I want uncommon strings from both of these arrays.can anyone suggest how to do it.

What do you mean by uncommon? Present in one and not the other? — Thiyagu, Mar 24 '18 at 08:02

    String [] array1={"Hardware Docs","Customer Data","Customer Docs","Commit Reviews","Product Planning Docs","Business Operations ","Proprietary"};
    String[] array2={"Hardware Docs","Customer Docs"};

    ArrayList<String> filter1 = new ArrayList<>();

    for(String str1: array1){
        boolean match = false;
        for(String str2: array2){
            if(str1.equals(str2))
                match = true;
        }
        if(!match)
            filter1.add(str1);
    }

but this is soo brute force. If performance is important for you, you should look for better solutions
