There are a few different ways that you can find the minimum value in a 2D array in Java. One way is to use the Arrays.sort() method. This will sort the entire array in ascending order, and then you can simply return the first element in the array, which will be the minimum value.
Another way is to use a for loop to iterate through the array. You can keep track of the minimum value as you iterate, and then return it once you’ve finished iterating.
Here’s an example of how you could find the minimum value in a 2D array using a for loop:
int[][] arr = {{4, 7, 2, 5}, {1, 3, 8, 9}, {6, 0, -1, 11}};
int min = Integer.MAX_VALUE;
for (int i = 0; i < arr.length; i++) {
for (int j = 0; j < arr[i].length; j++) {
if (arr[i][j] < min) {
min = arr[i][j];
}
}
}
System.out.println(min); // prints -1
What is the time complexity of finding the minimum value in a 2D array?
Assuming that the 2D array is a rectangular grid of n rows and m columns, the time complexity of finding the minimum value in the array would be O(nm). This is because we would need to scan through every element in the array to find the minimum value.
Frequently Asked Questions
How do you find the maximum and minimum value in Java?
The code to find the maximum and minimum value in Java is as follows: public static int getMaxValue(int[] numbers) { int maxValue = numbers[0]; for (int i = 1; i <= num ber s.length ; i++) { if (numbers[i] > maxValue) { maxVal ue = numbers[i]; } } return maxValue; }
How to find the maximum and minimum of a 2D array?
Set the maximum value to the largest integer in data, and the minimum value to the smallest integer in data. Sort data using Arrays.sort() and then compare the maximum and minimum values to find the array element with the highest or lowest value, respectively.
How do you find the maximum value of a number array?
In Java, you can use a for loop to find the maximum value in an array.
How to find maximum and minimum element in array using aslist ()?
Suppose we have an array of sizes that look like this:
1, 2, 3, 4
The size of the largest value in the array is 4. We can use the aslist() function to cast the array and get its max length as follows:
ArrayList
How to find maximum value in a numeric array in Java?
You can find the maximum value in a numeric array by looping through the array.
