Write a java program to find the sum of all the prime numbers less than a given natural number N. The main purpose of this interview question is to check the programming sense and capabilities to check how good you are to convert existing logic into code
println("Not a prime number "); } } Output: 1 2 3 Enter a number 7 prime number Find Prime Numbers Between 1 to n 1) We are finding the prime numbers within the limit. 2) Read the “n” value using scanner object sc.nextInt()and store it in the variable n. 3) The for...
Enterany number:1919isaPrimeNumber Output 2: Enterany number:66isnotaPrimeNumber You can also usewhile loopto check the prime number: Just replace this part of the code in above program: for(inti=2;i<=num/2;i++){temp=num%i;if(temp==0){isPrime=false;break;}} with this: inti=2;w...

This java program will read an integer numbers and find its prime factors, for example there is a number 60, its primer factors will be 2, 3 and 5 (that are not divisible by any other number).package com.includehelp; import java.util.HashSet; import java.util.Scanner; import java....
At the end when the algorithm terminates, all the numbers in the list that are not marked are the prime numbers. Here’s what the code looks like: publicstaticList<Integer>sieveOfEratosthenes(intn){booleanprime[] =newboolean[n +1]; Arrays.fill(prime,true);for(intp=2; p * p <= n;...
return b1;public static void main(String args[])你显然在函数体内部开始定义另外一个函数了，return b1后面应该少了}
package com.as400samplecode; public class CheckMyNumber { public static void main(String[] args) { boolean even = false; boolean prime = true; int myNumber = Integer.parseInt(args[0].trim()); if(myNumber % 2 == 0){ even = true; ...
