Example 1,and 
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]);
 }
