String equals not working correctly

This is my debugging code:

log.error(u.getName() + " - " + u.getName().length() + " - host_node" + " - " + u.equals("host_node"));

My log:

11:27:16 [main] ERROR com.google - host_node - 9 - host_node - false

Why it doesn't equal, I am even checking length, to see if first contains whitespaces. But it does not.

Solution

  • I would use following as I suspect u is not a String.

    u.getName().equals("host_node")

    or better you can use the following to get false if the name is null.

    "host_node".equals(u.getName())
