举一个内部类、局部内部类、静态内部类、匿名内部类的代码例子。

内部类、局部内部类、静态内部类、匿名内部类的代码例子如下：

1. 成员内部类的例子：

public class OuterClass {
    private int x = 10;

    public class InnerClass {
        public void printX() {
            System.out.println("x is " + x);
        }
    }
}

2. 局部内部类的例子：

public class OuterClass {
    private int x = 10;

    public void printX() {
        class LocalInnerClass {
            public void printOuterX() {
                System.out.println("Outer x is " + x);
            }
        }

        LocalInnerClass localInner = new LocalInnerClass();
        localInner.printOuterX();
    }
}

3. 静态内部类的例子：

public class OuterClass {
    private static int x = 10;

    public static class StaticInnerClass {
        public void printX() {
            System.out.println("x is " + x);
        }
    }
}

4. 匿名内部类的例子：

public class OuterClass {
    public void printMessage() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.println("Hello from anonymous inner class!");
            }
        }).start();
    }
}
