How do you test if a number is a palindrome in Java?

How do you test if a number is a palindrome in Java?

Palindrome number algorithm

  1. Get the number to check for palindrome.
  2. Hold the number in temporary variable.
  3. Reverse the number.
  4. Compare the temporary number with reversed number.
  5. If both numbers are same, print “palindrome number”
  6. Else print “not palindrome number”

How do you check whether a number is prime palindrome or not in Java?

Steps to check PalPrime number We use the “for loop” to check whether the number is prime or not. We also check whether the number is palindrome or not. If the number is both Prime and Palindrome, print “number is a PalPrime number.”. If not, then print “number is not a PalPrime number.”.

How do you find if a number is the power of 2 in Java?

Java Program to find whether a no is power of two

  1. A simple method for this is to simply take the log of the number on base 2 and if you get an integer then number is power of 2.
  2. Another solution is to keep dividing the number by two, i.e, do n = n/2 iteratively.
  3. All power of two numbers have only one bit set.

How do you check the number is palindrome or not?

The algorithm follows 3 steps:

  1. Declare two variables: one stores the given number, and the other stores the reversed number.
  2. Run the do-while loop until the number of digits in the reversed number are equal to the number of digits in the given number.
  3. Check if the reversed number is equal to the given number.

Is palindrome string program in Java?

This is a Java Program to Check whether a String is a Palindrome. Enter any string as input. Now we use for loops and if-else conditions along with equalsIgnoreCase() method to conclude whether the entered string is palindrome or not.

How can you tell if a palindrome is a prime number?

A number is said to be a prime palindrome number if the number is a prime number as well as a palindrome. For example, if we consider a number 101, the number is a prime number as well as a palindrome number. But if we consider the number 13, then it is a prime number but not a palindrome number.

How do you write a power of 2 in Java?

The power function in Java is Math. pow()….PowerFunc1. java:

  1. public class PowerFunc1 {
  2. public static void main(String[] args)
  3. {
  4. double a = 5;
  5. double b = 2;
  6. System. out. println(Math. pow(a, b)); // return a^b i.e. 5^2.
  7. }
  8. }

How do you write a number squared in Java?

Squaring a number in Java can be accomplished in two ways. One is by multiplying the number by itself. The other is by using the Math. pow() function, which takes two parameters: the number being modified and the power by which you’re raising it.

How do you create a palindrome number?

Try this:

  1. Write down any number that is more than one digit. ( e.g. 47)
  2. Write down the number reversed beneath the first number. ( 47+74)
  3. Add the two numbers together. ( 121)
  4. And 121 is indeed a palindrome.
