# Java learning: How to Calculate Rank Operations

In the case of yesterday's circular area program , we use the power of two to calculate the area of ​​a circle. The power of two can be written by multiplying a variable or number to be raised by two. For example, it can be written But how about a lot of rank? for example There's no way we would multiply that much in the code. Therefore, we need a rank function to calculate it. Java already provides a rank function that can be used at any time. This function has two parameters, namely the number to be raised and the rank.`r2``r*r``4112`

`Math.pow (number, rank);`
Example program, please create a new class named Rank in the meeting package3 . Then follow the following code: The program code above will produce an output: 32, because 2 5will produce 32.
