    Default Help With illegal start of expression

    I have gotten many errors on my "public classes" saying illegal start to expressions and semicolons. Am i missing a bracket somewhere or is it something else.

        //java packages
    	import java.util.Scanner;
     
     
        public class PiggyRunner
    		{ //start PiggyRunner
    	public static void main (String[] args)
     
    	{ //start main
     
     	Scanner keyboard = new Scanner (System.in);
     
        //Variables Set Data
    	 double total;
    	 private int pennies;
    	 private int nickels;
    	 private int dimes;
    	 private int quarters;
    	 private int halfdollars;
    	 String cont = "";
     
     
    	public Piggy() //constructor
    	{ //start CalculatorAmounts
    	 total = 0.0;
    	 pennies = 0;
    	 nickels = 0;
    	 dimes = 0;
    	 quarters = 0;
    	 halfdollars = 0;
       } //end CalculatorAmounts
     
     
    	public void Piggy(double tot, int pens, int niks, int dim, int quart, int hfdoll)
         { //SetData
    	 pennies = pens;
    	 nickels = niks;
    	 dimes = dim;
    	 quarters = quart;
    	 halfdollars = hfdoll;
    	  } //SetData
     
     
     
    	public void calculatePiggy()
      { // begin calculatePiggy
        total = (.01*pennies);
    	total = (.05*nickels);
    	total = (.10*dimes);
    	total = (.25*quarters);
    	total = (.50*halfdollars);
      } // end calculatePiggy
     
     
    	public void printValue()
    	{//start PrintWealth
      System.out.printf (" Your total value of pennies is %.2f \n",
      pens );
      System.out.printf("");
      System.out.printf (" Your total value of nickels is %.2f \n",
      niks );
      System.out.printf("");
      System.out.printf (" Your total value of dimes is %.2f \n",
      dim );
      System.out.printf("");
      System.out.printf (" Your total value of quarters is %.2f \n",
      quart );
      System.out.printf("");
      System.out.printf (" Your total value of halfdollars is %.2f \n",
      hfdoll );
      System.out.printf("");
     }//end PrintWealth
    	if ( total<5 )
    	{ //begin if tot<5
    	   System.out.println("HA HA HA HA I know who isn't going anywhere soon!");
    	} //end if tot<5
     
    	if ( total>5 && total<15 )
    	{ //begin if tot>5 && tot<15
       		System.out.println("You got enough for a movie ticket!");
    	} //end if tot>5 && tot<15
     
    	if ( total>15 && total<25 )
    	{ //begin if tot>15 && tot<25
    	    System.out.println("Thats what happens when you save your pennies!");
    	} //end if tot>15 && tot<25
     
    	if ( total>25 )
    	{ //begin if tot>25
    	   System.out.println("Make it Rain!!!");
    	} //end if tot>25
     
     
     
     
     
    	}//end main
     
    	}//end PiggyRunner

    Could be mismatched {}s
    If the } //end main is supposed to end the main() method, then there is a problem with defining methods inside of methods which can't be done.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    I think you may be nesting the constructor inside the main() method which makes no sense. The compiler will grumble when it hits the "public" of the constructor. That and mismatched braces are a common source of "illegal start of expression" messages.

    When you post code, use the "code" tags - put [code] at the start of the code and [/code] at the end. This will allow the formatting to be visible in the post.

    The ending } for the main() method should be before any other method definitions.
