25 is a perfect square. 1. The program starts by importing the Scanner class for reading user input. A Scanner object is created to read an integer number entered by the user. 2. It calculates the square root of the given number using the Math.sqrt () method.

Mar 17, 2025 · In Java, we can use the following way to check if a number is perfect square or not. First, find out the square root of the given number. Calculate the floor value of the calculated square root. Find the difference of the floor value with the square root that we have find in step 1. At last, compare the value (that we get in step 3) with 0.

Mar 27, 2023 · Check whether a number is a perfect square or not without finding its square root. Examples: The idea is to run a loop from i = 1 to floor (sqrt (n)) and then check if squaring it makes n. Below is the implementation: print("Yes, it is a perfect square.") print("No, it is not a perfect square.")

May 15, 2023 · A perfect square is an integer that is the square of another integer. In this guide, we’ll explore how to implement a Java program to determine if a given number is a perfect square, covering different approaches and considerations for …

How could I write an if-then statement that checks if an inputted integer is a perfect square or not (i.e. if I took the square root, it would be an integer as well: 4, 9, 16, 25, 36, etc.) in DrJava?

Mar 9, 2023 · Check if a number is a perfect square or not in Java. We will learn two ways, by using Math.sqrt and by using Math.floor with Math.ceil with examples for each.

Learn how to check if a number is a perfect square in Java using Math.sqrt(). This hands-on lab covers calculating square roots, checking for integers, and handling various inputs.

Oct 6, 2021 · We will look at two java perfect square programs: Both of the programs below take the number as user input and process it. The first program uses the math function sqrt () to check for perfect square and the second program uses if..else statement to check.

Feb 23, 2019 · In this tutorial, we will write a java program to check if a given number is perfect square. In this program, we have created a checkPerfectSquare() that takes a number as an argument and returns true if the number is perfect square else it returns false.

Nov 13, 2024 · We learned what perfect squares are, their properties, and how to check if a number is a perfect square using user-defined logic and the Math.sqrt() function. With the implementation of these methods, you can efficiently work with perfect squares in …
