Identify the incorrect statement about compilation and execution of java programs
javac helps in compiling the java program and creates the .class files
java runs the programs using the bytecode in .class files
java runs the programs using the source code in .java files
javac is in the JDK package and java is in the JRE package
Correct Answer : C
The program written for execution is saved as .java and this is called source code. This is compiled using command javac as javac filename.java which produces bytecode (.class file) which is portable. This bytecode is passed to interpreter for running using the command java as java filename. JDK is Java Development Kit which includes javac, jar, debugging tools and JRE is Java Runtime Environment which includes java, javaw and libraries.
