Generally, Java compilers are run and pointed to a programmer’s code in a text file to produce a class file for use by the Java virtual machine ( JVM) on different platforms.
The programmer then runs a compiler for the appropriate language, specifying the name of the file that contains the source statements.Īt run time, the compiler first parses (analyzes) all of the language statements syntactically and then, in one or more successive stages or "passes,” builds the output code, making sure that statements that refer to other statements are referred to correctly in the final code. The resulting file contains what are called the source statements. Programmers typically write language statements in a given programming language one line at a time using a code editor or an integrated development environment (IDE). Java compilers include the Java Programming Language Compiler (javac), the GNU Compiler for Java (GCJ), the Eclipse Compiler for Java (ECJ) and Jikes. A Java compiler is a program that takes the text file work of a developer and compiles it into a platform-independent Java file.
