AtomicLongArraygetAndAccumulate() method in Java, example
AtomicLongArray getAndAccumulate() method in Java, examples Original text: https://www . geeksforgeeks . org/atomicongarray-getandaccumulate-method-in-Java-with-examples/ Java . util . concurrent . atomic . AtomicLongArray . getandaccumulate() is a built-in method in Java that applies the given function to the current value and the given value, automatically updates the value at any index of the atomicongarray with the result, returning the previous value. This method accepts as parameters the index of the atomic clone array to perform the operation on, the value to perform the operation on, and the accumulator function. This function is applied with the current value at index as its first argument and the given update as its second argument. The accumulator function should have no side effects because it can be reapplied when an attempted update fails due to contention between threads. The function getAndAccumulate() is similar to accumulated gt(), but the former returns a value before updating and the latter returns a value after updating. Syntax: Public final long getAndAccumulate(int i, long x, LongBinaryOperator accumulator function) Parameters:This function accepts three parameters: I – the index to be updated. x–The value to operate on with the value at I accumulatorFunction – A side-effect-free function of two arguments.

KeyStore isCertificateEntry() method in Java, examples Original text: https://www . geesforgeks . org/keystore-iscertifientry-method-in-Java-with-examples/ The isCertificateEntry() method of the java.security.KeyStore class is used to check whether the specified certificate entry exists in this KeyStore instance. It returns a boolean value representing the same. Syntax: public final boolean isCertificateEntry(String alias) throws KeyStoreException Parameters:This method accepts alias The name of the parameter whose certificate entry is to be checked. Return Value: This method checks whether the certificate entry for the requested alias exists and returns a Boolean value. Exception: If the keystore has not been initialized, this method throws KeystoreException. Note: None of the programs in this article will run on the online IDE because the “privatekey” keystore does not exist. You can inspect this code on your system’s Java compiler.
