Q1. Write Java code to find square root without Math.sqrt()
Ans. 
Use Newton's method to find square root without Math.sqrt() in Java.
• Initialize a variable to store the guess value of square root

• Iterate until the difference between the guess and actual square root is within a desired threshold

• Update the guess value using the formula: guess = (guess + number/guess) / 2
