In Java, there’s an alternative method for initializing arrays that doesn’t involve explicitly using thenewkeyword. Instead, you can directly assign values to the array. Let’s explore this approach through the following example: importjava.util.Arrays;publicclassDeclareEmptyArray{publicstaticvoidma...
To convert an array to a Set in Java, you can use the Arrays.asList() method to create a List from the array, and then use the List.toSet() method to create a Set from the List. Here is an example of how to convert an array to a Set: import java.util.Arrays; import java....
