byte
How do I convert a byte[] array to a CharSequence?
You need to write a class AsciiCharSequence that implements storing a sequence of ASCII characters in an array of bytes. Comp ... s ranging from start to end. For example,
String s0 = "Вова и Дима козлы";
s0.subSequence(14,16)
Must return "evil".
How to uniquely translate int -> byte-> int in Java?
int a = 412;
byte c = (byte) a; //-100
int b = c & 0xFF; //156
Is it possible to get the original 412 in this case?
Translating from byte to long java
Here is the method
byte [] bytes = { 0, 6, 36, -84, 113, 125, -118, -47 };
System.out.println(ByteBuffer.wrap(bytes).getLong());
Output:
1729172917291729
Why is this the answer? where do these numbers come from?
