how to find the max value in an array java code example

Example 1: max in array java

// Initializing array of integers 
        Integer[] num = { 2, 4, 7, 5, 9 }; 
// using Collections.min() to find minimum element 
        // using only 1 line. 
        int min = Collections.min(Arrays.asList(num)); 
  
        // using Collections.max() to find maximum element 
        // using only 1 line. 
        int max = Collections.max(Arrays.asList(num));

Example 2: java max array

public static String max(String[] arr) {
  String result = arr[0];
  for (int i = 1; i < arr.length; ++i) {
    if (result.compareTo(arr[i]) < 0) result = arr[i];
  }
  return result;
}

Example 3: java max array

public static double max(double[] arr) {
  double result = Double.NEGATIVE_INFINITY;
  for (int i = 0; i < arr.length; ++i) {
    if (result < arr[i]) result = arr[i];
  }
  return result;
}

Example 4: maximum arrays size in java

int arr[] = new int[N];// Maximum Value Of N:2,147,483,647 (max int size)
