Must Override a Superclass Method' Errors After Importing a Project into Eclipse

Must Override a Superclass Method' Errors after importing a project into Eclipse

Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).

Go to your project/IDE preferences and set the Java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from Eclipse.

Must override a superclass method error when using m2e-android

A new morning a brand new mind set :-)

I added a space to AndroidManifest.xml and saved the file. This triggered some kind of cache cleanup or eclipse android setting reset and all "must override a superclass method" disappeared.

It seems that my eclipse/android/maven was in a state which was invalid.

Why do I get must override a superclass method with @Override?

Check the project's properties and verify that Java Compiler -> Compiler compliance level is set to 1.6 (or a later version).

It worked for me... i am using eclipse 2021.... and ..

The method must override a superclass method

It sounds like the JDK compliance level of your project is set to 1.5. (The version of Java installed on the machine only determines how high you can set the compliance level.) You can check this in Eclipse by opening the project properties (right click on the project name, then select "Properties") and selecting "Java Compiler" on the left.

In Java 1.6, the @Override annotation can (and should) be used on methods that are defined in implemented interfaces. Java 1.5 did not allow this.

Method...Must Override a Superclass Method (Latest SDK)

I think you are using java compiler 1.5, make it 1.6,because @Override of interface's methods is introduced after 1.5.

In Eclipse,

Window -> Preferences -> Java -> Compiler -> Compiler Compliance Level -> select
1.6

Eclipse: always notice error when use @Override

Java 5 only properly supports this annotation on methods you override when subclassing. Starting with Java 6 you can also use this annotation on methods that implement methods from an interface.

@Override gives error in eclipse?

You're getting the error because you're using Java 1.5 which does not support @Override annotations for implementation overrides. Go into the Eclipse settings and set the language level to 1.6.

EDIT - to change the language level go To Project > Properties > Java Compiler and set the language level there. You may need to click to enable project specific settings.

eclipse override method error on java 6, compiler 1.6

1) You can't Override private methods.

2) As soon as eclipse/compiler see @Override statement, it tries to look for relevant protected (or) public method in super class, which is not there. That is why compiler error.

The method must override or implement a superclass method

You don't need to use @override annotation in your method implementation as you are not overriding the methods. You are just implementing the interface methods. This annotation is required when your override any super class methods.

Remove the @Override annotations and it should be fine.
