Java Tutorial : Java Static Nested Classes

OuterClass.java

public class OuterClass
{

    private int outerVariable = 10;
    private static int staticOuterVariable = 200;

    public void outerDisplay()
    {
        System.out.println("outerDisplay method has been called...");
    }

    public static void staticOuterDisplay()
    {
        System.out.println("staticOuterDisplay method has been called...");
    }

    static class StaticNestedClass
    {
        int innerVariable = 2000;

        public void innerDisplay()
        {
            System.out.println("innerDisplay method has been called...");
            System.out.println("innerVariable : " + innerVariable);
            System.out.println("staticOuterVariable : " + staticOuterVariable);
            staticOuterDisplay();

            // System.out.println("outerVariable : " + outerVariable);
            // outerDisplay();
        }
    }

}

StaticNestedClassTest.java

public class StaticNestedClassTest
{

    public static void main(String[] args)
    {
        OuterClass.StaticNestedClass nestedObj = new OuterClass.StaticNestedClass();
        nestedObj.innerDisplay();
    }

}

Output

innerDisplay method has been called...
innerVariable : 2000
staticOuterVariable : 200
staticOuterDisplay method has been called...
