Introduction
The java.lang.reflect.Array class provides static methods to dynamically create and access Java arrays. Array permits widening conversions to occur during a get or set operation, but throws an IllegalArgumentException if a narrowing conversion would occur.
Class declaration
Following is the declaration for java.lang.reflect.Array class −
public final class Array extends Object
Class methods
| Sr.No. | Method & Description |
