How do you calculate power in Java?
Steps to Find Power of a Number
Read or initialize base and exponent.Take another variable (power) to store the result and initialize it to 1.Using the for loop or while loop, multiply the base by power and store the result into power.Repeat the above step (3) until the exponent becomes 0.Print the result.
Does Java have exponent?
