Question

All the programs are to be written in java

1. WAP  to print American Flag Using Loop in as minimum code as possible.

1.1 Ask user to enter age, sex ( M or F ), marital status ( Y or N ) and then using following rules print their place of service.
   if employee is female, then she will work only in urban areas.

   if employee is a male and age is in between 20 to 40 then he may work in anywhere

1.2.    Write a program to print all prime number in between 1 to 100.

Answer 1

Solution:

American flag using simple loops:

class Main{
public static void main (String[] args) {
for(int i=0;i<3;i++){
System.out.println("*****=====");
}
for(int i=0;i<3;i++){
System.out.println("==========");
}
}
}

1. class Main{ public static void main(String[] args) { for(int i=0;i<3;i++){ System.out.println("*****====="); for(int i=0;i<3;i++){ System.out.println("=========="); 13 input ... Program finished with exit code o Press ENTER to exit console. I

import java.util.*;
class Main{
public static void main (String[] args) {
int age;
char sex,m;
Scanner inp=new Scanner(System.in);
System.out.println("Enter age");//read inputs from user
age=inp.nextInt();
System.out.println("Enter sex");
sex=inp.next().charAt(0);
System.out.println("Enter Marital status");
m=inp.next().charAt(0);
if(sex=='F')
System.out.println("Urban Areas");//check conditions and print the place of service
else if(sex=='M' && age>=20 && age<=40)
System.out.println("Any place");
else if(sex=='M' && age>=40 && age<=60)
System.out.println("Urban Areas");
else
System.out.println("ERROR");
}

class Main{
public static void main (String[] args) {
int c=0;
for(int i=1;i<=100;i++){//for numbers in range 1 to 100
c=0;
for(int j=i;j>=1;j--){//check for prime
if(i%j==0)
c++;//increment c if it is divisible
}
if(c==2){
System.out.println(i);//print number
}
}
