Dear sir in the above code it should throw NoSuchMethodException becouse showData() is not in class first that is on run time. But it is genrating a compile time error that can't resolve symbol why sir? and if it true then when does NoSuchMethodException is thrown?

NoSuchMethodError happens at runtime when the .class files don't match the source code that the compiler saw. Imagine two classes where code in one class A calls a method in a second class B. First, compile both classes, then modify B to remove that method and recompile only B. Now when you run A, you'll see this exception.
In your case, the compiler can see the method is missing already, so it refuses to even compile the code.
