Question

1. Write a function to determine maximum value in a 2-dimensional Array using passing by value, return value. Please use Java.

Answer 1

// Screenshot of the code

// Sample output

// Code to copy

import java.util.Scanner;

public class Array {

public static void main(String[] args) {

Scanner input= new Scanner(System.in);

System.out.print("Enter the no of rows: ");

int row =input.nextInt();

System.out.print("Enter the no of cloumns: ");

int col =input.nextInt();

int array[][]= new int[row][col];

System.out.println("Please enter 10 integers");

for(int i=0; i<row; i++){

for(int j=0; j<col;j++){

array[i][j]= input.nextInt();

}

}

// Calling getMax() method for getting max value

System.out.println("Maximum Value :"+getMaxValue(array));

input.close();

}

// Method for getting the maximum value

public static int getMaxValue(int[][] numbers) {

int maxValue = numbers[0][0];

for (int j = 0; j < numbers.length; j++) {

for (int i = 0; i < numbers[j].length; i++) {

if (numbers[j][i] > maxValue) {

maxValue = numbers[j][i];

}

}

}

return maxValue;

  

}
