WebConsider the following generic method. The first generic type argument is the same as the type of the formal argument. But there is no such relationship for the second generic type argument. Therefore, the compiler has no way of inferring the second generic type argument in any call to this method. void X(T1 obj) { } WebThe reason is the type parameter T can be replaced by any of the type argument e.g. Clazz or Clazz etc. But static fields/methods are shared by all non-static objects of the class. But static fields/methods are … bata mujer corta
