    Default Searching arrays

    I need to find elements from an array that are unique.
    The program is supposed to identify the duplicate elements as they are being entered and not count them.
    For example: if I enter 10 then 20 then 15 then 10 then 20. The program is supposed to identify only the unique numbers in this case 15
    I tried to use a linear search method like the one below but this will only compare the elements against one key

    public class LinearSearch{
    public static in linearSearch(int[] list, int key){
    for (int i = 0; i < list.lenght; i++){
    if(key == list [i])
    return i;
    }
    return -1:
    }
    }

    You only need to compare the elements against one key. By that I mean you pseudocode should be along the lines of

        enter value
        if value is not in array { // call a method that checks and returns a boolean
            enter value into array
        }
    }
     
    boolean method
        for each element in array
            if element equals new value
                return ....
            }
        }
        return ....
    }
    Improving the world one idiot at a time!
