How do you check if a Java program has been successfully compiled?

To check if a Java program has been successfully compiled, you can follow these steps:

Compile the Java Program: Use the javac command in the terminal to compile your Java file. For example:
```
javac YourProgram.java
```
Check for Errors: If there are any syntax errors or issues in your code, the compiler will display error messages in the terminal. If there are no errors, the command will complete without any output.
Look for the Class File: After successful compilation, a .class file will be generated in the same directory as your Java file. For example, if your Java file is YourProgram.java, you should see YourProgram.class.
Run the Program: You can further verify by running the compiled program using the java command:
```
java YourProgram
```

If the program runs without issues, it indicates that the compilation was successful.
