OuterClass.java
public class OuterClass
{

private String name = "John";

public void greetInEnglish()
{
class SayHello
{
/*
* We cannot declare static variable or static methods in a local
* class.
*/


public static String message = "Welcome";

public static void greet()

System.out.println(message);
}
}

SayHello sayHello = new SayHello();

LocalClassTest.java
public class LocalClassTest
{
public static void main(String args[])
{
OuterClass outerClass = new OuterClass();
outerClass.greetInEnglish();
}

}
