Column result doesn't as be expected

Question

Here i have query to join two table and merge it into one result by using this query

String query = "SELECT * FROM tb_barang RIGHT JOIN tb_jenis ON tb_barang.kd_jenis = tb_jenis.kd_jenis ";

And here is my table structures for both of tables

Table "tb_barang"

And Table "tb_jenis"
https://i.sstatic.net/UhLty.png

I was expecting the output like this

However, when I take column "jenis", java throw exception into it because either out of range or column not found.

Then i check whether the column is exist or not using :

ResultSet resTabel = new mysqlDriver().getKolomBarangList();
            ResultSetMetaData metaData = resTabel.getMetaData();
            int colCount = metaData.getColumnCount();
            if (resTabel.next()) {
        for (int i = 1; i <= colCount; i++) {
        System.out.println("Col(" + i + ") '" + metaData.getColumnName(i) + "' value:" + resTabel.getString(i));
    }

The output:

Col(1) 'kd_barang' value:BAR0000
Col(2) 'nama_barang' value:A
Col(3) 'kd_jenis' value:J_1
Col(4) 'jumlah_barang' value:1
Col(5) 'harga_satuan' value:1
BUILD SUCCESSFUL (total time: 35 seconds)

How to achieve this? Thanks for response

Answer 1

Apparently, i was miss type the method name thanks to @forpas. the getKolomBarangList() refer to field name of table tb_barang and not executing "JOIN" clauses

protected ResultSet getBarangList()throws SQLException, NullPointerException, ClassNotFoundException{
        String query = "SELECT * FROM tb_barang RIGHT JOIN tb_jenis ON tb_barang.kd_jenis = tb_jenis.kd_jenis ";
        if(resForListBarang == null){
            resForListBarang = alwaysDoResultSet(query);
        }
        return resForListBarang;
    }

    protected ResultSet getKolomBarangList() throws SQLException, Exception{
        String query = "SELECT * FROM tb_barang";
        if(getBarangKolom == null){
            getBarangKolom = alwaysDoResultSet(query);
        }
        return getBarangKolom;
    }

And the output for getBarangList() was expected as the final result

Col(1) 'kd_barang' value:BAR0000
Col(2) 'nama_barang' value:A
Col(3) 'kd_jenis' value:J_1
Col(4) 'jumlah_barang' value:1
Col(5) 'harga_satuan' value:1
Col(6) 'kd_jenis' value:J_1
Col(7) 'jenis' value:Pakan Hewan

Thanks to anyone who helping me out :)
