Notice.. you could also write it like that

 public static Integer convertToInt(String str) {
    int n=0;
    if(str != null && str.length()>0) {
        n = Integer.parseInt(str);
    }
    return n;
}

but the try/catch method is way more effective and simple and will not cause a system exit if a letter get inside the String (just worth mentioning)

also, it is important to notice that writing the same equation like that:

if(str != null & str.length()>0) {}

or like that:

if(str.length()>0 && str != null) {}

can cause the operation to fail because it will try to count the String even if it is null

Hope I responded to all your questions
