Java offers a static ArrayCopy method from System class: java.lang.System.arraycopy() method offers a convenient method to copy array elements from one array to another. System.arraycopy(Object source_array, int source_position, Object destination_array, int destination_position, number_of_elements) System.arraycopy() takes five parameters. First parameter specifies the source_array from where the elements need to be copied. Second parameter is the position(index) value of the source array ...

When we say static it is static throughout the application. If you declare ...
