To test the Triangle t and t.calculateArea(), we need to create an extra if condition. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the Java TM platform. Java 17 restores the pre-Java 1.2 strict floating-point calculations as default, which means the keyword strictfp is now optional.Ĭase null -> ("Unknown!") Ĭase "Java 11", "Java 17" -> ("LTS") The JDK is a development environment for building applications using the Java programming language.Now, since Intel and AMD have both support SSE2 (Streaming SIMD Extensions 2) extensions, which could support for the strict JVM floating-point operations without the overheats, so, the previous (before Java 1.2) overheats issues on x87-based hardware are irreverent in nowaday hardware.The default floating-point calculation was changed from strict to subtly different floating-point calculations (avoid overheats issues). Since Java 1.2, we need the keyword strictfp to enable the strict floating-point calculation.Before Java 1.2, all floating-point calculations were strict and it caused overheats on x87-based hardware.
This JEP is for numerically-sensitive programs, mainly scientific purposes It again made default floating-point operations strict or Strictfp, ensure the same results from the floating-point calculations on every platform. JEP 306: Restore Always-Strict Floating-Point Semantics Pseudorandom number generator, pattern matching for switch (preview), sealed class (standard feature), foreign function & memory API (incubator), dynamic deserialization filters. JEP 415: Context-Specific Deserialization Filters JEP 412: Foreign Function & Memory API (Incubator) JEP 411: Deprecate the Security Manager for Removal JEP 410: Remove the Experimental AOT and JIT Compiler JEP 406: Pattern Matching for switch (Preview)
JEP 403: Strongly Encapsulate JDK Internals JEP 398: Deprecate the Applet API for Removal JEP 356: Enhanced Pseudo-Random Number Generators
