		int [] myStudentNO=new int[n];
		for(int i=0;i<n;i++){
		    myStudentNO[i]=in.nextInt();
		}
		int countEven=0;
		int countOdd=0;
		for(int i=0;i<n;i++){
		    if (myStudentNO[i]%2==0){
		        countEven++;
		    }
		    else{
		        countOdd++;
		    }
		}
		System.out.print("Your student's ID NO: ");
		for(int i=0;i<n;i++){
		    System.out.print(myStudentNO[i]);
		}
		System.out.println("\nNumber of even numbers: "+countEven);
		System.out.println("Number of odd numbers: "+countOdd);
	}
}

Output
