Overview of Java Programming Language

• Java programming language is a general purpose object oriented language.
• It is designed to be simple enough that many programmers can achieve fluency in the language.
• The Java programming language is related to C and C++ but is organized rather differently, with a number of aspects of C and C++ omitted and a few ideas from other languages included.
• The Java programming language is strongly and statically typed.
• This specification clearly distinguishes between the compile time errors that can and must be detected at compile time and those that occur at run time.
• Compile time normally consists of translating programs into a machine independent byte code representation.
• Run-time activities include loading and linking of the classes needed to execute a program, optional machine code generation and dynamic optimization of the program and actual program execution.
• The language does not include any unsafe constructs, such as array accesses without index checking, since such unsafe constructs would cause a program to behave in an unspecified way.
• The Java programming language is normally compiled to the bytecode instruction set and binary format defined in The Java Virtual Machine Specification, Java SE 8 Edition.
