Arrays package in java

how to import arrays package in java and what are the methods available in this Arrays class

Java provides a built-in class called java.util.Arrays that provides various utility methods for manipulating arrays. These methods can be used to perform common operations on arrays such as sorting, searching, and filling.

Here are some of the commonly used methods in the java.util.Arrays package:

1. sort(): This method is used to sort the elements of an array in ascending order. There are overloaded versions of this method that can be used to sort arrays of different types.
2. binarySearch(): This method is used to search for a specific element in a sorted array. It returns the index of the element if found, or a negative value if the element is not present in the array.
3. equals(): This method is used to compare two arrays for equality. It returns true if the two arrays contain the same elements in the same order, and false otherwise.
4. fill(): This method is used to fill an array with a specific value. It takes an array and a value as arguments and sets all the elements of the array to the specified value.
5. copyOf(): This method is used to create a copy of an array. It takes an array and a length as arguments and returns a new array with the specified length containing the elements of the original array.
6. toString(): This method is used to convert an array to a string. It returns a string representation of the array, with the elements separated by commas and enclosed in square brackets.

These are just a few examples of the methods provided by the java.util.Arrays package. There are many other methods in this package that can be used to manipulate arrays.
