Java Program to Find Square Root of a Number

In this tutorial you will learn about the Java Program to Find Square Root of a Number and its application with practical example.

In this tutorial, we will learn to create a Java program to Find square Root of a number using Java programming.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following Java programming topics:

  • Java Operators.
  • Basic Input and Output
  • Class and Object.
  • Basic Java programming.
  • if-else statements.
  • Switch case.
  • Nested if-else Statements.
  • Java Scanner class.

What Is Square root?

Method of Finding “Square Root” is that numbers are multiplying by itself Twice “6 * 6= 36”. Where a square root of a number on getting multiplied by itself gives the original √36 = 6.
A square root of a number a is a number b such that =a.

Java Program to Find Square Root of a Number

In this our program we will create a program to find “Square Root” of a given number . We would first declared and initialized the required variables. Next, we would prompt user to input value.Later in the program we will find square root.

Output

Square Root

In the above program, we have first declared and initialized a set variables required in the program.

  • number = it will hold  given number.
  • temp= it will hold temporary value of a number
  • sr= it will square root of a number.

We going to use the following formula to find the square root of a number.

in our program we have created a method square_root(number), in this method we have written a equation for finding the square root of a number.and for equation we have used do while loop.function returns the square root of a given number to main method

Where we will print the required square root of a given number as shown in image.

In this tutorial we have learn about the Java Program to Find Square Root of a Number and its application with practical example. I hope you will like this tutorial.
