         Scanner scan = new Scanner(System.in);
         int min = Integer.MAX_VALUE, max = Integer.MIN_VALUE, i =0; 
      
         System.out.print("Enter the numbers: ");
      
         while(true){
            i = scan.nextInt();
         
            if(i==0)
               break;
         
            if(i%2 == 0){
               if(i< min)
                  min = i;
            }
            
            else if(i > max)
            {
               max = i;
            }
         }
      
      System.out.print("Min even " + min);
      System.out.print("Max odd " + max);
      }
   
   }

keep on reading the numbers one at a time and keep updating the max and min with the condition that max has to be even and min has to be odd...and when user enters 0 print max and min...

#include<stdio.h>
#include<iostream>

using namespace std;
int main()
{
 int i,min=0,max=0;
 
 int flag1=0,flag2=0;
 
 while((std::cin>>i) && (i!=0))
 {
  //check for even no.
  if(i%2==0)
  {
   if(flag1==0)
    {max=i;
     flag1=1;
    }
   else
   { 
    //check if no is greater than max
    if(i>max)
     max=i;
       
   }  
   
  }else{
  //no is odd
  if(flag2==0)
  {
   min=i;
   flag2=1;
  }
  else{
  //check if no is less than min
  if(i<min)
  min=i;     
  
  }                  
        
  }//end else      
 
 }//end while   
 if(min==0)
 printf("No odd number entered\n");   
 if(max==0)
 printf("No even no entered\n");
 
 printf("\n max=%d,min=%d",max,min);
 
 system("PAUSE");
 return 0;


}

#include<iostream>
using namespace std;
int main()
{
	int input,max=0 ,min=INT_MAX;
	cout<<"Enter stream of integers"<<endl;
	
	while(1)
	{
		cin>>input;
		
		if(input == 0)
			break;
		else
		{			
			if(input>max)
				max=input;
			
			if(input<min)
				min=input;			
		}
	}

	if(max%2==0)
		cout<<"Maximum is "<<max<<endl;
	else
		cout<<"Maximum number is not an even number"<<endl;
	if(min%2==1)
		cout<<"Minimum is "<<min<<endl;
	else
		cout<<"Minimum number is not an odd number"<<endl;

	return 0;
	
}

Here is a working code in C++:

#include <cstdio>
#include <iostream>

using namespace std;

int main()
{
    int n, max, min, flag1, flag2;
    n=1;
    while (n!=0) 
    {
        cin>>n;
        if (n==0)
        {
            break;
        }
        if (n%2==0 && flag1==0)
        {
            max=n;
            flag1=1;
        }
        else if (n%2!=0 && flag2==0)
        {
            min=n;
            flag2=1;
        }
        else if(n%2==0 && n>max)
        {
            max=n;
        }
        else
        {
            min=n;
        }
    }
    cout<<"max in even numbers: "<<max<<endl;
    cout<<"min in odd numbers: "<<min<<endl;
    return 0;
}
