Explain the java b symbol.

Question

I look at java bytecode and understand almost everything.I saw the symbol [B on java bytecode.What does it mean?

Al German · Accepted Answer

Java b means a byte array. In the Java descriptor syntax, a [ at the beginning means an array. There's a one letter code for each primitive type - B = Byte, C = Char, S = Short, Z = Boolean, I = Int, J = Long, F = Float, and D = Double. Object types are represented by L, followed by the classname, followed by a semicolon. So for example, a String[][][] would have the descriptor [[[Ljava/lang/String;.
