Problem 2 Java program
import java.util.Scanner;
public class Problemb2 {
public static void main(String[] arg)
{
int age;
Scanner sc = new Scanner(System.in);
System.out.println("Enter your Age");
age=sc.nextInt();
if(age>=25)
{
System.out.println("You are elgible to become president of USA");
}
else
{
System.out.println("You are not elgible to become president of USA");
}
}
}
Problem 3 Java program
import java.math.BigDecimal;
import java.util.Scanner;
public class problemb3 {
public static void main(String[] arg)
{
float cost;
float sell;
float result;
Scanner sc = new Scanner(System.in);
System.out.println("Input product Cost price");
cost=sc.nextFloat();
System.out.println("Input product Selling price");
sell=sc.nextFloat();
result= sell-cost;
result =round(result,2);
if(result>0)
{
System.out.println("Seller makes a profit of "+result);
}
else if(result<0)
{
System.out.println("Seller makes a loss of "+ Math.abs(result));
}
else
{
System.out.println("No profile, no loss");
}
}
public static float round(float d, int decimalPlace) {
BigDecimal bd = new BigDecimal(Float.toString(d));
bd = bd.setScale(decimalPlace, BigDecimal.ROUND_HALF_UP);
return bd.floatValue();
}
}
