can add them.
int c = a + b;
This simple statement creates a new variable named 'c.' It is also an integer, and the initial value is set to 'a + b'. Since a equals 5 and b equals 10, c is equal to 15.
Of course, we don't always have to use a variable in order to add. Look at the code below:
System.out.println(12345 + 67890);
This code simply prints the value of 12345+67890 (80235) to the screen. Now, for a working example:
public class AdditionTest {
public static void main(String[] args) {
int a = 5;
int b = 10;
System.out.println("The value of a + b is " + a + b);
}
}

What is Literal in java?
Literals are the values assigned to variables. int num = 10; Here 10 is the integer literal.
How do you select digits in an integer in java?
In Java, you can select digits from an integer by converting it to a string using String.valueOf(int), which allows you to access individual digits via their indices. For example, if you have an integer num, you can do String strNum = String.valueOf(num); and then access digits using strNum.charAt(index). Alternatively, you can use arithmetic operations, such as dividing and taking the modulus, to extract digits. For instance, to get the last digit, you can use num % 10, and to remove the last digit, you can use num / 10.
