The goto statement is not available in Java because it can lead to unstructured and difficult-to-read code. In the past, the use of the goto statement was common in programming languages like C and assembly, but it was later discovered that it can cause hard-to-debug problems, such as infinite loops and unreachable code.
Java, like many modern programming languages, was designed with structured programming principles in mind, and it encourages the use of control structures like loops, conditional statements, and methods to create well-structured and maintainable code. The designers of Java deliberately left out the goto statement to prevent programmers from using it to create complex and difficult-to-maintain code.
Instead of the goto statement, Java provides a set of structured control flow statements such as if-else, while, for, and switch statements that make the code more readable and maintainable. These statements can handle most of the control flow requirements of the program, and they allow for better modularization and code reuse.
Therefore, in Java, it is considered good practice to avoid using the goto statement and instead use the available structured control flow statements to write well-structured and maintainable code.
