Best performance for string to boolean conversion

Question

Which has best performance while converting String to boolean from the below options.

1. boolean value = new Boolean(\"true\").booleanValue();
<

Answer 1

boolean value = new Boolean("true").booleanValue();

Worst, creates new Boolean objects all the time. BTW booleanValue() is not necessary, unboxing will do it for you.

boolean value = Boolean.valueOf("true");

Much better, uses cached Boolean instance, but performs unnecessary (although very cheap) unboxing.

boolean value = Boolean.parseBoolean("true");

Best, nothing is wasted, operates barely on primitives, no memory allocations involved. BTW all of them delegate to (Sun/Oracle):

private static boolean toBoolean(String name) { 
  return ((name != null) && name.equalsIgnoreCase("true"));
}

If you are paranoid you can create your own toBoolean(String name) not ignoring case - negligibly faster:

boolean value = "true".equals(yourString);
