The Myth of goto in Java
The infamous goto statement has long been a source of controversy in the world of programming. While most Java enthusiasts deny its existence, the keyword itself remains a part of the language. So, what gives?
The Non-Usage of goto
James Gosling, the creator of the Java Virtual Machine (JVM), originally included goto support. However, he later deemed it unnecessary and removed the feature. The rationale behind this decision lies in the superior alternatives available in Java. Statements like break and continue provide more readable and structured control flow, while extracting code into methods allows for modularity and code reuse.
Why Keep It, Then?
Despite its non-usage, goto remains a keyword in Java for historical reasons. Java was designed to be backward-compatible with C , which does support goto statements. Thus, including goto as a reserved keyword maintained this level of compatibility.
Conclusion
While goto is technically a keyword in Java, its usage is discouraged due to the presence of more appropriate control flow mechanisms. The main reason goto is unnecessary is that usually it can be replaced with more readable statements (like break/continue) or by extracting a piece of code into a method. Thus, you'll rarely, if ever, encounter goto in modern Java code.
