    Default please help to solve number display in E7

    Hi, please help.
    i'm having problem in my code, that a number display in E7 example 10.000.000 it display as 1E7.

    here is my code:

    private void GridListing() {
    try {
    statement = DBConnections.getDBConnectionSys().createStatement ();
    if (jSearchBy1.getSelectedItem() == "Kode Jurnal")
    Criteria = " WHERE journal_no Like '" + jTxtSearch1.getText() + "%'";
    else if (jSearchBy1.getSelectedItem() == "Tanggal Jurnal")
    Criteria = " WHERE journal_date '" + jTxtSearch1.getText() + "%'";
    //Different DB Different Terms of Syntax
    if (GlobalSettings.dataBaseType == 1 || GlobalSettings.dataBaseType == 2) {
    Query = ("SELECT TOP 100 * FROM " + Table + Criteria); }
    if (GlobalSettings.dataBaseType == 3 || GlobalSettings.dataBaseType == 4) {
    Query = ("SELECT * FROM " + Table + Criteria );
    }
    result = statement.executeQuery(Query);

    int Numrow = 0;
    int Numrow1 = 0;
    int MaxProgress = 100;
    //
    ResultSet rs= statement.getResultSet();
    ResultSetMetaData md = rs.getMetaData();
    int columnCount = md.getColumnCount();
    Vector data = new Vector(columnCount);
    Vector row = new Vector(columnCount);
    Vector columnNames = new Vector(columnCount);
    for (int i = 1; i <= columnCount; i++) {
    columnNames.addElement( md.getColumnName(i));
    }
    while (rs.next()) {
    for (int i = 1; i <= columnCount; i++) {
    row.addElement(rs.getObject(i));
    }
    data.addElement(row);
    row = new Vector(columnCount); // Create a new row Vector
    Numrow++;

    }

    DefaultTableModel model = new DefaultTableModel(data, columnNames);
    jTable1.setModel( model );
    jTable1.setSelectionMode(ListSelectionModel.SINGLE _SELECTION);
    jTable1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    jTable1.setDefaultEditor(Object.class, null);
    String header[] = {"Kode Jurnal"};
    for(int i=0;i<jTable1.getColumnCount();i++)
    {
    TableColumn column1 = jTable1.getTableHeader().getColumnModel().getColum n(i);
    column1.setHeaderValue(header[i]);
    column1.setPreferredWidth(100);
    }
    } catch (SQLException sqlex) {
    jLblStatementError.setText(sqlex.toString());
    }
    }

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    display in E7 example 10.000.000 it display as 1E7.
    How are you formatting the number for display? Have you tried the printf() method or the methods of the DecimalFormat class?
    If you don't understand my answer, don't ignore it, ask a question.

    If you want to get a String from a number, use the DecimalFormat class method to do the conversion.

    Hi Norm, I knew that function but how to apply to my code below?
    int Numrow = 0;
    int Numrow1 = 0;
    int MaxProgress = 100;
    //
    ResultSet rs= statement.getResultSet();
    ResultSetMetaData md = rs.getMetaData();
    int columnCount = md.getColumnCount();
    Vector data = new Vector(columnCount);
    Vector row = new Vector(columnCount);
    Vector columnNames = new Vector(columnCount);
    for (int i = 1; i <= columnCount; i++) {
    columnNames.addElement( md.getColumnName(i));
    }
    while (rs.next()) {
    for (int i = 1; i <= columnCount; i++) {
    row.addElement(rs.getObject(i));
    }
    data.addElement(row); ----> this data display here. but how to apply decimal class funcion????
    row = new Vector(columnCount); // Create a new row Vector

    What variable has the numeric value you want to format?
    Where is that variable's value converted to a String to be displayed?


    Note: The code in post#7 has lost all its indentations making it harder to read and understand. Please try to preserve code's formatting when posting it.

    at the column index of 8 should be numeric, the rest are string.

    Much better formatting for the posted code.

    column index of 8 should be numeric, the rest are string.
    Can you make them all String and apply formatting to column 8 to display the numbers as desired?
