Why the byte code is verified?
when we compile a file in java, it creates a byte code which later on gets interpreted to machine understandable code. byte code is not machine language. where system understands only machine language. hence the interpretation of byte code is required.
What is the Byte code definition?
Java compiler produces an intermediate code after compilation, understandable by JVM is called Byte Code.
What is BYTE Code in java?
Java byte code is the code that is output by the Java compiler. Byte code is not machine code, it must be interpreted to create the machine code. This is handled by the Java virtual machine. Pretty much every platform produced today has a Java virtual machine implementation, so the same byte code can be executed upon any machine. Byte code can be regarded as being the native language of the virtual machine, as opposed to machine code which is the native language of the physical machine.
What is expanding opcode?
A code that leaves a spare bit to indicate that if that bit is set, consider this byte and the next byte to be defining the entire code.
How java is fast?
Java is not fast. Compared to equivalent code compiled to native machine code it is extremely slow. However, it is somewhat faster than many other interpreted languages because the source code compiles to Java byte code which is suitable for interpretation by any Java virtual machine. Interpreting byte code is much quicker than interpreting source code and, unlike machine code, byte code is portable.
What will come after yota bytes?
Geop byte
What is the difference between runtime and compilation?
Compilation is generally the process of parsing the human-readable source code and turning it into machine-readable byte code. Runtime occurs during the execution of the byte code as a program. Examples: A compile-time error is an error that occurs while the source code is being turned into byte code. A runtime error is an error that occurs while the program is executing.
What is the purpose of a byte in Java?
Java coding uses byte as one of the programming directives to clarify commands. Byte can also be used in the Java code to save memory space when the need arises.
Does one byte in computer code represent 25?
No it represents 8
How many no of instructions does the java byte code has?
200 instructions only.
What is compiled code?
Compiled code is plain-text source code that is translated from an English-like, high-level language into either machine code or byte code by a program known as a compiler. Machine code is the native language of the machine, consisting of binary patterns that represent a sequence of machine instructions and their operands. Byte code is the native language of a virtual machine; a machine that only exists within a computer's memory. The virtual machine is simply a program that interprets the byte code in order to produce the actual machine code. Unlike machine code which must be compiled separately for each platform, byte code will run on any platform that has a corresponding virtual machine implementation.
How is java byte code is different from other low level language?
Java byte-code is the code which generate after the compilation of .java file.And this code is only understand by JVM(java virtual machine ) which understand it and execute it.In other languages this type of functionality is not available.
