Java code review
Each new version of IntelliJ IDEA will expand its static code analysis capabilities, and this version is of course no exception. In addition to a series of improvements, 2020.1 also added new code inspection capabilities.

Data flow analysis assistance function
IntelliJ IDEA 2020.1 adds a dataflow analysis assistance function to the debugger. This function predicts and displays possible exceptions and always true / false conditions based on the current state of program execution.
When we debug Java code and reach a breakpoint, the IDE will run a data flow analysis based on the current state of the program and show us what will happen next before the code reaches this breakpoint:
