Java Cloning of Multidimensional ArraysThe following, example program (CloneTwoDArrayDemo.java) demonstrates how clone method works on array of arrays in Java, and what are its side effects? Following program demonstrates the inability of Java cloning that creates a duplicate copy of two dimensional...
In this example the Output starts with a buffer that has a capacity of 1024 bytes. If more bytes are written to the Output, the buffer will grow in size without limit. The Output does not need to be closed because it has not been given an OutputStream. The Input reads directly from ...
