$java EnumConstantsEnum name: Eon Enum constants: [HADEAN, ARCHAEAN, PROTEROZOIC, PHANEROZOIC] Eon.values(): [HADEAN, ARCHAEAN, PROTEROZOIC, PHANEROZOIC] Since enums are classes, other information may be obtained using the same Reflection APIs described in theFields,Methods, andConstructorssection...
In Java, you create an enumerated data type in a statement that uses the keyword enum, an identifier for the type, and a pair of curly braces that contain a list of the enum constants, which are the allowed values for the type. For example, the following code creates an enumerated type...
Otherwise, one array is a proper prefix of the other and, lexicographic comparison is the result of comparing the two range lengths. (See #mismatch(int[], int, int, int[], int, int) for the definition of a common and proper prefix.) Added in 9. Java documentation for java.util....
You can use the elements in a Java array just like if they were ordinary variables. You can read their value, assign values to them, use the elements in calculations and pass specific elements as parameters to method calls. The indexes of elements in a Java array always start with 0 and ...
One way to create an array is with thenewoperator. The next statement in theArrayDemoprogram allocates an array with enough memory for 10 integer elements and assigns the array to theanArrayvariable. // create an array of integers anArray = new int[10]; ...

Another way of concatenating two arrays in Java is by using the System.arraycopy() method (works for both primitive and generic types), as shown below: int[] arr1 = {1, 2, 3, 4}; int[] arr2 = {5, 6, 7, 8}; // create a new array int[] result = new int[arr1.length ...
