DESIGN Outside main class:

1. Create a List Array of type String
2. Assuming the user entry won’t exceed 100 lines before “exe” as input, set initial index of string to a class name(same as java file name) followed by a main function , set all other indices upto 99 as “ ” set 100 and 101 to “}” to end the main method block and class.
3. A separate class to implement compilation of a java file (.java) and creating a compiled file in the same directory
4. A separate class to run the compiled file and store the output in a file.

In main class:

1. User Interface: Console-based interface with the ">>>" prompt. Accepts user input for Java code snippets.
2. Input Processing: Parse and analyze user input. Append all the statements onto a file (.java)
3. Interpreter Engine: Compile the java file before running. Run the compiled java file and store the output in a file.
4. Output Display: Show results or errors based on the executed code.
5. Error Handling: Implement mechanisms to handle syntax errors, runtime exceptions, etc.
