Java Classes Since the Java programming language is object-oriented, code is organized using object classes. The bytecode objects produced by the Java compiler are called “class files”, or simply “classes”, and are named using the .class file name extension. The isCOBOL Compiler, isCOBOL Runtime Framework, and isCOBOL Debugger are distributed as Java classes. After compiling a COBOL program with the isCOBOL Compiler, the COBOL object files are Java class files.
