Study guide
In this lab you write Java programs on I/O and arithmetic, expressions, volumes, tables, primes, Fibonacci, factorial, quadratics, weekdays, Pascal's triangle, arrays and matrices, string analysis, inheritance types, access specifiers, interfaces, packages, exception handling, threads and further programs. Run each with edge-case inputs.
Why Java Technologies Laboratory Matters
These are the standard programs in placement coding rounds and form the base for larger Java projects.
How to Prepare for Java Technologies Laboratory
- Write each program yourself and test it.
- Use an IDE and its debugger.
- Prepare to explain logic in the viva.
