Quick Answer

Resolve missing method errors.

Understanding the Issue

This runtime error occurs when a method is not found, usually due to version mismatches or compilation issues.

The Problem

This code demonstrates the issue:

Java Error 
// Compiled against different library version
object.missingMethod();

The Solution

Here's the corrected code:

Java Fixed 
// Verify method existence:
try {
    object.getClass().getMethod("methodName");
} catch (NoSuchMethodException e) {
    // Handle missing method
}

// Solutions:
// 1. Recompile with correct dependencies
// 2. Check library versions
// 3. Clean and rebuild project
// 4. Use dependency management (Maven/Gradle)

// Version check:
String version = LibraryClass.class.getPackage()
    .getImplementationVersion();

Key Takeaways

Maintain consistent dependency versions across builds.
