Question

Identify the false statement.

a. To compile a file named MyProgram.java, you type java MyProgram, but to execute the program you type java MyProgram.java.
b. When you compile a program, sometimes one error in syntax causes multiple error messages.
c. In Java, if a class is public, you must save the class in a file with exactly the same name and a .java extension.

Answer 1

The false statement is option a, which incorrectly describes the commands for compiling and executing a Java program. The correct process involves using 'javac' for compilation and 'java' for execution, without the '.java' extension for the latter.

Step-by-step explanation:

Identifying the false statement among the given options relating to Java programming, we find that option a is incorrect. The correct procedure to compile a Java file is to type javac MyProgram.java in the command line. This will compile the source code in the MyProgram.java file into bytecode. The resulting bytecode file is named MyProgram.class and is the file that the Java Virtual Machine can execute. To run the compiled program, you should type java MyProgram without the .java extension.

It is true that a single syntax error in the code can cause multiple error messages during compilation (option b). Furthermore, in Java, the public class name must match the filename (option c), emphasizing the language's requirements for source code organization.
