To write a Java expression for the volume of a sphere using the given formula, you can use the Math.pow() function to raise the radius to the power of 3, and then multiply it by the constant value 4/3 multiplied by π.
Here is the Java expression:
```java
double volume = (4.0 / 3.0) * Math.PI * Math.pow(radius, 3);
```
In this expression, `radius` is a variable of type `double` representing the radius of the sphere. The Math.pow() function is used to calculate the cube of the radius, and the result is multiplied by the constant value (4.0 / 3.0) and π to calculate the volume of the sphere. The result is stored in the variable `volume` of type `double`.
