now this is my code for Crud operation of CompanyDetail
public class CompanyCrud {
private DBHelper dbHelper;
public CompanyCrud(Context context) { dbHelper = new DBHelper(context);}
public int insert(Company company){
SQLiteDatabase db = dbHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(Company.KEY_cname, company.cname);
values.put(Company.KEY_cstanding, company.cstanding);
values.put(Company.KEY_crepres, company.crepres);
values.put(Company.KEY_ccontact, company.ccontact);
values.put(Company.KEY_cemail, company.cemail);
long company_Id = db.insert(Company.TABLE, null, values);
db.close();
return (int) company_Id;
}
public void delete(int company_Id) {
SQLiteDatabase db = dbHelper.getWritableDatabase();
db.delete(Company.TABLE,Company.KEY_ID + "=?", new String[]{ String.valueOf(company_Id) });
db.close();
}
public void update(Company company) {
SQLiteDatabase db = dbHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(Company.KEY_cname, company.cname);
values.put(Company.KEY_cstanding, company.cstanding);
values.put(Company.KEY_crepres, company.crepres);
values.put(Company.KEY_ccontact, company.ccontact);
values.put(Company.KEY_cemail, company.cemail);
db.update(Company.TABLE, values, Company.KEY_ID + "= ?", new String[]{String.valueOf(company.company_ID)});
db.close();
}
public ArrayList<HashMap<String, String>> getCompanytList () {
SQLiteDatabase db = dbHelper.getReadableDatabase();
String selectQuery = "SELECT " +
Company.KEY_ID + "," +
Company.KEY_cname + "," +
Company.KEY_crepres + "," +

Company.KEY_cemail +
" FROM " + Company.TABLE;
ArrayList<HashMap<String, String>>companyList = new ArrayList<HashMap<String, String>>();
Cursor cursor= db.rawQuery(selectQuery, null);
if (cursor.moveToFirst()){
do{
HashMap<String , String > company = new HashMap<String, String >();
company.put("cid", cursor.getString(cursor.getColumnIndex(Company.KEY_ID)));
company.put("cname", cursor.getString(cursor.getColumnIndex(Company.KEY_cname)));
companyList.add(company);
} while (cursor.moveToNext());
}cursor.close();
db.close();
return companyList;
}
public Company getCompanyById(int cid) {
SQLiteDatabase db = dbHelper.getReadableDatabase();
String selectQuery = "SELECT " +
Company.KEY_ID + "," +
Company.KEY_cname + "," +
Company.KEY_crepres + "," +

int ictrc =0;
Company company = new Company();
Cursor cursor = db.rawQuery(selectQuery, new String[]{ String.valueOf(cid)});
if (cursor.moveToFirst()){
do {
company.company_ID=cursor.getInt(cursor.getColumnIndex(Company.KEY_ID));
company.cstanding=cursor.getString(cursor.getColumnIndex(Company.KEY_cstanding));
company.crepres=cursor.getString(cursor.getColumnIndex(Company.KEY_crepres));
company.ccontact= cursor.getString(cursor.getColumnIndex(Company.KEY_ccontact));
