Practical No - 8

This document contains two Java programs that create JTables. The first program creates a JTable to display employee data including ID, name, and salary. It adds the JTable to a JScrollPane and adds that to a JFrame. The second program creates a JTable to display student data including name, percentage, and grade for 10 students. It also adds the JTable to a JScrollPane and adds that to a JApplet. Both programs demonstrate how to populate and display data in a JTable.
