Answer 1

Priya I think you know how to take user input in Java so 1st line is done.

For ** which is an exponentiation operator, you can use Math.pow() in Java so the 2nd line is also done.

The rest is a while loop which is pretty straightforward and the // operator just floors the floating value so you can use Math.floor() in Java for that.

Hope you have got some understanding now, kindly make an attempt to write an equivalent code in Java and if you are stuck then someone will surely help you.

Even I'm not a Python programmer, but knowing the basics always helps👍
