How to generate and display the execution plan

How to generate and display the execution plan:

========================================================

Option 1: Generating and displaying the execution plan for the last SQL statement executed in your session:

select * from MALLIK.STUDENT;

SET LINESIZE 150 

SET PAGESIZE 2000 

SELECT * FROM table (DBMS_XPLAN.DISPLAY_CURSOR); 

select plan_table_output from table(dbms_xplan.display_cursor(null,null,'basic'));

Option 2: Generating and displaying the execution plan from SQL_ID

SET LINESIZE 150 

SET PAGESIZE 2000 

SELECT * FROM table (DBMS_XPLAN.DISPLAY_CURSOR('atfg645km3ykp'));

SELECT * FROM table(dbms_xplan.display_cursor('fnrtqw9c233tt',null,'basic'));
