yes, I test it with J2SE1.3, when I access a instance-method by the
class-name directly,
the compiler's output is:
"non-static method m2( ) cannot be referenced from a static context"
"non-static method m2( ) cannot be referenced from a static context"
when compiler says "static context", it means Class-Name(Class-Name is a
static context),
not try/catch/finally block.
public class MyTest {
public void m0(){
MyUtility.m2();
}
public static void m1(){
MyUtility.m2();
}
}
class MyUtility {
public void m2(){}
}
Happy new year! :-)
