Read from the provided column index/name to last column : apache poi

Question

Here is the sample data. First row is header.

Demo1           Demo2           Demo3           Demo4           Demo5
DummyText1      DummyText2      DummyText3      DummyText4      DummyText5
DummyText11     DummyText21     DummyText31     DummyText41     DummyText51

I want to read data after the provided column index/name till last column. However with the below code specified column index get skipped.

for (Row row : xssfSheet4) {
    if (row.getRowNum() == 0) {
        continue;
    }
    //
    for (Cell cell1 : row) {
        if (cell1.getColumnIndex() == 1) {
          continue;
        }
        //
    }
}

With the above code, Demo2 column skipped and read as

Demo1           Demo3           Demo4           Demo5
DummyText1      DummyText3      DummyText4      DummyText5
DummyText11     DummyText31     DummyText41     DummyText51 

However, it should read as

Demo3           Demo4           Demo5
DummyText3      DummyText4      DummyText5
DummyText31     DummyText41     DummyText51
