The document contains programming assignments for multiple days including: 1) A program to display the multiplication table for a user-entered number. 2) A menu-driven program to calculate the cube, square root, and exponential of a user-entered number. 3) A program to check if a string starts with the contents of another string. 4) A program to remove duplicate elements from an array and return the new length. It also provides a link to a Hackerrank challenge on Java strings introduction.
