Understanding "Code Too Large" Compilation Error in Java

Java enforces limitations on the size of code that can be compiled into bytecode. Beyond this limit, you may encounter the "code too large" compilation error.

This issue arises when a method becomes excessively large, exceeding the maximum allowed size. In your case, your function contains a significant number of lines assigning values to an array.

Overcoming the Error

To resolve this error, Java introduces a specific limit: a single method in a class can contain up to 64KB of bytecode. Exceeding this size triggers the "code too large" error.

Alternative Solution

While overcoming the bytecode limit may be possible, it's not an ideal approach. Instead, consider optimizing your code by utilizing external resources. A preferred solution is to store large amounts of data in a .properties file and load it into your application using java.util.Properties.

Follow these steps:

1. Create a .properties file and add your data.
2. Place the file on your classpath.
3. Load the file menggunakan Java Properties API, as shown in the example code you provided.

This approach promotes code clarity, readability, and maintainability.
