# Find smallest even from array. and also average of even and odd numbers?

package lesson5;

import java.util.Scanner;

``````private static Scanner sc;

public static void main(String[] args) {
sc = new Scanner(System.in);
int i = 0;
double num[] = new double[5];

double evensum = 0;
int oddcount = 0;
int oddsum = 0;

for (i = 0; i < 5; i++) {

num[i] = sc.nextInt();
}

System.out.println(" print even num : ");

}

above mentioned code works. just i couldnot get result- min and max.

Try this.

``````package lesson5;
import java.util.Scanner;

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int [] masarray = new int [10];
int a,b,c,d,f,g,j,m,n,l;

int flag_even =0;
int min_even = 0;
float sum_even=0;
float sum_odd=0;
int total_even=0;
int total_odd=0;

System.out.println("input first  number of array");
a=sc.nextInt();
masarray [0]= a;

System.out.println("input second  number of array");
b=sc.nextInt();
masarray [1]= b;

System.out.println("input third  number of array");
c=sc.nextInt();
masarray [2]= c;

System.out.println("input fourth  number of array");
d=sc.nextInt();
masarray [3]= d;

System.out.println("input fiveth  number of array");
f=sc.nextInt();
masarray [4]= f;

System.out.println("input sixth  number of array");
g=sc.nextInt();
masarray [5]= g;

System.out.println("input seventh  number of array");
j=sc.nextInt();
masarray [6]= j;

System.out.println("input eighth  number of array");
m=sc.nextInt();
masarray [7]= m;

System.out.println("input nineth number of array");
n=sc.nextInt();
masarray [8]= n;

System.out.println("input tenth  number of array");
l=sc.nextInt();
masarray [9]= l;

for ( int i =0; i < masarray.length; i++){
if (masarray[i]%2==0){

if(flag_even==0)//Assigning first even number found in array to min_even to initialize it
{
min_even=masarray[i];
flag_even=1;//Initialization done
}

else if(min_even>masarray[i])
min_even=masarray[i];

sum_even+=masarray[i];//calculates sum of all even numbers
System.out.println("even number = " + masarray[i]);

total_even++;//counting total number of even numbers
}

else
{
sum_odd=masarray[i];//calculates sum of all odd numbers
total_odd++;//counting total number of odd numbers
}
}

if(flag_even==0)
System.out.println("No even number present in array!");
else
{
System.out.println("Minimum Even number in given array is:"+min_even);
System.out.println("Average of Even numbers in given array is:"+(sum_even/total_even));
}

if(total_odd==0)
System.out.println("No odd number present in array!");
else
System.out.println("Average of Odd number in given array is:"+(sum_odd/total_odd));

}
}
