Java: double vs float

Question

In another Bruce Eckel exercise, the code I\'ve written takes a method and changes value in another class. Here is my code:

class Big {
  float b;
}

public         


        

Answer 1

Yes, but you have to specify that they are floats, otherwise they are treated as doubles:

z.b = 2.2f

The 'f' at the end of the number makes it a float instead of a double.

Java won't automatically narrow a double to a float.
