int i=0; int u=0,f=0;
String choice, again; char c,ans;
do{ choice = JOptionPane.showInputDialog(" MENU " + "\n" + "[a] ADD a RECORD " + "\n" + "[d] DISPLAY RECORDs" +"\n" + "[e] DELETE a RECORD"+"\n" + "[p] UPDATE a RECORD"+"\n" + "[s] SEARCH a RECORD"+"\n" + "Enter choice: ");

switch(c){ case 'a': student = new Student(); name=JOptionPane.showInputDialog(" Enter name: "); student.setName(name);
String mg = JOptionPane.showInputDialog("Name: "+name + "\nEnter Math Grade "); m = Double.parseDouble(mg); student.setmGrade(m); String eg = JOptionPane.showInputDialog("Name: "+name + "\nEnter English Grade "); e = Double.parseDouble(eg); student.seteGrade(e); String sg = JOptionPane.showInputDialog("Name: "+name + "\nEnter Science Grade "); s = Double.parseDouble(sg); student.setsGrade(s);
i++;
break;
case 'd': if (i==0) JOptionPane.showMessageDialog(null,"NO RECORDS yet!!!");
up = JOptionPane.showInputDialog("Enter name to search: "); for(int x=0; x<i; x++){ if ((student[x].getName().equalsIgnoreCase(up))){ u=x; f=1; JOptionPane.showMessageDialog(null,"FILE FOUND!!!"); break; } }
