This tutorial will teach you how to make a MilkBar Inventory Management System using Java step by step. This system will helpful you to learn Inventory Management System.
Paste the Code inside the Add Button
double sum = 0;
if(chkst.isSelected())
{
String item = "strawberry";
double qty;
double cal;
double price;
qty = Double.parseDouble(txtSt.getText());
if(CboSt.getSelectedItem().equals("L"))
{
price = 200;
cal = price * qty;
}
else if(CboSt.getSelectedItem().equals("ML"))
{
price = 200;
cal = price * qty/1000;
}
else
{
price = 50;
cal = price * qty;
}
model = (DefaultTableModel)jTable1.getModel();
model.addRow(new Object[]
{
item,
qty,
price,
cal
}
);
}
if(chkcho.isSelected())
{
String item = "Cho";
double qty;
double cal;
double price;
qty = Double.parseDouble(txtCho.getText());
if(CboSt.getSelectedItem().equals("L"))
{
price = 100;
cal = price * qty;
}
else if(CboSt.getSelectedItem().equals("ML"))
{
price = 100;
cal = price * qty/1000;
}
else
{
price = 40;
cal = price * qty;
}
model = (DefaultTableModel)jTable1.getModel();
model.addRow(new Object[]
{
item,
qty,
price,
cal
}
);
}
if(chkven.isSelected())
{
String item = "Venila";
double qty;
double cal;
double price;
qty = Double.parseDouble(txtVal.getText());
if(CboSt.getSelectedItem().equals("L"))
{
price = 80;
cal = price * qty;
}
else if(CboSt.getSelectedItem().equals("ML"))
{
price = 80;
cal = price * qty/1000;
}
else
{
price = 30;
cal = price * qty;
}
model = (DefaultTableModel)jTable1.getModel();
model.addRow(new Object[]
{
item,
qty,
price,
cal
}
);
}
for(int i=0; i<jTable1.getRowCount(); i++)
{
sum = sum + Double.parseDouble(jTable1.getValueAt(i, 3).toString());
}
txtTot.setText(Double.toString(sum));
i have attached the video link below. which will do this tutorials step by step.
