    Default Need some Input on an application

    Hello everybody , I did an assignment for my java class and would like to have some input ; I have to create a program using a two dimensional array and average the high and the low numbers separatly and then return the largest and lowest index of the array . This is what I got so far

    public class EC {
    static final int High =12; // 12 months in a year
    static final int Low = 12; // 12 months in a year
     
    	 public static void main(String[] args)
    	    {
     
    	     int[][] Temp ={{78,83,98,67,64,87,45,59,98,75,82,68}, // Array of Low Temperature
    	    	   			{454,674,632,3265,62,478,54,428,23,76,65,45}}; //Array of High Temperature 
     
    	       GetData(Temp);
    	        System.out.println(); 
    	        averageHigh(Temp);
    	        System.out.println(); 
    	        averageLow(Temp);
    	        System.out.println(); 
    	        indexHighTemp(Temp);
    	        System.out.println(); 
    	        indexLowTemp(Temp);
    	        System.out.println();
     
    	    }
     
            // reads and store the data 
    		public static void GetData(int matrix[][] )
    		{
    	    			 int row, col;
     
    	    		    for (row = 0; row < matrix.length; row++)
    	    		    {
    	    		        for (col = 0; col < matrix[0].length; col++);
     
    		    }
    		}
    				//  calculate the average high temperature of the year
    		public static void averageHigh(int x[][] ){
     
    			int row, col = 1;
    	        int sum = 0;
     
    	    row= 1 ;
    	    for (col=0;col<x[row].length;col++)
    	    	sum = sum +x[row][col];
    	    System.out.print("The Average of High is " +sum/12);
    		}
     
    		//  calculate the average low temperature of the year
    		public static void averageLow(int x[][] ){
    			int row, col = 0;
    	        int sum = 0;
     
    	    row=  0;
    	    for (col=0;col<x[row].length;col++)
    	    	sum = sum +x[row][col];
    	    System.out.print("The Average of Low is " +sum/12);
    		}
     
     
    		// return index of the highest temperature
    		public static void indexHighTemp(int x[][] ){
     
    			 int max = x[0][0];
    			    for (int row = 0; row < x.length; row++) {
    			        for (int col = 0; col < x[0].length; col++) {
    			            if (x[row][col] > max) {
    			                max = x[row][col];
     
    			            }
    			        }
    			    }
    			    System.out.println("The largest index of the Array is "+max);
     
            }	       
    		// return index of the lowest temperature 
    		public static void indexLowTemp(int x[][] ){
    			int idx =-1;
    			    int d= x[0][0];
    			    for(int row = 0; row < x.length; row++)
    			    for (int col = 0; col < x[0].length; col++)
    			        if(x[row][col] < d) {
    			            idx = x[row][col];
    			        }
    			    System.out.println("The largest index of the Array is "+idx);
    			}
     
    }

    Is this look good or do I have to change anything ?
    Thanks

    Does it work? Does it do what you expect? Do you understand it? If the answer to all three is "yes", then I really wouldn't worry about it too much. If the answer to one of them is "no", then I'd suggest you ask a more specific question about what you have there.

    One thing I can say is that you should always obey the standard naming conventions. Classes start with an uppercase letter. Methods and variables start with a lowercase letter.

    But really, don't worry too much about doing it exactly the right way at this stage. As long as it works and you understand it, that's good enough. No matter how much time you spend getting it right, in six months you'll look at your code and cringe. That's just how programming is.
