In most cases a C++ application will consume less memory than an equivalent Java application due to the large overhead of Java's virtual machine, class loading and automatic memory resizing. For programs in which memory is a critical factor for choosing between languages and runtime environments, a cost/benefit analysis is needed.
This makes C language even faster. In Java, such code must reside in external ... The minimum of code needed to compile for C++ is a function, for Java is a class.

In Java, this will mean that the method in the derived class will implicitly override the method in the base class, even though that may not be the intent of the designers of either class. To mitigate this, C# requires that if a method is intended to override an inherited method, the override keyword must be specified.
The way to use the page that note 42 refers to to describe that Java is faster than C in some cases is clearly cheat! The only one listed in that page that Java is faster than C is the 240 vs 260/250 fps one -- the Original C Code vs Jake2-0.9.4 JRE1.5 fastjogl/lwjgl. The speed of programs that using OpenGL is largely depended on OpenGL.
Notable programming sources use terms like C-style, C-like, a dialect of C, having C-like syntax. The term curly bracket programming language denotes a language that shares C's block syntax. [1] [2] C-family languages have features like: Code block delimited by curly braces ({}), a.k.a. braces, a.k.a. curly brackets; Semicolon (;) statement ...
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
Value types can sometimes be faster and smaller than classes with references. [12] [13] [14] For example, Java's HashMap is implemented as an array of references to HashMap.Entry objects, [15] which in turn contain references to key and value objects. Looking something up requires inefficient double dereferencing.
