Is there an equivalent to memcpy() in Java?

by

Use System.arraycopy()

System.arraycopy(sourceArray, 
                 sourceStartIndex,
                 targetArray,
                 targetStartIndex,
                 length);

Example,

String[] source = { "alpha", "beta", "gamma" };
String[] target = new String[source.length];
System.arraycopy(source, 0, target, 0, source.length);

or use Arrays.copyOf()

Example,

target = Arrays.copyOf(source, length);

java.util.Arrays.copyOf(byte[] source, int length) was added in JDK 1.6.

The copyOf() method uses System.arrayCopy() to make a copy of the array, but is more flexible than clone() since you can make copies of parts of an array.
