How To Raise a Number To a Power in Java

This is one of the articles from our Java Tutorial for Beginners.

Your Task:

You have to write a method, raising a number to the third power. For example:

Solution:

public class Test{
	static int cube(int a){
		return a*a*a;
	}	
 
	public static void main(String[] args){
		System.out.println( cube(2) );
	}
}

public class Test{

static int cube(int a){

return a*a*a;

}

public static void main(String[] args){

System.out.println( cube(2) );

}

If you run this code on your computer, you will see the following in your console:

Commentary:

First of all, you have to find out the formula of raising a number to the third power. As you see, the formula will look like this a*a*a:

That's why we wrote a method with the help of these lines of code:

static int cube(int a){
		return a*a*a;
	}

static int cube(int a){

return a*a*a;

}

And then we called the method for the number 2:

public static void main(String[] args){
		System.out.println( cube(2) );
	}

public static void main(String[] args){

System.out.println( cube(2) );

}

As a result, we've got the number 8 in the console.
