This is going to be an easy one. As of Java 17, this keyword is obsolete. Prior to Java 17, this keyword was used to establish a strict floating-point (strict fp) policy. This meant that, when in use, this keyword guaranteed that floating point calculations would yield the same result across all hardware. When not in use, the Operating System had some leeway in refining precision of floating-point calculations. The keyword would be applied at

The assert keyword enables you to test an assumption about a part of your program. If the assertion is proven to be true, execution of your program will continue. If it's proven to be false, an AssertionError will be thrown. Assertions confirm your assumptions about the behavior of your program, thus increasing confidence that the program is free of errors. This keyword has been part of the Java language since Java 1.4.2 and yet, very l

This article summarize the use of the keyword static . I suggest you review Java Keywords (Part V): Classes vs Interfaces and Java Keywords (Part IX): Switch Statements before proceeding.

Very early in this series, I discussed the use of the keyword static and mentioned that I would leave for later discussion another use of that keyword. Well, the time has come. Using static method in interfaces Let me start by saying that the only re

Up until Java 8 (released in March, 2014), the default keyword had a single purpose, which was to indicate the default case in a switch statement. To illustrate quickly String color = "red"; switch(color) { case "red": case
