push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack (wide index is constructed as indexbyte1 << 8 | indexbyte2) ldc2_w 14 0001 0100 2: indexbyte1, indexbyte2 → value
Java reads and writes normal UTF-8 to files and streams, [62] but it uses Modified UTF-8 for object serialization, [63] [64] for the Java Native Interface, [65] and for embedding constant strings in class files. [66] The dex format defined by Dalvik also uses the same modified UTF-8 to represent string values. [67]
Class names in Java, when fully qualified, are traditionally dot-separated, such as "java.lang.Object". However within the low-level Class reference constants, an internal form appears which uses slashes instead, such as "java/lang/Object". The Unicode strings, despite the moniker "UTF-8 string", are not actually encoded according to the ...
UTF-8-encoded, preceded by varint-encoded integer length of string in bytes Repeated value with the same tag or, for varint-encoded integers only, values packed contiguously and prefixed by tag and total byte length — Smile \x21
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
Object type Marker byte Encoded data nil: nil: ... UTF-8 string, nnnn is # of chars, else 1111 then int count, then bytes ... Any class implementing this protocol can ...
C++11 extended this further, to make classes act identically to POD objects in many more cases. ^c pair only ^d Although Perl doesn't have records, because Perl's type system allows different data types to be in an array, "hashes" (associative arrays) that don't have a variable index would effectively be the same as records.
If a class does not specify its superclass, it implicitly inherits from java.lang.Object class. Thus all classes in Java are subclasses of Object class. If the superclass does not have a constructor without parameters the subclass must specify in its constructors what constructor of the superclass to use. For example:
