Hi Manoprabha,

If I am not wrong you want to first insert parent object record and then its child object record.

For this you need to first insert parent object record and after that create child object record and assign parent's id to child's lookup field.

Like as in case of Account and Contact we do

Account ac= new Account();
ac.Name='accountTest';
insert ac;
Contact con= new Contact();
con.lastName='lookupTest';
con.accountid=ac.id;
insert con;


here accountid is lookup field in contact which has lookup with account.​​​​​​​

Please mark it as Best Answer,if it helps.

Thanks
