public class Main {
    public static int findLargest(int[] array) {
        // Check if the array is empty
        if (array == null || array.length == 0) {
            throw new IllegalArgumentException("Array must not be empty");
        }
        // Initialize the largest number with the first element of the array
        int largest = array[0];
        // Iterate through the array to find the largest number
        for (int num : array) {
            if (num > largest) {
                largest = num;
            }
        }
        return largest;
    }
    public static void main(String[] args) {
        int[] array = {1, 4, 5, 7, 3, 9, 2};
        int largestNumber = findLargest(array);
        System.out.println("The largest number in the array is: " + largestNumber);
    }
}
Example -2 Using the Predefined functions
import java.util.Arrays;
public class Main {
    public static void main(String[] args) {
        int[] array = {1, 4, 5, 7, 3, 9, 2, 10, 0};
        // Sort the array in ascending order
        Arrays.sort(array);
        // Print the last element of the sorted array, which is the largest
        System.out.println(array[array.length - 1]);
