How to implement a static member interface
package com.java2novice.nested.classes;
public class MyStaticMemberInterfaceTest
implements MyStaticMemberInterface.MyStaticInterface
{
public void implementMe()
{
System.out.println("Hey
I have implemented successfully!!!");
}
public static void main(String a[])
{
MyStaticMemberInterfaceTest
msi = new MyStaticMemberInterfaceTest();
msi.implementMe();
}
}
class MyStaticMemberInterface
{
public static interface MyStaticInterface
{
public void implementMe();
}
}
How to access top level class variables from static member classes
package com.java2novice.nested.classes;
public class MyStatMemClassAcsVars
{
public static String staticVar =
"You can access me!!!";
private String privVar =
"You cannot access me";
public static class ChildClass
{
public void myMethod()
{
System.out.println(staticVar);
System.out.println(privVar);
}
}
public static void main(String a[])
{
MyStatMemClassAcsVars.ChildClass
cc = new MyStatMemClassAcsVars.ChildClass();
cc.myMethod();
}
}
Give an example of basic non-static member class
package com.java2novice.nested.classes;
public class MyBasicNonStaticMemberClass
{
public class ChildClass
{
public void myMethod()
{
System.out.println("Hey
you have called me!!!");
}
}
public ChildClass
getInnerInstance()
{
return this.new ChildClass();
}
public static void main(String a[])
{
MyBasicNonStaticMemberClass
mbn = new MyBasicNonStaticMemberClass();
ChildClass
cc = mbn.getInnerInstance();
cc.myMethod();
}
}
How to initialise non-static member (local class) class
package com.java2novice.nested.classes;
public class MyNonStaticMemberClassInstance
{
public static void main(String a[])
{
ParentClass
pc = new ParentClass();
ParentClass.ChildClass
cc = pc.getInnerInstance();
cc.myMethod();
ParentClass.ChildClass
cc1 = pc.new ChildClass();
cc1.myMethod();
}
}
class ParentClass
{
public class ChildClass
{
public void myMethod()
{
System.out.println("Hey
you have called me!!!");
}
}
public ChildClass
getInnerInstance()
{
return this.new ChildClass();
}
}
