Gracefully avoiding NullPointerException in Java

Question

Consider this line:

if (object.getAttribute(\"someAttr\").equals(\"true\")) { // ....

Obviously this line is a potential bug, the attribute

Answer 1

It's a very good question. I usually use the not graceful:

if (object.getAttribute("someAttr") != null && object.getAttribute("someAttr").equals("true")) { // ....

(and I will not use it anymore)
