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
The Java class loader, part of the Java Runtime Environment, dynamically loads Java classes into the Java Virtual Machine. [1] Usually classes are only loaded on demand . The virtual machine will only load the class files required for executing the program. [ 2 ]
GRASP (Linux, UNIX) and pcGRASP (Windows) are written in C/C++, whereas jGRASP is written in Java (the "j" in jGRASP means it runs on the JVM). The jGRASP web site offers downloads for Windows, Mac OS, and as a generic ZIP file suitable for Linux and other systems. For languages other than Java and Kotlin, jGRASP is a source code editor and ...
A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM).A Java class file is usually produced by a Java compiler from Java programming language source files (.java files) containing Java classes (alternatively, other JVM languages can also be used to create class files).
The runtime overhead of added instrumentation is small (5–20%) and the bytecode instrumentor itself is very fast (mostly limited by file I/O speed). Memory overhead is a few hundred bytes per Java class. EMMA is 100% pure Java, has no external library dependencies, and works in any Java 2 JVM (even 1.2.x).

C++ does not have the keyword super that a subclass can use in Java to invoke the superclass version of a method that it wants to override. Instead, the name of the parent or base class is used followed by the scope resolution operator. For example, the following code presents two classes, the base class Rectangle, and the derived class Box.
