This Practical assignment lab manual is designed keeping in mind strictly the Internal Assessment of Computer Applications for ICSE class IX. It has the resources to cover Internal Assessment with twenty five programs covering each and every topic and aspect of the syllabus as given by the ICSE. IF the teacher want to give some weightage to the class work he/she can do so, otherwise full hundred marks could be assigned for this file. The solution to the programs are done on BlueJ 3.2 with a compatibility with JDK 5.0 and prescribed by the council. There is space for all the practical work, Output and VDV as asked by the Council and as required to be done for Internal Assessment. The council requires a minimum of twenty programs to be done in the Internal Assessment file. But we have given Twenty Five Programs from each topic making it easy for the teacher to select the best for their students. There is extra space also available for some extra programs.
