Fix Java @Override Errors

When the @Override annotation is used, the compiler will verify if the current method correctly overrides a method in the parent class or interface. If there is an error with @Override, it is usually due to one of the following reasons and can be resolved in the following ways:

1. Error in method signature: the method’s name, parameter list, and return type must match exactly with those of the method in the parent class or interface. If the error message indicates a method signature error, check if the method name, parameter list, and return type are correct.

@Override
public void myMethod(int param) { // 错误示例：方法签名错误
    // ...
}

1. Override this function
2. Override the following

public class MyClass {
    // ...
}

public class MySubClass extends MyClass {
    // 错误示例：父类中不存在myMethod方法，不需要使用@Override注释
    @Override
    public void myMethod() {
        // ...
    }
}

1. inheritance

public class MyClass {
    private void myMethod() {
        // ...
    }
}

public class MySubClass extends MyClass {
    // 错误示例：父类中的myMethod方法为私有方法，无法被覆盖
    @Override
    public void myMethod() {
        // ...
    }
}

1. The compiler version is not compatible: the @Override annotation was introduced in Java 1.5, so using an older version of the Java compiler may result in errors. Try upgrading or changing the compiler version.
2. Importing the wrong class or interface can lead to the compiler being unable to find methods in the parent class or interface. Make sure to check if the imported class or interface is correct.

If the above methods do not solve the problem, please provide specific error messages and code examples to better assist you in resolving the issue.
