// printing the array data1
System.out.println("before copy new array:");
for (int k = 0; k < data.length; k++)
{
System.out.println(data[k]);
}
String[] data2 = Arrays.copyOf(data, 4);
// printing the array data2
System.out.println("after copy new array:");
for (int k = 0; k < data2.length; k++)
{
System.out.println(data2[k]);
}}}
