Reverse integer program in java

Reversing a number implies that the value of the unit of a particular number will become the nth digit value if the number is n digits long and tens digit number will become n-1 th place value number on and so forth. In this article will see a detailed explanation of reverse number in java. To understand the concept further, we are required to take the help of an example. Let us say the number is , then the number is 3 digits long and contains the place value of units, tens and hundreds.

Now when we apply the logic of reversing a number in java, then the units digit, i. Therefore the new number obtained will be , and this will be the reverse number of The logic or the program to write is more or less similar in every programming language, and therefore reading this logic in java should not be a problem.

Now, let us discuss the relevance of a reverse number and why do we actually need it. Sometimes there becomes a need to take out the palindrome of a number.

If you are new to programming and are unfamiliar with the concept of palindrome, then palindrome is the number that is the same even upon reversal. For example, number is a palindrome of So it becomes mandatory to fetch all those values or records which contain palindrome numbers, and there becomes a need to make use of reversing a number in java. Let us understand below with the help of various examples for the reverse numbers in java. But first, let us understand the algorithm behind the reversing of numbers.

In this case, to find out the reverse of a number in java, we are using a while loop, a pre-conditioned loop. Java ArrayList. Popular Examples Check prime number. Print the Fibonacci series. Print Pyramids and Patterns. Multiply two matrices. Find the standard deviation. Reference Materials String. Start Learning Java. Explore Java Examples. Java Examples Check Leap Year. Check Whether a Number is Positive or Negative. Check Whether a Character is Alphabet or Not. The reverse method returns the numeric value obtained by reversing order of the bits in the specified int value.
