Where does the source code come from?

Source code is generally understood to mean programming statements that are created by a programmer with a text editor or a visual programming tool and then saved in a file.

What is the source code in Java?

Source code refers to the high-level code or assembly code that is generated by a human/programmer. In simple, we can say source code is a set of instructions/commands and statements which is written by a programmer by using a computer programming language like C, C++, Java, Python, Assembly language, etc.

What kind of file contain Java source code?

When Java source file is compiled by Java compiler it is converted into Java class file with .class extension.

  • The Java class file contains Java bytecode (highly optimized set of instructions) which is executed by Java Virtual Machine (JVM).
  • .class file contains symbols and each bytecode instruction is stored into one byte exactly.

    What does the Java compiler translate Java source code to?

    A Java Compiler javac is a computer program or set of programs which translates java source code into java byte code. The output from a Java compiler comes in the form of Java class files (with .class extension). The java source code contained in files end with the .java extension. The file name must be the same as the class name, as classname.java.

    What is the extension for Java source code files?

    A file with the JAVA file extension (or less commonly the .JAV suffix) is a Java Source Code file written in the Java programming language.

    How is Java code compiled?

    Java source code is compiled down to bytecode by the Java compiler. The bytecode is executed by a Java Virtual Machine (JVM). Modern JVMs use a technique called Just-in-Time (JIT) compilation to compile the bytecode to native instructions understood by hardware CPU on the fly at runtime.
