Question

I have a program that relates to a database. I start out my program by inserting a row using the following command.

    long id = db.insertMajor(null, null, null, null); 

it works perfect. I than alter the information but lets ignore that since for the time being I commented out all those lines. Now I want to check and see if it is null which is should be. If it is not null than I would like to check a checkbox. if it is null than I want to leave the box unchecked. So far I have this line to test.

    String change = db.getMajorTitle(value).getString(1);
    if (change.equals(null)) {
    filled = false;
    }

the filled boolean will check the box or not. If the database field is filled or not I always get a checkmark. Whats wrong?

UPDATE:
Since no one has figure it out I will post most of my code to try and help figure it out. I have also reset my emulator to ensure there is not problems with corrupted data.

    chk1.setChecked(checker(1));
    chk2.setChecked(checker(2));
    chk3.setChecked(checker(3));
    chk4.setChecked(checker(4));
    }

    boolean checker(int value){
        DBAdapter db = new DBAdapter(this);
        boolean filled = false;
        db.open();
        for (int i = 1; i <= 4; i++) {
            String change = db.getMajorTitle(value).getString(1);
            if (change == null) {
                filled = false;
            }else{
                filled = true;
            }
        }
        db.close();
        return filled;
    }

If someone copies this and it works can you please tell me what might be wrong with my emulator or eclipse or whatever. Thanks everyone for there input.

FINISHED:
I noticed that at another part in my program I changed null to “”. I would like to thank everyone for being right and showing me different ways to code it.

Answer 1

You really don’t need if statements for this.

filled = (change != null);
