casting int[] to char[] does not work properly


when you do

char number = (char) buffer1[j];

you actually put the integer value in the char, but char with a value of, let's say 43, is the "+" plus, according to the ascii table, and that's why you get the output you are talking about.

i'll give you an example:

let's say plik1.txt contains

45, 66
46, 67

then after your reading numberArray1 and numberArray2 contains

["45", "66"]
["46", "67"]

and then buffer1 and buffer2 contains

[45, 66]
[46, 67]

now buffer11 and buffer22 will contain the save thing, but when you try to print them, java will print the ASCII sign corresponding with this number, meaning:

- B
. C

so, for conclusion, your "casting int[] to char[]" works perfectly, it's just you thought it'll do something else

type casting classes mimiking enums
First, your Parse method should put a constraint on T: public static T Parse<T>(int value) where T : MyEnum Second, you can make it protected instead and implement a casting operator in each of the derived enums this way: public static explicit operator MyEnumChild1(int value) { return Parse<MyEnumChild1>(value); } And use it in a more classic way: MyEnumChild1 mec1 = (MyEnu
