JAVA was developed by Sun Microsystems INC in 1991, later noninheritable by Oracle Corporation. it absolutely was developed by James goose and Patrick Naughton. it's a straightforward artificial language. Writing, aggregation and debugging a program is simple in java. It helps to make standard programs and reusable code.
Java word
Before we have a tendency to begin learning Java, lets get aware of common java terms.
Java Virtual Machine (JVM)
This is usually referred as JVM. Before, we have a tendency to discuss concerning JVM lets see the phases of program execution. Phases area unit as follows: we have a tendency to write the program, then we have a tendency to compile the program and finally we have a tendency to run the program.
1) Writing of the program is in fact done by java technologist such as you and American state.
2) Compilation of program is completed by javac compiler, javac is that the primary java compiler enclosed in java development kit (JDK). It takes java program as input and generates java bytecode as output.
3) In third part, JVM executes the bytecode generated by compiler. this is often referred to as program run part.
So, currently that we have a tendency to understood that the first perform of JVM is to execute the bytecode created by compiler. every package has totally different JVM, but the output they turn out when execution of bytecode is same across all in operation systems. that's why we have a tendency to decision java as platform freelance language.
