    Default reformatting java code problem

    hello, i would really apreciate any help on this one.. i have just started file i/o in java and already the homework is bugging me.
    I am to write a program that reformats java source code from the next-line brace style to the end-of-line brace style. for example the following code :
    public class Test
    {
          public static void main(String[] args)
         {
           // some statements
         }
     
    }

    would be reformatted to :

     
    public class Test{
          public static void main(String[] args){
           // some statements
          }
     
    }
    my attempted code so far is below.. i don't know if i can use concat() in this instance and if i am even doing anything right... please help.. thanks.

     
    import java.io.*;
    import java.util.*;
     
    public class Main {
     
    	public static void main(String[] args) throws Exception {
     
    		File file = new File("C:\\JackTest\\test.txt");
    		format(file);
     
    	}
     
    	public static void format(File f) throws Exception {
     
    		Scanner input = new Scanner(f);
     
    		String[] lines = new String[7];
     
    		while (input.hasNext()) {
     
    			for (int i = 0; i < 7; i++) {
     
    				lines[i] = input.nextLine();
     
    				if (lines[i].startsWith("{")) {
     
    					lines[i-1].concat("{");
    					// i am stuck here.. 
     
    				}
     
     
     
    			}
     
    		}
    	}
    }
