Java operators example

Assign '11 * 18' to a 'short' data type named 'answer1'

public class Lecture10 {
    public static void main(String[] args) {
        // TODO: Assign '11 * 18' to a 'short' data type named 'answer1'
    }
}

Java operators example solution

short answer1 = 11 * 18;

Hi there, this is Marius from AlefTav Coding. In this lecture you will learn how to use operators in Java.

Operators are special symbols that you use in order to calculate a result. Some of these operators are: *, /, %, +, -, <, >=, !=, =

The example problem for this lecture states that you must assign '11 * 18' to a short data type named 'answer1'. In other words, you have to store the result of the multiplication, (x) expression, 11 * 18 at a storage location, named answer1.

In my solution, again, I use the Java pattern dataType storageName = value. The requirement says the data type must be short. Then, the storage name must be answer1. Finally, the initialization or assignment must be the expression 11 * 18. (11 multiplied by 18).

Let's examine the program. My class is Lecture10 with a method, main(). The solution code is short answer1 = 11 * 18;

In this lecture you learned how to use operators in Java.

To re-enforce what you have just learned, complete the following coding exercise:

public class Lecture11 {
    public static void main(String[] args) {
        // TODO: Assign ‘40 – 13' to a 'byte' data type named, ‘answer5’
    }
}

My name is Marius from AlefTav Coding. Until next time, KEEP CODING.
