Java keyword list abstract continue for new switch assert default goto * package synchronized boolean do if private this break double implements protected throw byte else import public throws case enum instanceof return transient catch extends int short try char final interface static void class finally long strictfp volatile const * float native super while Keyword marked with an asterisk (*) are keywords that, although valid, are not used by programmers. This is the last chapter of the Java Keyword series. This is probably the keyword I have used the least. In my 20 year career as a software developer, I have used this keyword once, and that was to make some addition to legacy code. The keyword native is a method modifier . Basically, it is a keyword that can only be applied to methods. According to the Java Language Specification (JLS), A method that is native is implemented i...
Since originally my Java series was based on Java 8, it did not include a new keyword introduced later on. For that reason, I decided to post an addition to the Java Keyword series to include the Java record keyword. Introduced in Java 14, the purpose of this keyword is to eliminate all the boilerplate code when creating a Java POJO. For example, public class Student { private String name; private int id; public Student(String name, int id) { this.name = name; this.id = id; } public String getName() { return name; } public int getId() { return id; } public void setName(String name) { this.name = name; } public void setId(int id) { this.id = id; } } can be replaced simply with a record that looks like this: public record Student(String name, int id){ } And not only it replaces the boilerplate code I showed you, it also automatically overrides Object#equals(Object) , Object#hashCode() , and Object#toStr...
