}

public class Window implements Box2{

public int method1(){

return ITEM_CODE;

}

}

public class myFrame{

public static void main(String args[]){

Window w = new Window();

Explanation:

Steps required to solve this problem:

1 - define what characters are "vowels" by assigning them to an array.

2 - create a variable to record the amount of vowels there are in the string.

3 -  convert the input string into a character array and iterate through each character

4 - for each of the character of the string we go through, check if it matches any of the vowels

5 - return true if the vowel count is greater than 1
