Exception in thread 'main' java.lang.NoSuchMethodError: main
Error message
Exception in thread 'main' java.lang.NoSuchMethodError: main
What broke
The Java application failed to start because it could not locate the main method, which is the entry point for any Java application. This typically occurs when the method is missing or incorrectly defined.
Why it broke
This broke because the main method must be defined as 'public static void main(String[] args)' in order for the Java Virtual Machine (JVM) to recognize it as the starting point. If the method signature is incorrect or if the class is not public, the JVM will throw this error.
How to fix
To fix this, ensure that the main method is correctly defined in your class. It should be public, static, and return void, with a single parameter of type String array.
Code fix
public class MyClass { public static void main(String[] args) { System.out.println("Hello, World!"); } }Explained by ErrorOracle
Prevention tip
It should be public, static, and return void, with a single parameter of type String array.
