How do you find out if a number is a perfect square?

You can also tell if a number is a perfect square by finding its square roots. Finding the square root is the inverse (opposite) of squaring a number. If you find the square root of a number and it’s a whole integer, that tells you that the number is a perfect square.

How do you check whether a number is perfect square or not in Java?

Output 2:

  1. Suppose, n is a number that we want to check.
  2. Create a for loop that executes from 1 to n/2.
  3. Calculate x=i*i, for each iteration.
  4. The variable x has the following three conditions: If x=n, the given number is perfect square. If x>n, n is not a perfect square. Continue if the above two conditions are not true.
