C# Sharp to Java - Practice Exercises Java

Lesson 8:

File management

Exercise 8.11:

C# Sharp to Java


Create a basic C# Sharp to Java translator.

It must accept a C# Sharp source files, and create an equivalent Java source file. It will receive the file name in the command line, and it must translate at least:

"Main()" into "main( String[] args )"
"string" into "String"
"bool" into "boolean"
"Console.WriteLine" into "System.out.println"
" : " into " extends " if it is in the same line as the word "class" (and any further improvements you may think of, such as strings handling, or converting a ReadLine to a try-catch block).

Source Code:

import java.util.*;
public class CsharpToJava
	public static void main(String[] args)
		String line;
		String name;

		if (args.length < 1)
			name = new Scanner(;
			name = args[0];
		} iFile = new; iFileBufferedReader = new; oFile = new + ".java");

			line = iFileBufferedReader.readLine();

			if (line != null)
				line = line.replace("bool ", "boolean ");
				line = line.replace("string ", "String ");
				line = line.replace("Console.WriteLine", "System.out.println");

				oFile.write(line + System.lineSeparator());

		} while (line != null);
