Solution Review: Compute an Expression Using Maths

Understand how to calculate complex mathematical expressions in Java by using the pow(), abs(), and cbrt() methods. This lesson guides you through step-by-step code to store and compute values with double variables, helping you write accurate and efficient math-based Java programs.

We'll cover the following...

Solution

Java
class HelloWorld {

    public static void main( String args[] ) {

       double x = 55.0;

       double y = 18.0;

       double z = 51.0;

       double answer;

       double sum = Math.pow(x, 2) + Math.pow(y, 2);

       double sub = sum - Math.abs(z);

       answer = Math.cbrt(sub);

       System.out.println(answer);

    }

}

Understanding the Code

Line 7

  • The first step is to create a double type variable called sum.
  • This variable stores the addition result of two expressions.
