    Default weekly hours for each employee

    I am working on writing a code that allows me to display the employees and their total hours in decreasing order of the total hours. i have the displaying of the array and the summing of the array down but i can't get the sorting algorithm to work. I was hoping that i could get someone to help me with it. ill take answers or ill even take help comments. but please someone help me, this sorting stuff is pissing me off. (When i compile i get 1 error message and it is on line 45 or where it says public void hours().)
    Here is what i have so far:
    import java.util.Arrays;
    import java.util.Collections;
     
    public class Employee {
    	public static void main(String[] args) {
     
     
    	int [] [] hours = {
    			{2, 4, 3, 4, 5, 8, 8},
    			{7, 3, 4, 3, 3, 4, 4},
    			{3, 3, 4, 3, 3, 2, 2},
    			{9, 3, 4, 7, 3, 4, 1},
    			{3, 5, 4, 3, 6, 3, 8},
    			{3, 4, 4, 6, 3, 4, 4},
    			{3, 7, 4, 8, 3, 8, 4},
    			{6, 3, 5, 9, 2, 7, 9} };
     
    	int [][] totalhours = new int[8][7];	
     
    	// Display the array
    	for (int row = 0; row < 8; row++)
    	{
    		for (int col = 0; col < 7; col++)
    			System.out.print(hours[row][col] + " ");
    		          System.out.println();
     
    	}
     
    		// sum rows of the array
    		int total;
     
    		for (int row = 0; row < hours.length; row++)
    		{
    			total = 0;
    					for (int col = 0; col < hours[row].length; col++)
    						total += hours[row][col];
     
    					System.out.println(" Total of row " + row + 
    								" is " + total);
    					totalhours [row][0] = total;
     
    		}
     
    		// sort the contents of the array in descending order
    		public void hours() {
    			int h;
     
    				Integer[][] hours = new Integer[] {
    					new Integer (34),
    					new Integer (28),
    					new Integer (20),
    					new Integer (31),
    					new Integer (32),
    					new Integer (28),
    					new Integer (37),
    					new Integer (41)
    				};
     
    				Arrays.sort(arrayToSort, Collections.reverseOrder());
     
    				for (Integer h : hours) {
    					System.out.println(h.intValue());
    				}
    		}
     
    		}
     
     
     
    }

    when i compile i get 1 error message and it is on line 45 or where it says public void hours().)
    What is the full text of the error message. Please copy and paste it here.

    Please edit you code and wrap it in code tags to preserve the formatting. Use the #icon or

    Those are weird compiler errors. What compiler are you using?
    Here is what the javac command outputs for me:
    TestSorts.java:138: cannot find symbol
    symbol  : variable var
    location: class TestSorts
             var = 2;
             ^

    I can't easily read you code because it has not been properly formatted. The ending } should be in alignment below the statement where the starting { is. Statements within the {} should be indented at least 3 spaces.

    Check that each of your method's beginning { and ending } are paired correctly.

    If you want help with your problem, you need to post properly formatted code. Especially when it looks like the problem is with mismatched {} or misplaced methods or other code.

    You don't need to post a second copy. You could edit the Post#1 and fix it there.

    Did you look at it after you posted it? Do a Preview before posting to see if the code is formatted.
    It looks the same as post#1. It needs to be fixed!
    You need to wrap the code in code tags. Press the Go Advanced button and use the #icon or
    see this: BB Code List - Java Programming Forums

    It should look like this:
      class WindowCloser extends WindowAdapter {
         public WindowCloser(){}
     
         @Override  //  method does not override or implement a method from a supertype
         public void windowClosing(WindowEvent wE)     {
            System.exit(0);
         }
      } //end class

    The code you posted is not indented at each level of nesting within a pair of {}s.
    When looking at the code you should be able to go up in a column from a } to find the line with the beginning {.

    Look at the code in post#10. Start at a } and going up in the column you find the line with the beginning {

    In your code it is not possible.

    Default Re: weekly hours for each employee

    Yes that looks somewhat better.
    Have you checked that the matching {}s for each method do not include other methods?
    To help detect this go to each ending } and add a comment saying its the end of ...
    where ... is the method name or for loop or ....
    For example:
    } // end of aMethod()
    or
    } // end of for(i)
    or
    } // end of class Employee

    When they are all labelled you should be able to see if there are any nested methods

    For me it looks like your hours method is inside the main method but since your code is poorly formatted it is hard to tell.
