I need help writing this project in Java

Write a program that will check Java file for syntax errors. The program will ask for an input-file name and output-file name and will then copy all the code from the Java input-file to the Jave output file, but with following changes:

Any syntax error found in the Java input file will be corrected:

Missing semicolon

Missing compound statements (Curly braces)

All the comments have to start with // and end with a period

Four spaces should be used as the unit of indention. Tabs must be set exactly every 8 spaces (not 4)

Your program should have a simple GUI (Graphical User Interface). Use ArrayList or LinkedList class to solve the problem.

Thoroughly test your code for any possible input. Do not hardwire the output.

Example Input file: JavaInput.java

//Program to calculate sum of two numbers.

public class TestProgram{

public static void main(String[]args)

{int n1,n2; n1=5; n2=10

int answer=0; answer=n1+n2;

System.out.println(answer);}}

Example Output file: JavaOutput.java

//Program to calculate sum of two numbers.

public class TestProgram

{

public static void main(String[]args)

{

int n1,n2;

n1=5; n2=10

int answer=0;

answer=n1+n2;

System.out.println(answer);

}

}
