Programming Tutorials Java Program To Check Perfect Number The entered number is then stored in a variable num. now, to check whether num is even or odd, we calculate its remainder using % operator and check if it is divisible by 2 or not. for this, we use if else statement in java. if num is divisible by 2, we print num is even. else, we print num is odd. we can also check if num is even or odd by. Sum = 1 2 3 = 6 = 6. ⇒ 6 is a perfect number. so, we basically have to find the sum of the proper divisors of a number. 1. using loop to check p erfect number in java. a simple solution is to go through every number from 1 to n 1 and check if it is a divisor and if it is, then add it in the sum variable and at the end check if the sum is.
Programming Tutorials Java Program To Check Whether A Number Is To check the positive and negative of a number, we have implemented the following logic in the java program. if number>0 the number is positive. if number<0 the number is negative. if a number is neither positive nor negative, the number is equal to 0. let's implement the above logic in a java program using the if else statement. Last updated : 29 nov, 2023. a given number can be said palindromic in nature if the reverse of the given number is the same as that of a given number. in this article, we will write a program to check if a number is a palindrome number in java. example of palindrome number. input : n = 46355364. output: reverse of n = 46355364. palindrome : yes. System.out.println(number " is 0."); output. 12.3 is a positive number. if you change the value of number to a negative number (say 12.3), the output will be: 12.3 is a negative number. in the above program, it is quite clear how the variable number is checked to be positive or negative, by comparing it to 0. Similarly, a number that is equal to the reverse of that same number is called a palindrome number. for example, 3553, 12321, etc. to check a palindrome in java, we first reverse the string or number and compare the reversed string or number with the original value. example 1: java program to check palindrome string.

We are given an integer number as an input and our task is to write a java program to check whether that number is even or odd. if a number is divisible by 2, then it is an even number otherwise it is odd. therefore, we can verify a given number is even or odd by dividing it by 2. example scenario 1: input: number = 45; output: result = odd. W3schools offers free online tutorials, references and exercises in all the major languages of the web. covering popular subjects like html, css, javascript, python, sql, java, and many, many more.
