    Default Array Sorting - Asc, Desc

    I am soritng an array in ascending and descending order. I am using the nethods in Arrays as below


    I want to print both input and output array in sysout.

    Object[] ipArray = [45,8,32,41,11,7];
    Object[] opArray;
    Object mArray = ipArray;

    Arrays.sort(mArray); This is changing the ipArray too ?

    How can I get my input array unmodified ?
