If the total memory usage of the array is not a multiple of 8 bytes, then the size is rounded up to the next mutlitple of 8 (just as for any other object). Note that a boolean array requires one byte per element, even though each element actually only stores a single bit of ...

The maximum size of a String is limited by the maximum size of an array, which is Integer.MAX_VALUE. According to the Java specification, the maximum value of Integer.MAX_VALUE is always 2147483647, which represents2^31 - 1. The size of a String is determined by the number of characters...
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....
