Thread: 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

yes to all three of your questions but since i am beginner i taught it will beneficial for me to have some people look at what i did
