As seen from above the Reference queue actually holds within it the WeakReference which lost its heap object to clean up. The WeakReference does not have any association to the memory object. The get call above returns null.Unlike with finalize when we can make the object alive again, with t...
String anotherString = (String)anObject; int n = value.length; if (n == anotherString.value.length) { char v1[] = value; char v2[] = anotherString.value; int i = 0; while (n-- != 0) { if (v1[i] != v2[i]) return false; i++; } return true; } } return false; }...
not the real value. Primitive types are allocated in the stack memory, so only the local value will be changed. In this case, there is no object reference.
As stated in The KeyStore Class, there are two different types of entries in a keystore. The following methods determine whether the entry specified by the given alias is a key/certificate or a trusted certificate entry, respectively:final boolean isKeyEntry(String alias) final boolean is...
