Expression Evaluation

Write a Java program to compute the specified expressions and print the output.

Specified Expression :
(25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5)

Pictorial Presentation:

Sample Solution:

Java Code:

public class Exercise9 {
 
    public static void main(String[] arg) {
        // Calculate and print the result of a mathematical expression
        System.out.println((25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5));
    }
} 

Explanation:

The above Java code calculates and prints the result of the following mathematical expression:

(25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5)

The code performs arithmetic operations, including multiplication, subtraction, and division, and displays the final result. In this case, the result will be printed to the console.

Sample Output:

2.138888888888889
