I cant believe my eyes?

[james gong]

class TestClass
{
int val=5;
public static void main(String args[])
{
if( val > 4 )
{ System.out.println( "Test A" );
}
else if( val > 9 )
{ System.out.println( "Test B" );
}
else System.out.println( "Test C" );
}
}
I had thought the code would compile clearly ,but the compiler complain that :Can't make a static reference to nonstatic variable val in class TestClass.would you please give me a reason for the result.

hii..
Static methods can't access instance variables(non static member variables).In the above code "val" is not static..and trying to access "val" from main method which is a static method will give a compiler error.

relax and view the questions carefully u will see the reasons urself

hi
u can access val thro a object of TestClass only inside a static method like
TestClass obj = new TestClass()
obj.val
hope this clarifies

public static void main (String args[]) method is static method and execute and execute first when class is loaded ..... in that situation class doesn't get value of variable val ......
for solution of this problem either u can make val variable is a static our create a object of class in to main method then
Object Name.variable name
