AtomicLongArrayaccumulateAndGet() method in Java, example
AtomicLongArray accumulateAndGet() method in Java, examples Original text: https://www . geeksforgeeks . org/atomicongarray-accumulatedget-method-in-Java-with-examples/ Java . util . concurrent . atomic . atomicongarray . accumulate dget() is a built-in method in Java that works by applying a given function to the current value and the given value. The result of the fixed value automatically updates the element at index I and returns the updated value. This function should have no side effects, as it may be reapplied when an attempted update fails due to contention between threads. The first parameter of this function is the current value at index I and the second parameter is the given update. Syntax: Public final long cumulative number (int i, long x, LongBinaryOperator cumulative function) Parameters:This function accepts three parameters: I – The updated index is the motor. x–The value that is calculated using the value of i accumulatorFunction – A side-effect-free function of two arguments . Return value: This function returns the updated value, which is within long.

Java string trim() method, example
Java string trim() method, example Original text: https://www . geesforgeks . org/Java-string-trim-method-example/ The trim() method in Java String is a built-in function that removes leading and trailing spaces. The Unicode value of the space character is “\u0020”. The trim() method in java checks the Unicode values before and after the string, if present, removes the spaces and returns the omitted string. The trim() method also helps in trimming characters in Java. Note:The trim() method does not eliminate intermediate spaces. Method signature: public String trim() Parameters:The trim() method does not accept any parameters. Return type: The return type of the trim() method is Chord. It returns the omitted string without leading and trailing spaces. Here is a working example of the trim() method for displaying strings in Java.
