You can use any editor that will save your file in text format. | | 2. | Compile the source file. | | 3. | Run the bytecode. | | 4. | Replace "Welcome to Java" with "My first program" in the program; save, compile, and run the program. You will see the message "My first program" displayed. | | 5. | Replace main with Main , and recompile the source code.
