### Question:
Arrays2D { public static short[][] combine(short[][][][] wrapper) throws InputMismatchException { return combine(wrapper, 0, false); }  static float[][] copyOfRange(float[][] input, int topleft, int bottomright); static float[][] copyOfRange(float[][] input,
            int top, int right, int bottom, int left); static short[][] combine(short[][][][] wrapper); static short[][] combine(short[][][][] wrapper, int width, int height); static short[][] combine(short[][][][] wrapper, int overlap, boolean validate); static short[][] combine(short[][][][] wrapper, int width, int height,
            int overlap, boolean validate);  }### Answer:
@Test public void testCombineShortArrayArrayArrayArrayIntBoolean() { short[][] actual = Arrays2D.combine(wrap, 1, true); assertArray2dEquals(exp, actual); }
@Test public void testCombineShortArrayArrayArrayArrayIntIntIntBoolean() { try { short[][] actual = Arrays2D.combine(wrap, 5, 5, 1, true); assertArray2dEquals(exp, actual); } catch(Exception e) { fail(e.getMessage()); } }
@Test public void testCombineShortArrayArrayArrayArrayIntIntIntBoolean2() { try { short[][] actual = Arrays2D.combine(wrapFail, 5, 5, 1, true); fail("Should have thrown InputMismatchException!"); } catch(InputMismatchException e) { } }
