{"Name", "Id","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"},
{"sandeep", "100","12.00pm to 1.00pm","","1.00pm to 2.00pm","","","",""},
{"amit", "101","","","1.00pm to 2.00pm","","12.00pm to 1.00pm","",""}
};
SQLiteDatabase studentDB=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try{
studentDB=openOrCreateDatabase("studentDB", Context.MODE_PRIVATE, null);
//for (int i = 0; i< 9 ; i++) {
String create="create table if not exists student1(dim2[0][0] varchar(20),dim2[0][1] varchar(20),dim2[0][2] varchar(20),dim2[0][3] varchar(30))";
studentDB.execSQL(create);
Toast.makeText(MainActivity.this, "Database created :", Toast.LENGTH_SHORT).show();
//}
}
catch(Exception e){
Toast.makeText(MainActivity.this, "Exception Occured:"+e.toString(), Toast.LENGTH_SHORT).show();
}

}
