I have a JTable
with the column names " Names "
, " Quantity "
and " Unit "
. I'm coding a program where you get the ingredients names. So i need to get the whole row of one column and String it all up together, because i need to store it in mySql and i have already set it all as String. Any idea how i can do this ? My code are as follows :
JTable Code:
DefaultTableModel model = (DefaultTableModel)table.getModel();
if(!txtQty.getText().trim().equals("")){
model.addRow(new Object[]{ingCB.getSelectedItem().toString(),txtQty.getText(),unitCB.getSelectedItem().toString()});
}else{
JOptionPane.showMessageDialog(null,"*Quantity field left blank");
}
Getting the values and for storing :
for(int i = 1; i<= i ; i++){
ingredients = table.getName();
}
This is for loop is wrong and it does not work because i have a constructor to take in Ingredients but because it is inside the loop, it cannot take it in. Any suggestions please ? Thank you.
Constructor :
Food e2 = new Food(Name, Description, priceDbl, Image, Category, Ingredients, promotion );
e2.createFood();

Want to do so, try this. Here I am getting result into ArrayList
and String
, as I am commented ArrayList
you can avoid it.
public class TableValuePrint extends JFrame implements ActionListener{
private final JButton print;
private final JTable table;
private String str="";
public TableValuePrint() {
setSize(600, 300);
String[] columnNames = {"A", "B", "C"};
Object[][] data = {
{"Moni", "adsad", "Pass"},
{"Jhon", "ewrewr", "Fail"},
{"Max", "zxczxc", "Pass"}
};
table = new JTable(data, columnNames);
JScrollPane tableSP = new JScrollPane(table);
JPanel tablePanel = new JPanel();
tablePanel.add(tableSP);
tablePanel.setBackground(Color.red);
add(tablePanel);
setTitle("Result");
setSize(1000,700);
print=new JButton("Print");
JPanel jpi1 = new JPanel();
jpi1.add(print);
tablePanel.add(jpi1,BorderLayout.SOUTH);
print.addActionListener(this);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
TableValuePrint ex = new TableValuePrint();
ex.setVisible(true);
}
});
}
@Override
public void actionPerformed(ActionEvent ae) {
if(ae.getSource()==print){
// ArrayList list = new ArrayList();
for(int i = 0;i<table.getModel().getRowCount();i++)
{
//list.add(table.getModel().getValueAt(i, 0)); //get the all row values at column index 1
str=str+table.getModel().getValueAt(i,0).toString();
}
//System.out.println("List="+list);
System.out.println("String="+str);
}
}
}
Output
String=MoniJhonMax
