Editing Java syntax (section)

====Modifiers====
Modifiers are keywords used to modify declarations of types and type members. Most notably there is a sub-group containing the access modifiers.

* '''<code>abstract</code>''' - Specifies that a class only serves as a base class and cannot be instantiated.
* '''<code>static</code>''' - Used only for member classes, specifies that the member class does not belong to a specific instance of the containing class.
* '''<code>final</code>''' - Classes marked as <code>final</code> cannot be extended from and cannot have any subclasses.
* '''<code>strictfp</code>''' - Specifies that all floating-point operations must be carried out conforming to [[IEEE 754]] and forbids using enhanced precision to store intermediate results.

=====Abstract class=====

=====Final class=====
{{Excerpt|final (Java)#Final classes}}

=====Access modifiers=====
The ''access modifiers'', or ''inheritance modifiers'', set the accessibility of classes, methods, and other members. Members marked as <code>public</code> can be reached from anywhere. If a class or its member does not have any modifiers, default access is assumed.

<syntaxhighlight lang="java">
public class Foo {
    int go() {
        return 0;
    }

    private class Bar {
    }
}
</syntaxhighlight>

The following table shows whether code within a class has access to the class or method depending on the accessing class location and the modifier for the accessed class or class member:
