Nullpointer exception when writing a file to the desktop, but its not the file path

Question

This is my write function

void writeText(Text[] t) {
    try {
        writer = new PrintWriter(new FileWriter(FILE_PATHPhrase));
        // Loop through each Person in the Person array
        for (int i = 0; i < t.length; i++) {
            // Write the name, then a # sign, then the surname
            writer.println(t[i].getTitle() + "#" + t[i].getText());

        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    writer.close();
}

The nullpointer points here

 writer.println(t[i].getTitle() + "#" + t[i].getText());

I have no clue on why it does this..

might be `t[i]` is null. add null check condition before accesing it. — bNd, Jan 28 '16 at 07:07
Where are you calling `writeText()`? Just check whether the `Text[]` created or not. — SatyaTNV, Jan 28 '16 at 07:12

Try with null check. You have to check why its coming null. for safe side you can check it before accessing.

 for (int i = 0; i < t.length; i++) {
            // Write the name, then a # sign, then the surname
            if(t[i]!=null){
            writer.println(t[i].getTitle() + "#" + t[i].getText());
}
}
