This is a simple Java program to find the prime number. A prime number is a number which is greater than 1 and only divisible by 1 or itself. Following is the first 10 prime numbers:
1 | 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 |
In this program, I have taken number as variable to hold the number which will be checked whether it is a prime number or not.
Copy the below java program and execute it with the help of Java compiler.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | public class PrimeNumberExample{ public static void main(String args[]){ int i,m=0,flag=0; int number=11;//it is the number to be checked m=number/2; if(number==0||number==1){ System.out.println(number+" is not prime number"); }else{ for(i=2;i<=m;i++){ if(number%i==0){ System.out.println(number+" is not prime number"); flag=1; break; } } if(flag==0) { System.out.println(number+" is prime number"); } }//end of else } } |
11 is prime number
