Soution for 16th Question:

import java.util.Scanner;
public class smallestNumber
{
public static void main(String[] args)
    {
        int small=0,num;
        System.out.print("Enter the how many numbers you enter: ");
        Scanner input=new Scanner(System.in);
        int n=input.nextInt();
        for(int i=0;i<n;i++)
        {
        System.out.print(" Enter number-"+(i+1)+": ");
        num=input.nextInt();
        if(i==0)
            small = num; //First number assigning to variable small
        if(num<small) //Here checking the condition if any smallest idetified
          {
           small=num;
          }
}

Solution for 17th Question:

import java.util.Scanner;
public class HelloWorld
{
public static void main(String[] args)
    {
        int num = 2;
        Scanner input=new Scanner(System.in);
        System.out.println("Evennumbers between 2 to 10 are: ");
        do
        {
        if(num%2 == 0)   //Here condition checking if number is divisible by 2 or not.
            System.out.println(num);
            num = num+1;
        }while(num<=10);
    }
}
System.out.println(" Smallest number of entered "+n+" numbers: "+small);
}
}
