Java program for square root or a number in JavaHow to write Java program to find square root of a number is common Javaprogramming exercise which many institute use in there Java course along with and, whichwe have seen earlier. Java program forsquare root is also a popular question during college semester exams and various programming tests. If you arefamiliar with Java API then writing a Java program which can find square rootof number using java.lang.Math class is not difficult. You justneed to pass a double value and it returns a double which is square root of number you passed.

Java Rmi Example

In next section we will see complete code exampleof finding square root of a number from Java program. Another which is very popular and related to programming exerciseis, if you are going to appear in Javainterviews then its worth looking.

As I said its easy to calculate square root using java.lang.Math sqrtfunction but things can be, if interviewer will ask you to write yourown sqrt function during, well its not that easy to write sqrt functionwhich can operatre on double but one trick I use to remember the concept thatsquare of square root must be either less than or equal to number, you can usethat concept to write your own sqrt method in any programminglanguage including Java. Barring, I suggest programmer to usestandard JDK library or open source library like Spring, Apacheetc for such common task because of quality of code and amount of testing doneof those libraries. Anyway here we will see Java program for finding squareroot using API method.
