Dictionary is an abstract class that represents a key/value storage repository and operates much like Map. Given a key and value, you can store the value in a Dictionary object. Once the value is stored, you can retrieve it by using its key. Thus, like a map, a dictionary can ... Read More

The toArray() method of the Ints class returns an array containing each value of collection, converted to a int value in the manner of Number.intValue(). Following is the syntax −public static int[]    toArray(Collection

The max() method of the Ints class returns the greatest value present in array. Following is the syntax −static int max(int... array)Let us first see an example −Exampleimport com.google.common.primitives.Ints; class Demo {    public static void main(String[] args) {       int[] myArr = { 10, 20, 30, 40, ...

The lastIndexOf() method of the Ints class returns the index of the last appearance of the value target in array. The syntax is as follows −public static int lastIndexOf(int[] arr, int target)Here, arr is the array of int values, whereas target is the int value for which we are finding ... Read More
