When we will compile it, then we can say this_class will be Sample class and super_class will be Object class.

super_class: It represents fully qualified name of the immediate super class of current class.

this_class: It represents fully qualified name of the class file.

access_flags: It provide the information about the modifiers which are declared to the class file.

constant_pool: It represents the information about constants present in constant pool file.

constant_pool_count: It represents the number of the constants present in the constant pool (When a Java file is compiled, all references to variables and methods are stored in the class’s constant pool as a symbolic reference).

class file version where the digits before the decimal point represent the major_version and digits after decimal point represents the minor_version. Note: Internally jdk 1.5 version means 49.0 and 1.6 means 50.0 and 1.7 means 51.0 etc. There is a run time exception which I have highlighted in below image.

Step 5: Now on 2nd command prompt window try to run the above compiled code class file and see what happen. Step 4: Now on 1st command prompt compile the any valid. And check for Java compiler version ad JVM version. Step 3: Open a second command prompt window and set the path of bin folder of installed jdk installed during 2nd step.

Step 1: Open a command prompt window and try to check java compiler version and JVM version using following commands respectively (Highlighted text in image are the commands)

This demonstration is for Windows OS as follows: If we will try to execute we will get run time exception. class file cannot be executed by lower version JVM. class file can be executed by high version JVM but higher version compiler generated. We denotes the version of class file as M.m where M stands for major_version and m stands for minor_version JVM will use these versions to identify which version of the compiler generates the current. minor_version & major_version: These both together represents.Note: This can vary depending on how much you remove the. you will get run time exception ( See the highlighted text in below image): Step 4: Now try to run this using java Sample command and see the magic i.e. Step 3: Now erase at least single symbol from this Sample.class file from starting of file and save it. java file named as Sample.java as follows and follow step by step process on your system. Now let’s see what happen when JVM will not find valid magic number. The predefined value will be in hexadecimal form i.e. class file is generated by valid compiler or not.

This is a predefined value which the JVM use to identify whether the.

magic_number: The first 4 bytes of class file are termed as magic_number.
