질문 설명:
Design a class named Location for location a maximal value and its location in a two-dimensional array,The class contains public data fields row,column,and maxValue that store the maximal value and its indices in a two dimensional array with row and column as int type and maxValue as double type.
Write the following method that returns the location of the largest element in a two-dimensional array.
public static Location locateLargest(double[][] a)
The return value is an instance of Location.Write a test program that prompts the user to enter a two-dimensional array and displays the location of the largest element in the array.
프로그램 코드:
import java.util.Scanner;
public class Lll {
	public static void main(String[] args){
		System.out.println("Enter the number of rows and column columns of the array:");
		Scanner input=new Scanner(System.in);
		int row=input.nextInt();
		int column=input.nextInt();
		double[][] a=new double[row][column];
		System.out.println("Enter the array:");
		for(int i=0;i<row;i++){
			for(int j=0;j<column;j++){
				a[i][j]=input.nextDouble();
			}
		}
		Location location=new Location();
		Location.Locationlargest(a);
		System.out.println("The location of the largest element is  "+location.setmax()+" at ("+location.setrow()+", "+location.setcolumn()+")");
		
	}
static class Location{
	public static int row;
	public static int column;
	public static double max;
	int setrow(){
		return row;
	}
	int setcolumn(){
		return column;
	}
	double setmax(){
		return max;
	}
	public static Location Locationlargest(double[][] a){
		row=0;
		column=0;
		max=0;
		for(int i=0;i<a.length;i++){
			for(int j=0;j<a[i].length;j++){
				if(a[i][j]>max){
					max=a[i][j];
					row=i;
					column=j;
				}
			}
		}
		return null;
	}
}
}

실행 결과:
Enter the number of rows and column columns of the array:

3 3
Enter the array:
1 2 1
0 0 0
0 0 0
The location of the largest element is  2.0 at (0, 1)
