Frequently asked questions 
Take the certification for the language you use or want to be hired for. PCAP is an intermediate Python credential suited to junior developers, testers and data analysts. Java SE 21 Developer Professional (1Z0-830) is a harder, professional-level exam for Java developers and is valued in enterprise back-end roles.
PCAP (Certified Associate Python Programmer) validates intermediate Python: modules and packages, PIP, strings, generators, iterators and closures, file processing, exception handling, selected Standard Library modules and object-oriented programming. It sits between the entry-level PCEP and the professional PCPP1.
Passing 1Z0-830 earns the Oracle Certified Professional: Java SE 21 Developer credential. It covers object-oriented and functional programming, records, generics, Streams and Collections, concurrency, I/O, localization and Java modules.
