Math is located in java.lang which is imported by default, no need for the import statement.

You may also want to use System.out.println(result) instead of using printf which needs a format string to output your result.

class Test {
    public static void main(String[] args)  {
        double result = Math.pow(4 , 2);
        System.out.println(result);
    }
}

Everything in `java.lang` is always imported. You don't need to re-import it. – Teepeemm Feb 14 '16 at 20:02

You'll need to use: import java.lang.Math.

Then to complete the task you're after.

for(int i=1; i<=11; i++){  
    System.out.println("Square is: " + Math.pow(i, 2));
    System.out.println("Cube is: " + Math.pow(i, 3));
}

I know this is an old post but..

i don't see any answer to it so for anyone wondering I fixed this issue by changing the name of my file. Check to see if your file name is 'Math'. If it is, change it to something else like 'MathExample' and it should work.

As Grewal_Creator stated above, changing the class name and file from Math to MathExample fixed it. The name Math must be clashing with something else.
