In their own words
Javadoc
Javadoc creates HTML API documentation from Java source files and is installed with the Java Development Kit (JDK). Its standard doclet describes public and protected Java types and members, including classes, interfaces, constructors, methods, and fields. It can process packages, individual source files, or both, with an option to include subpackages recursively. Alternate doclets can change the content and format of the generated output, while taglets add support for custom tags in documentation comments. The standard doclet includes DocLint to help identify common comment problems, but DocLint does not check conformance or repair errors. Oracle cautions that generated output may pose issues if it is non-conformant or contains executable content such as JavaScript. JDK 25 downloads are listed for Linux, macOS, and Windows. JDK 25 binaries are free under Oracle No-Fee Terms and Conditions through September 2028; later updates use a license that may require fees for production use beyond limited free grants.
YourKit Java Profiler
YourKit Java Profiler analyzes Java applications and servers locally or remotely in development, testing and production. CPU results can be viewed as call trees or hotspot lists, and a what-if feature estimates optimization gains without another profiling run. Memory views map the heap and object graph, including the memory retained by each object. More than 40 inspections flag issues such as leaked webapps, duplicated objects, unclosed SQL statements, inefficient collections and I/O operations. The profiler also identifies slow SQL queries and HTTP requests and supports databases including MongoDB, Cassandra and HBase. Plugins for Eclipse, IntelliJ IDEA and NetBeans link profiling results to source code. Remote profiling needs SSH access, while UI-to-agent communication uses SSL-encrypted TCP/IP. Downloads are available for Linux, macOS and Windows; APIs, command-line tools and export formats support automation. A free plan and a paid model are listed, and an evaluation license can be requested for up to 15 days. The pricing note gives a starting price of $99/user/yr.
