New to Java

Have some queries regarding on two dimensional array.

For example :

                         Object[][] objectArray = new Object[][]{{ 1.0D,2.0D,3.0D},{ 4.0D,5.0D,6.0D},{ 7.0D,8.0D,9.0D}};

                         Object[][] copyObjectArray = Arrays.stream(objectArray).map(x -> x.clone()).limit(2).toArray(Object[][]::new);

                         System.out.println(Arrays.deepToString(copyObjectArray));

     The above snippet returns the output like [[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]] because it's limit two rows.

     Is there any function two remove column or limit the column using Java 8 lamda function ?.

     Awaiting for your response.
