Question

Write a program to print all the 3 digit prime numbers in java

Answer 1

Answer:

• Public class prime number

• public static void main (string args) {

• inter i,m=0, flag=0

Answer 2

Answer:

//Program to print all prime numbers from 100 to 999.

class abc{

public static void main (String ar []){

for(int I=100;I<=999;I++){

int c=0;

for(int j=1;j<=I;j++)

if(i%j==0)

c++;

if(c==2)

System.out.println(I+" is a prime number");

}

}

}

Logic:

• Run I loop from 100 to 999
• Run j loop from 1 to I
• count all the factors of value of variable I
• check if I is a prime number or not (c==2)
• if yes, print that number
