Le programme Java multiplie deux nombres flottants

Java example complete set

Dans ce programme, vous apprendrez à multiplier deux nombres flottants en Java, à stocker le résultat et à l'afficher à l'écran.

Example: multiplication of two floating-point numbers

public class MultiplyTwoNumbers {
　　　　public static void main(String[] args) {
　　　　　　　　float first =　1.5f;
　　　　　　　　float second =　2.0f;
　　　　　　　　float product = first　*　second;
　　　　　　　　System.out.println("Calculation result: ",　+　product);
　　　　}
}

When running the program, the output is:

Calculation result:　3.0

In the above program, we have two floating-point numbers1.5f and2.0f stored in variables first and second separately.

Note that we have used f after the number. This ensures that the number is a float, otherwise it will be assigned as a double type.

Then use multiplication*operator, and store the result of multiplying first and second in a new float variable product.

Finally, use the println() function to print the product result on the screen.
