It is like the Vector in C. Since Java does not have the concept of methods as first-class entities this is only possible using reflection which is painful and error-prone.
Call the fullThrottle method myCarspeed200. In addition to implementing the List interface this class provides methods to manipulate the size of the array that is used internally to store the list. HashCodechar myArray Hash code of the character array.

Q 2 Which sorting is used in arrays sort in Java. SystemoutprintlnHashCode for short array. We will discuss each method individually later in this tutorial.
In was given in Java 18 version. Native Method or the Brute force method Using ArraysasList Method Using CollectionsaddAll Method Using Java 8 Stream API Using Guava ListsnewArrayList Method. In the following example we are passing an array of short values to the hashCode method and this method returns a hash code based on the content of the array in the integer format.
Arrays are used to store multiple values in a single variable instead of declaring separate variables for each value. B start_index-the index from where the sorting should be started. Create a myCar object myCarfullThrottle.
It also contains various methods to manipulate the arrays like sorting searching representing arrays as strings etc.
