The C++ standard permits garbage collection, but does not require it. Garbage collection is rarely used in practice. C++ can allocate arbitrary blocks of memory. Java only allocates memory via object instantiation. Arbitrary memory blocks may be allocated in Java as an array of bytes. Java and C++ use different idioms for resource management.
The original Java memory model developed in 1995, was widely perceived as broken, [1] preventing many runtime optimizations and not providing strong enough guarantees for code safety. It was updated through the Java Community Process, as Java Specification Request 133 (JSR-133), which took effect back in 2004, for Tiger (Java 5.0). [2] [3]
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]
C programming language (1973) got its name because the language BCPL was replaced with B, and AT&T Bell Labs called the next version "C". Its purpose was to write the UNIX operating system. [50] C is a relatively small language, making it easy to write compilers. Its growth mirrored the hardware growth in the 1980s. [50]

Write once, run anywhere (WORA), or sometimes Write once, run everywhere (WORE), was a 1995 [1] slogan created by Sun Microsystems to illustrate the cross-platform benefits of the Java language. [ 2 ] [ 3 ] Ideally, this meant that a Java program could be developed on any device, compiled into standard bytecode , and be expected to run on any ...
1 Novice (0~99 points) The examinee requires more intensive study and training as he/she lacks knowledge and understanding of both technical and business field of ICT. 2 Advanced beginner (100~399 points) The examinee only has an understanding of the theory and practice in the technical and business field of ICT. 3 Competent (400~699 points)
ESC/Java and ESC/Java2 – Based on Java Modeling Language, an enriched version of Java Frama-C – An open-source analysis framework for C, based on the ANSI/ISO C Specification Language (ACSL). Its main techniques include abstract interpretation, deductive verification and runtime monitoring .
